macOS Big Sur 11.0.1 – Installation failed An error occurred while installing the selected updates.
macOS Big Sur was launched at 12:00PM CST. A few hours later, users started to report download problems.
UPDATE 02/20/21 – I’m still getting a bunch of people reaching out saying that they are still getting the error even after Apple fixed the issue! You can download the full macOS Big Sur installer directly from Apple’s servers via Safari.
What this will do is download the entire InstallAssistant.pkg file. Install this package and it will put macOS Big Sur into your /Applications folder!
UPDATE 11/12 7:30PM CST – The download is working in the Software Update pane now. LET THE BIG SUR DOWNLOADING COMMENCE!!!
UPDATE 11/12 7:00PM CST – Some users are reporting that the download is starting to work. installinstallmacos.py is working for me but I’m still getting the error in the Software Update pane.
If you were able to download the full Big Sur installer before this issue happened, then you are one of the only people with a full installer right now! Maybe you can burn it to a Dual Layer DVD and sell it on ebay haha! (will have to be a blu-ray disc as a DL dvd is only 8.5GB and the Big Sur Installer is 12.2GB LOL)
This is the error you will get on Big Sur when trying to download macOS Big Sur.
My videos explaining the issue is below.

Apple Server issues.
Apple did report a server side issue for macOS Software Updates.
That section was marked as resolved though at 3:30 CST. The problem is, the download is still not working.
The issue is with one file
After digging in, the issue is with one file installassistant.pkg
If you use installinstallmacos.py to attempt to download macOS Big Sur 11.0.1 (20B29)
curl: (22) The requested URL returned error: 403 Forbidden
Could not replicate http://swcdn.apple.com/content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg: Command '[u'/usr/bin/curl', u'-fL', u'--create-dirs', u'-o', u'./content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg', u'--compressed', 'http://swcdn.apple.com/content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg']' returned non-zero exit status 22
We do not have access to download InstallAssistant.pkg and get a 403 Forbidden Error.
Once this issue is fixed, I will will let everyone know.
Once access to this file is restored, we should be able to download Big Sur again. I will keep you updated.
Release Candidate (20B28) and the 11.0.1 Final (20B29) Release Notes are the same.

Key Features and Enhancements
Experience
Updated menu bar
The menu bar is now taller and more translucent, allowing your desktop picture to extend from edge to edge. Words lighten or darken based on the color of your desktop picture. And pull-down menus are larger, with more space between the lines to make everything easier to read.
Floating Dock
The redesigned Dock is lifted from the bottom of your display and is more translucent, allowing your desktop wallpaper to shine through. And app icons are all-new and even easier to recognize.
New icons for apps
App icons have been redesigned to feel both familiar and fresh. Icons have a uniform shape but retain the stylistic touches and details that give Mac its character.
Lighter window appearance
Windows have a lighter, more spacious appearance that makes them cleaner and easier to work with. Additional translucency and rounded edges designed to match the radii of Mac create a cohesive look and feel throughout macOS.
Redesigned sheets
Sheets in apps have been completely redesigned, removing borders and bezels to put the focus on your content. They automatically dim the background and scale into the center of the app.
New and updated sounds
System sounds are all-new and even more pleasing to the ear. The new system alerts were created using snippets of the originals, so they sound familiar.
Full-height sidebars
A new look for app sidebars makes it easier to find what you want and gives you more space to get things done. Easily track your Mail inbox, access Finder folders, and organize Photos, Notes, Stocks, and more.
New symbols throughout macOS
New symbols in toolbars, sidebars, and controls bring clarity and consistency across apps, helping you immediately recognize where to click. When apps share common tasks — like viewing the inbox in Mail or Calendar — they share the same symbol. There are also localized versions of symbols with numbers, letters, and dates to match your system language.
Control Center
Control Center
Designed just for Mac, the new Control Center consolidates your favorite menu bar items into a single place to give you instant access to the controls you use most.

Improved performance
Safari was already the fastest desktop browser — and now it’s even faster. Safari loads frequently visited sites 50 percent faster on average than Chrome.1

Privacy Report
Safari uses Intelligent Tracking Prevention to identify trackers and help prevent them from profiling or following you around the web. A new Privacy Report shows how Safari protects your browsing across every website you visit. Go to the Privacy Report from your Safari menu and you’ll get an in-depth overview of every cross-site tracker prevented over the last 30 days.

