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.

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

WebExtensions API support
New support for the WebExtensions API and migration tools allows developers to bring Chrome extensions to Safari — letting you personalize your browsing experience with new Safari extensions from your favorite developers.
Grant extensions website access
Keep the websites you visit and tabs you use even more private. Safari asks you which websites a Safari extension can work with — and you can grant access for one day or all the time.
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.

Installing a new kernel extension requires signing in as an Admin user. You must also restart your Mac to load the extension. Kernel extensions using certain deprecated KPIs won’t be loaded. For more information, see Deprecated Kernel Extensions and System Extension Alternatives. (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 2, 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 2 to ensure compatibility. (64262563)
SwiftUI
Known Issues
ProgressView generic type signature has changed, adding the currentValueLabel generic parameter. This change doesn’t require any source changes, but it causes apps compiled using an earlier beta SDK to quit unexpectedly. (63580200)Workaround: Re-compile apps for macOS Big Sur 11 Beta 6 or later to resolve this issue.
Third-Party Apps
Known Issues
You might experience kernel panics when using earlier versions of Parallels Desktop 16. (67358596)Workaround: Upgrade to the most-recent version of Parallels Desktop 16.
Some third-party scripts might produce unexpected results due to the change in macOS version from 10.x to 11. (62477208)Workaround: Set SYSTEM_VERSION_COMPAT=1 in the calling environment, for example: $ SYSTEM_VERSION_COMPAT=1 legacy_script.pl
Wallet
Known Issues
isPassLibraryAvailable() doesn’t ensure uniform availability of pass library functionality between platforms and devices. (60697880)Workaround: Call a more specific API to check available functionality, such as canAddPasses().
Xcode
Known Issues
Legacy Xcode versions prior to 11.5 might unexpectedly quit when launched. (59991056)Workaround: Run the following command in Terminal: defaults write com.apple.dt.Xcode DVTDisableMainThreadChecker 1, then deselect Main Thread Checker in the Diagnostic tab of the Run and Test actions for each scheme in your project.
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!

macOS Catalina 10.15.7 Supplemental Update is now Available.
UPDATE 11/11/20:Apple has just released a full installer for macOS Catalina 10.15.7 that includes the Supplemental Update Security Fixes! No word of an updated combo update or a downloadable pkg yet. I will update if they become available!
Today Apple released the 6th Supplemental Update for macOS Catalina. With the release of 10.15.7, we thought Apple would continue with an easy way to identify updates. The 10.15.7 Supplemental update seemed to dash those hopes. The update does not even list any fixes in it. The only wording is
“macOS Catalina 10.15.7 Supplemental Update is recommended for all users and improves the security of macOS”
This tells us that the update only has security related fixes in it!
In the security link, Apple calls out 3 security vulnerabilities. I will go over them below.
Mr. Macintosh Catalina 10.15.7 Supplemental Update Video
The macOS Catalina 10.15.7 Update includes the following Security fixes.
macOS Catalina 10.15.7 Supplemental Update provides important security updates for your Mac.
This update is an important update due to this quote from Apple
A malicious application may be able to execute arbitrary code with kernel privileges. Apple is aware of reports that an exploit for this issue exists in the wild.
Apple
The Supplemental Update patches the following
FontParser arbitrary code execution = Found in the wild!!!
Two Kernel Exploits = Both found in the wild!!!
All three vulnerabilities have been reported to Apple from the Google Project Zero Team.
Treat this Supplemental Update as a High Priority!
Confusing Update Situation
We have a couple update scenarios that we need to discuss. Normally Apple releases new Delta and Combo Updates. This time we only have a delta update for 10.15.6 users. If you have anyone on 10.15.0-10.15.5 they will be offered the OLD 10.15.7 (19H2) Update. They will have to install the 10.15.7 Supplemental Update after!
10.15.7 users = NEW 10.15.7 Supplemental Update
10.15.6 users = NEW 10.15.7 Delta Update
10.15.0-10.15.5users = OLD 10.15.7 Combo Update – Will need to install the 10.15.7 Supplemental Update after.
10.15.7 Full Installer = Remains OLD 10.15.7 (19H2) version and will need to install the 10.15.7 Supplemental Update after.

Apple’s Public Patch Notes / Release Notes Documentation
NOTE: Apple Documentation takes a little while to show up online after release. I will update when the new articles are made available.
The following security fixes are included in Catalina