MacAdmins at work!
It’s amazing to see MacAdmins working together to solve an issue. Yesterday afternoon a bunch of Admins including @golby, @eholtam, @owen, @dave.shepp, @macmule, @matt_h and @deets jumped in to help figure this out and pass on the information to others.
Today Apple released macOS Big Sur Beta 11.0.1 Beta 2 Release Candidate (20B5022a) to Developers
MacOS Big Sur 11.0.1 Beta 2 was released on November 5th, 2020. The release comes about one week after 11.0.1 Beta 1. We were expecting RC or GM seed, but not yet! It’s possible that we will see the public launch of 11.0.1 at the Apple Silicon Mac “One more thing” event on November 10th.
That’s all folks! I hope that you were able to get all your Big Sur bugs fixed! This version is most likely the release that we will see this Tuesday!

(55068348)Workaround: During development, you can temporarily disable System Integrity Protection to allow these deprecated kernel extensions to load.
New in macOS Big Sur 11.0.1 Release Candidate, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286)
Use only absolute paths with the --volume-root option of kmutil, and don’t use a trailing /. (63773848)
Symbols exported by both xnu and Apple kernel extensions will change. Recompile your kernel extension with each update to macOS Big Sur 11.0.1 Release Candidate to ensure compatibility. (64262563)

Mac Transition to Apple Silicon – Everything you Need to Know!
Apple Silicon Macs will be here soon!
Apple said the first Apple Silicon Mac will launch before the end of 2020. The launch date is quickly approaching, now is the time to get up to speed! I will be following my “Everything you need to know” format from my previous articles.
This article will be updated as new Apple Siliconinformation comes in.
The feedback that I’ve received from these has been really great. The big takeaway is that everyone really likes how all the information is all in one place. You are not wasting time looking for that one article, command or link.
NOTE: Everything in this article is public knowledge from Apple. Once the first Apple Silicon Mac ships, I will post more in depth articles.
Apple Silicon changes the way in which we enter recovery on the Mac. In the past, we had to remember multiple keyboard commands. On Apple Silicon, all you need to do is hold down the power button. In a few seconds, you will see the new Apple Silicon Startup Manager.
7. How to use the new start manager on Apple Silicon
To enter Apple Silicon Startup manager follow these steps.
1. Hold down the power button
2. You will see the message “Continue holding for startup options”
3. The next message will say “Loading Startup Options…”
4. You will now see the new Apple Silicon Startup Manager.
Apple Silicon Mac Startup Manager Options
The startup manager will show you the main boot disk (Macintosh HD) Boot icon and Recovery Options. Click “Options” to boot into macOS Recovery.
8. Internet Recovery is dead on Apple Silicon
Have you had trouble booting into Internet Recovery in the past? You are not alone. Now with Apple Silicon, Internet recovery is officially retired. It will still remain for Intel based Macs. For Apple Silicon we now have 3 different ways to reinstall macOS.
1. macOS Recovery = First line of recovery.
2. System Recovery = Hidden partition for when normal macOS recovery is not available.
3. macOS System Restore via DFU mode + Apple Configurator 2.
9. Apple Silicon macOS Recovery
Apple Silicon macOS Recovery is almost exactly the same as it is on Intel Based Macs. The only difference is Security Policy options was moved from the Menu bar to the “Startup Disk”.
First line of defense, is macOS Recovery.
10. Apple Silicon System Recovery
Apple Silicon System Recovery is a new hidden recovery option in addition to macOS Recovery. If for some reason macOS Recovery becomes corrupt, System recovery will load which is the same as macOS recovery. You can use it to reinstall macOS and macOS Recovery.
System Recovery is a hidden non deletable container. It’s a new way to reinstall macOS when recovery is not available.
11. Both macOS Recovery and System Recovery are not available?
The blinking folder icon is now retired. If the Mac is not bootable, you will now see an old friend.
The sad Mac returns when Macintosh HD, Recovery and System recovery are not available.
12. Apple Silicon External Boot Options – USB Installer
On Apple Silicon external boot remains, but has changed.
External Boot for the macOS installer is now enabled by default
You no longer need to enter Security Options to enable External Boot!
You can build out a USB Installer of macOS Big Sur and boot your Apple Silicon Mac to it. The big difference that ONLY the installer is available for a reinstall of the OS. You can NOT erase the drive in this mode.
You can now boot a USB macOS installer without enabling external boot in Security options! It’s enabled by default.
13. How to Use Apple Configurator 2 to reinstall macOS on Apple Silicon
If all options to reinstall macOS fail you can now use Apple Configurator 2.
This will help with rapid deployment in lab / school situations.
14. Apple Silicon Security Policy
We know that an Apple Silicon Mac will have 2 Security modes.
Apple Silicon Security Policy menu
1.Full Security = “iOS Security” – Only the latest signed version of macOS can be installed on an Apple Silicon Mac.
Full Security
Ensures that only your current OS, or signed operating system software currently trusted by Apple, can run. This mode requires a network connection at software installation time.
WWDC 2020
2. Reduced Security = Any version of macOS that was signed by Apple.
Reduced Security
Allows any version of signed operating system software ever trusted by Apple to run.
WWDC 2020
With the new Apple Silicon Security Policy, you can set a security policy for each container! On an Intel based Mac the security policy would be set on the entire system.
New Apple Silicon Security Policy can be set differently on each container.
15. Apple Silicon Compatible Versions of macOS
Will you be able to install older versions of macOS? A quick review;
Full Security = iOS based security, only the latest signed version of macOS can run on the system.
Reduced Security = Any version of macOS that was signed by Apple can run on Apple Silicon
Note: The shipping OS version will be the oldest OS available to install.
16. Can I downgrade macOS on Apple Silicon?
Yes! But only with your Apple Silicon Security Policy set to “Reduced Security”.
17. How to use SMB Mac Sharing Mode (Replaces Target Disk Mode – TDM)
Target Disk Mode has been retired on Apple Silicon. It was replaced with Apple Silicon Mac Sharing Mode.
Boot to macOS recovery and then select “Mac Sharing Mode” you will be able to transfer data over USB-C cable. You will need to authenticate with a SecureToken User that is on the host Mac.
Mac Sharing MOde replaces Target Disk Mode.

Do you need to downgrade Safari? I will show you 2 ways to do it.
If you recently installed the Mojave Supplemental Update and were surprised to see Safari 14.0 installed, you are not alone.
UPDATE 4/30/21 – This article explained originally how to downgrade from Safari 14.0 to 13.1.2 due to a problem. Apple has pulled the Safari 14.1 Update for both Catalina and Mojave. Users are reporting the error Safari 14.1 = webpage loading errors “a problem repeatedly occurred”. You can attempt to use the same instructions to downgrade from Safari 14.1 to 14.0.3. I’ve included Safari 14.0.3 download links at the bottom
Confirmed the following after reinstall of 10.14.6 over the top of current install (retains user data) Build Version (18G103) Safari 12.1.2 Software Update shows Security Update 2021-003 & Safari 14.0.3 Good workaround until Apple releases a fix ? Should be the same for 10.15
You are probably asking yourself, why would anyone want to downgrade from Safari 14 to 13. Safari was offered as a separate download in software update so users could remain on Safari 13 if they wanted. This was fine until the 2020-005 Security Update started to break systems. After issue, Apple re-issued Safari 14.0 but renamed it “Mojave Supplemental Update”. This caught many off guard because they didn’t understand that installing this update was actually installing Safari 14.0.
Readers wrote in and asked me if there is a way to downgrade Safari. Many still needed Flash, others had website compatibility issues. Some just really missed Top Sites. Another big problem was that some users upgraded to Safari 14.0.1 Beta. They are still broke because the supplemental update did not include 14.0.1 as a compatible upgrade version. I recommend that you do anything possible so you don’t need to downgrade. Most users will be just fine with Safari 14. The new version includes user privacy improvements and security fixes.
Mr. Macintosh How to Downgrade Safari 14.0 to 13.1.2 video.
Supported and Unsupported
I will show you 2 different ways to downgrade from Safari 14.0 to 13.1.2.
1. Supported Way – Reinstall (not erase and install) macOS Mojave 10.14.6 (18G103) = Safari 12.1.2
2. Unsupported Way – Disable SIP protection > Remove Safari 14.app and Files > Install Safari 13.1.2 > Enable SIP again = Safari 13.1.2
When I say Supported I mean this is what Apple would recommend and is the best path forward. Unsupported is what some users have done the past that might or might not have some compatibility issues. Consider this a warning. I have tested this multiple times and not had an issue, but you might! So please backup before you test this path. You can always install Safari 14.0 again if needed.
The following instructions are only for macOS Mojave.
I did not test this on Catalina or High Sierra, but I’ve included download links below if you would like to try. Readers who have contacted me were only asking about Mojave because of the Supplemental Update naming issue.
Supported Way = Reinstall macOS Mojave
The is pretty cut and dry, you will reinstall macOS Mojave 10.14.6 over the top of your current version of Mojave. An example of this that you are running 10.14.6 (18G6032). This is the latest version of Mojave available and includes all the security fixes in the 2020-005 Update. If you want to see a full listing of macOS versions, take a look at my macOS System Status and Versions Page. After reinstalling macOS Mojave you will be at version# 10.14.6 & BuildVersion number (18G103). Safari will be at 12.1.2.
1. Backup all your files (always a good thing just in case)
2. Reboot to the Recovery Partition (Command R)
3. Click Install macOS
4. You are now at macOS Mojave 10.14.6 BuildVersion 18G103 and Safari 12.1.2
5. Install Safari 13.1.2 (download link below)
6. Install Security Update 2020-004
7. NOTE: I did NOT test installing the 2020-005 Security Update after. The Safari 13.1.2 + 2020-004 Security Update install order was offered by Apple when the 2020-005 update was pulled. This was a tested path by them and is supported.
You are back on Safari 13.1.2! Keep in mind you aremissing important security updates. I hope that you can fix any compatibility issues that you may have and get on the latest version.
Unsupported Way = Uninstall Safari
As mentioned above, this is an unsupported path. Please backup your files or run a time machine before attempting this. Another thing you could do is run a tmutil localsnapshot /. You could immediately revert back to before any changes if needed. Remember the localsnapshots only last for 24 hours! I have tested this multiple times and have not found any issues, but you might! Let’s get started.
1. Make a backup first!
2. Disable SIP
3. Boot to the recovery partition > Open Terminal > Type in csrutil disable
10. Use AppCleaner to remove Safari 14.0 – Go to preferences and uncheck “Protect default OS X apps”. Drag safari.app over to the app then select all files. then click remove.
11. Install Safari 13.1.2MojaveAuto.pkg using Pacifist.app – Drag Safari13.1.2MojaveAuto.pkg over to the app. A new window will pop up. Highlight the main pkg in the list then hit install. You will see 2 admin prompts and a prompt to overwrite files, select overwrite all.
12. Reboot to recovery and re-enable SIP. Open Terminal > Type in csrutil enable
13. Reboot back to macOS. You are now back to Safari 13.1.2

Apple has just released the macOS Mojave 10.14.6 “Supplemental Update” which is a fixed version of Safari 14.0
The macOS Mojave 10.14.6 Supplemental Update is Live! It includes a fixed version of Safari 14.0. The update also address the problems of the previous release. Security Update 2020-005 was also re-released.
Apple has just released a Mojave Supplemental Update that address all the problems that the previous Safari 14.0 and 2020-005 Security Updates! This news comes one day after Apple pulled both software updates from the software update catalog.
You can find a full summary of the issue in the link below.
UPDATE 10/08 11:30PM – Safari 14.0.1 Seed 2 was just released today. Mr. Macintosh reader Joe wrote in to let me know that after he installed Seed 2 over Seed 1 all of his problems went away! This will be a perfect fix for anyone who installed Safari 14.0.1 Seed 1 and were still having problems (since the Supplemental Update was not compatible with 14.0.1).
UPDATE 10/03 3:00PM– I’ve added a direct download link to the safari 14.0 package from the software update service in section 16 below. Apple has also added back the Mojave 2020-005 Security Update back to Apple.com downloads. The security update link is also in section 16 below.
UPDATE: 10/02 3:00PM – NOTE: Apple still has an old link to the Supplemental Update from 9/26/19 up on the the Apple downloads site. This is NOT the update you need. Apple has not released a stand alone download for this update yet. The update is only available from software update.
UPDATE: 20/02 10:30AM – I’ve added section 5 to make sure you know that the Supplemental Update will install Safar 14.0. This is important to understand in case you needed to remain on Safari 12 or 13. Some users are asking me what they should so if they installed Safari 14.0.1 Beta. I’m looking into that now.

18. Final Thoughts
19. Thank You
1. Name of the Update?
Apple calls this update “macOS 10.14.6 Supplemental Update” Which is a bit confusing. In this particular case, the naming might make sense. Even though the update only includes a fixed Safari pkg, it also includes fixes that repair previous install OS level issues.
softwareupdate -l shows the name. It’s technically called Safari14.0MojaveAuto-10.14.6
NOTE!!! The update also includes a required restart. (Normal Safari Updates do not require a restart.)
2. Details of the macOS Mojave Supplemental Update
Along with the new Supplemental Safari Update, the Mojave 2020-005 Security update was re-released back into the software update catalog.
5. The Supplemental update will install Safari 14.0!
I need to make this clear, If you do not want Safari 14.0 don’t install the new macOS Supplemental update! I’ve heard from a few users who need to remain on the old version. Only update when you are ready to make the jump to Safari 14.0
6. Inside the macOS 10.14.6 Supplemental Update
So if this is not a normal supplemental update, what is it?
This is what’s inside of the macOS 10.14.6 Supplemental Update (FIxed Safari 14.0)
As you can see, this update only has the fixed version of Safari 14.0 inside! NOTE: this update has a REQUIRED RESTART!
What does a normal supplemental update look like?
This is what’s included in a full Supplemental Update. This is the 10.14.6 Supplemental Update #2
As you can see a normal “Supplemental Update” includes a bunch of stuff. I just wanted to clear up any confusion that you might have. (I was confused when I first saw the update.)
7. Which update does your Mac need?
We have multiple scenarios to work with here. I have used a test Mac to go over the many situations that a user might be in so you are not left wondering what to do!
1. Did you install ONLY install – Safari 14.0?
2. Did you install ONLY install – 2020-005 Security Update?
3. Did you install BOTH Safari 14.0 & Security Update 2020-005?
4. Did you not install either of the updates?
Below is a screenshot of what About This Mac > System Report > Installations will look like.
System Report – This is what it would look like after installing both problematic updates then installing both fixed updates.
8. Did you only install – Safari 14.0?
Let’s say that you installed Safari 14.0 a few days ago but heard the news about all the problems that the 2020-005 security update was causing.
Your Safari Version is = 14.0 (14610.1.28.1.9)
You will see the following in Software update.
This is what you will see if you only installed the old version of Safari 14.0
The following will happen in this scenario.
Fixed version of Safari Supplemental Update + fixes update will be installed
The Re-Released version of Mojave 2020-005 Security Update will install
Reboot
You are now fully up to date with no issues!
Mojave will be on the same Build Version 10.14.6 (18G6032)
Safari version is UPDATED – 14.0 (14610.1.28.1.10)
You are good to go!
9. Did you only install – 2020-005 Security Update?
Let’s say you need flash and you didn’t want to install Safari 14.0. But you did see the Security Update 2020-005 and installed it. In this situation, you would still be fine (maybe) even if you installed the old version of Safari 14.0. The problem would only happen if you installed Safari 14.0 first then the 2020-005 update.
What would you see in software update?
You only need to install the Supplemental Update (Safari 14.0 Fixed) and will be good to go!
In this case you would only see the fixed Safari 14.0 Supplemental Update.
Once installed you are good to go!
10. Did you install BOTH Safari 14.0 & Security Update 2020-005?
Let’s say that you had automatic updates set and you got both updates. Your system is in a broken state.
What would you see in software update?
What you would see in SU if you previously installed both problematic updates.
The following will happen in this scenario.
Fixed version of Safari Supplemental Update + fixes update will be installed
Reboot
You are now fully up to date with no issues!
Mojave will be on the same Build Version 10.14.6 (18G6032)
Safari version is UPDATED – 14.0 (14610.1.28.1.10)
You should be fixed!!!
11. Did you not install either of the updates?
Let’s say that you heard of the news of the problematic updates and were able to save your Mac.
What would you see in software update?
This is what you would see on a mac with 10.14.6 (18G6020) and Below.
You would see both updates
The following will happen in this scenario.
Fixed version of Safari Supplemental Update + fixes update will be installed
The Re-Released version of Mojave 2020-005 Security Update will install
Reboot
You are now fully up to date with no issues!
Mojave will be Build Version 10.14.6 (18G6032)
Safari version now – 14.0 (14610.1.28.1.10)
You are good to go!
12. Not seeing the 2020-005 Security Update?
You might have either installed the update or ignored it by running
If you would like to install the re-released version of the 2020-005 Security Update, all you need to do is run this command.
sudo softwareupdate --reset-ignored
The security update will now show up in software update for you to install.
14. Did you install Safari Beta 14.0.1 ?
I am testing this situation out now.
Yikes, looks like the Supplemental Update does not show up if you have installed Safari Beta 14.0.1. The installer will let you install the Supplemental Update over the top of the 14.0.1 Beta, but does not actually install.
15. Did I cover all the situations that you could be in?
Did you have an install scenario that I missed. I attempted to cover and test them all. Let me know!
16. 10.14.6 Supplemental Update Links
Apple has not released a standalone installer or pkg for the supplemental Update. I’ve included direct links from the Software Update Service below. Apple has added the Mojave 2020-005 Security Update back to the Apple.com downloads page.
It was really cool to see this little blog mentioned. 🙂
With that said, I think Apple handled this pretty good. They might have taken a bit to pull the update, but they came out with a fix only one day later!
Hopefully we can get a closer eye on update quality moving forward.
19. Thank You
I wanted to thank all of my Mr. Macintosh readers, Twitter followers, YouTube Subscribers and those who emailed me. You have shared so many of your thank-you notes, comments, tips and fix stories. I really appreciated reading them all, I created this blog for you! I am finally at a point in my life where I can take all of the knowledge that I’ve learned along the way and share it with you.
Today Apple released macOS Big Sur Beta 9 (20A5384c) to Developers
MacOS Big Sur 11 Beta 9 (20A5384c) was released on September 29th, 2020 only one week after Beta 8! We are starting to get weekly beta releases. MacOS Catalina had 11 beta releases including the gold master, so again we are getting very close to release. Beta 7 & 8 did not get a full installer so hopefully we get one this time around. I’m still waiting to see if any changes are listed around screen recording, I will update as soon.
UPDATE: 10/05 – softwareupdate --fetch-full-installer does not work in Big Sur Beta 9
UPDATE: 9/30 – Apple has just released a Beta 9 Full Installer!!!
Released on 9/30 at 12PM CST a Beta 9 Full Installer!
UPDATE 9/29 – Items not found in Big Sur Beta 9 official patch notes
Beta 9 does not have a full installer available 🙁
We now control screen recording access for standard users with MDM! (More information available in the AppleSeed patch notes)
Active Directory login is still not working in Beta 9. Hopefully it’s fixed in the next release. The plugin was working fine in Beta 6 and 7.
Xcode command line tools are now available for 12.2 Beta 2
Setup assistant bug where you could not hit continue = Fixed.
Beta 9 seems to take longer to prepare the install (30min+)
2. Updating to macOS Big Sur 11 beta from previous versions of macOS might take significantly longer than expected. Data loss could occur if the update is interrupted. (59101197)
Previous Big Sur 11 Beta Releases
9. Big Sur 11 Beta 9 (20A5384c) – 09/29/20 – Current Release
Now that macOS Big Sur 11.0 Beta is live, start testing as soon as you can! You will want to submit any bugs that you find into Apple ASAP. If you get bugs in quickly, they could be fixed in the current beta cycle instead of waiting until after the public release. If not, you could be waiting months before the fix is put into a dot release combo update.
macOS Big Sur 11 Beta 9 (20A5384c) Release Notes
Overview
The macOS 11 SDK provides support to develop apps for Macs running macOS Big Sur 11. The SDK comes bundled with Xcode 12.2 beta, available from Beta Software Downloads. For information on the compatibility requirements for Xcode 12.2, see Xcode 12.2 Beta Release Notes.
If you install Security Update 2020-005 for Mojave, you could run into major issues!
Multiple reports are coming in from users who are starting to have major problems after installing the latest Mojave 2020-005 Security Update.
UPDATE #8 – 10/01 10:00PM –Apple has just released a fix and I’ve just finished an article going over all the details. I tried to test and figure out every scenario that you might be in, so you know exactly what will happen.
UPDATE #5 – 9/28 7:30PM – I have added 3 new sections below. The first one shows you how to ignore the Mojave 2020-005 Security Update. The second will show you a very quick way to find out if your Mac is affected by this issue. In the 3rd, I will show you 4 different install scenarios. We now know the issue only happens if you install Safari 14.0 first, then install the 2020-005 update after. An example of a Mac that would unaffected by this issue would be if you installed the 2020-005 Security Update first, then the Safari 14.0 update after.
UPDATE #4 – 9/28 12:30PM – I have reproduced the install problem flow Please read section #5 below for more info. You can install the Mojave 2020-005 Security update WITHOUT Safari 14.0 and not have any issues. You can even Install Safari 14.0 after and not have any issues. It’s only when you install Safari 14.0 first then install 2020-005 after when the problems start! I will continue to test this and post updates.
UPDATE #3 – 9/28 11:30AM – After running some more tests, Safari 14.0 could be one of the problems. The next test performed was to build a fresh 10.14.6 Mac and install only the 2020-005 Security Update = No problems. I then installed Safari 14.0 = No problems. Then I reinstalled 2020-005 again = All Problems are back!!! I am going to check the order, maybe if Safari 14.0 is being installed first with softwareupdate this could be part of the problem. I am going to continue to test to find out more.
9/27
UPDATE #2 – 9/27 5:00PM – I am keeping an eye on Apple’s Software Update Server to see if they pull the update. I will update if they do.
UPDATE #1 – 9/27 3:30PM – A few users have asked if they can install the 2020-004 update over the 2020-005 update. They mentioned being able to do this in the past. Usually you can’t go backwards using Apple’s .pkg installers. I tested this out and sure enough, the installer says that a newer version of this update is installed. Apple didn’t design the installers to undo newer security updates. This is unlike the full .app installer which can replace all OS level files.
This article will include will be continually updated with the latest information on this issue.
I have some workarounds and fixes that could help you if you already installed the Mojave 2020-005 Security Update.

One of the two will be used. Which one is undefined.
4. How can I ignore this update in software update?
All you need to do is use the softwareupdate ignore option.
I discovered last night that on my Mojave test Mac that I couldn’t reproduce the issue even though I could on my 2nd test Mac. I realized that I only installed the 2020-005 Security update and NOT the Safari 14.0 update. This is when I restored back to the previous snapshot and tried again. For the next test, I let software update install both updates. Safari 14.0 was first then 2020-005, after the reboot I had the problem. Let’s go over a few of the install scenarios below.
Scenario #1 How to install both Updates and be affected by the issue.
1. 10.14.6 (18G103) Base Install
2. Use software update to install both Safari 14.0 and 2020-005 Updates
3. After the restart = You will have the problem.
Scenario #2 You installed Safari 14.0 as soon as it came out on 9/16
1. 10.14.6 (18G103) Base Install
2. Install Security Update 2020-005 + Reboot = You will have the problem
Scenario #3 How you can install both updates with NO PROBLEMS
1. 10.14.6 (18G103) Base Install
2. Install Security Update 2020-005 ONLY + Reboot = No Problem
3. Now Install Safari 14.0 = No Problem
Scenario #4 How you can install both updates with in the correct order and still have the problem
1. 10.14.6 (18G103) Base Install
2. Install Security Update 2020-005 ONLY + Reboot = No Problem
3. Now Install Safari 14.0 = No Problem
4. Install Security Update 2020-005 AGAIN + Reboot = You will have the problem (NOTE: the same problem happens if you use the 2020-004 installer in this step)
3. User Reports.
The first report came in on Thursday, just 4 hours after Apple released the Mojave 2020-005 Security Update.
Is anyone getting really low free RAM after applying this update? Activity Monitor says I have 12GB of RAM used right after I launch it after logging in.
I applied the 2020-005 Security Update today to my MacBook Pro running Mojave (10.14.6) and after it restarted, I started experiencing problems. The first and most obvious is the Dock crashes repeatedly. I have also noticed that when running applications, the menu bar does not display the app’s menus, but stays showing Finder menus. I downloaded the .dmg file with the updater on it and applied it again, thinking perhaps something went amiss the first time, but it did not resolve the issue.
After doing this job for many years, I get an sense when things are starting to become an issue. Just to be sure, I always wait for more reports and attempt to reproduce the issues myself before reporting.
Additionally, boot time is slower, logging in is slower and when doing so I’m met with a blank desktop which needs 7-8 seconds before icons finally appear. Everything feels sluggish, and applications also take more than twice as long to start up.
After reading multiple reports I felt that it was time me to take a closer look. Sure enough, more users have started to report the same issues.
4. This time around the issues can be reproduced
When issues like this have come up in the past, I might not be able to reproduce them. I have to go purely on user reports, which at times can be tough. I want to make sure the reporting is very accurate. Especially when I am recommending that users not install a security update. This time around is different, I have tested the update on multiple Macs and can reproduce most of the issues. I also found a few that have not been reported on the forums or twitter.
5. A Fix! Rolling back with Automatic Update Snapshots. (within 24 hours of install)
Do you have time machine backups?
If you do, just restore and you are good to go! Now would be a good time to start. If not keep reading.
Automatic Update Snapshots was introduced as a feature in macOS High Sierra. You can read about them below. This was one of the best features that Apple has ever added to macOS. Sadly they only work for 10.13 and 10.14 Security Updates and not 10.15 Catalina Combo Updates.
Automatic Update Snapshots could save you, if you installed the Mojave 2020-005 Security Update in the last 24 hours. That’s the problem with tmutil localsnapshots they only last 24 hours!!! So if you installed the update you might still be able to roll back to the previous Mojave Security Update 2020-004 (18G6020).
Steps to restore from an Automatic Update Snapshot.
Reboot to recovery. Hold down Command R
Once in recovery select “Restore from Time Machine Backup”
On the next screen select “Macintosh HD”. If your Mac is filevault encrypted you will be asked for your password.
On the next screen, if you have a snapshot available it will look like this.
If you have an automatic update snapshot available, this is what it will look like.
5. Select it and hit continue! Your Mac will now restore back to the snapshot taken just before the 2020-005 Security Update was installed.
But what if 24 hours has past since you installed the update? Keep reading below.
6. Workarounds
If you don’t have an Automatic Update Snapshot available, hopefully one of the following options will help you.
Upgrade to Catalina. This was recommended by Apple Support. If don’t want to upgrade to Catalina yet, scroll down to option #2.
We’d like to see how we can help. We recommend upgrading to the latest macOS Catalina by following the steps in this link: https://t.co/cCbnQHhGBJ
This workaround will reinstall macOS Mojave 10.14.6 (18G103) and you will be able to keep all your files and applications. All you need to do is download the Mojave Full installer from the App Store and reinstall. To keep your Mac protected, you can install Security Update 2020-004 and not have any issues.
You can also perform an erase and install if you have all your files backed up.
@AppleSupport@havertyj@vitahallo We operate a fleet of about 350 Macs, and are seeing issues with extreme stalling after Security-Update 2020-005 and 10.15.7. Not all of our machines, but enough that it concerns me. Standard troubleshooting has not helped… any news or help?
@Apple I installed the 2020-005 Security Update for my MacBook Air and now the computer is super slow, has no free memory left even when it just booted up, and it takes ages to start up programs. Can you give me instructions on how to uninstall the update?
@AppleSupport The newest security update for Mojave—2020-005 10.14.6—slowed my computer to a crawl and caused nearly constant freezes. I had to roll-back to a previous version. It's a late 2015 27-inch iMac, serial C02SH3TBGG7J
Multiple Hat tips go out to my website and twitter followers for reporting the issue to me so I could take a closer look. Special thanks to Hyram Hakkenbecker for double-checking my articles for any grammar issues that sneak past!
What’s New in the macOS Catalina 10.15.7 Update (19H2)?
macOS Catalina 10.15.7 Update is now Available!
For the first time since Mac OS X Snow Leopard, Apple has progressed past a .6 point release! I’m very happy with this change, as it’s easier to understand dot releases compared to supplemental updates. This is the 21st update overall for macOS Catalina.
UPDATE! 9/29/20 – I just posted an article talking about the Catalina 10.15.7 Update accountsd process using 400%+ CPU.
UPDATE! 9/27/20 –A few reports are coming in that the 10.15.7 update is causing some problems with the accountsd process. After the installing the 10.15.7 update, accountsd runs up to 400% in Activity Monitor. The issue might happen for some users that are using iCloud for Drive, Mail or Cal. Other reports say the issue can happen if you are using internet accounts with Gmail. This issue causes system slowness until resolved. Most fixes say to log out of iCloud or Gmail then restart.
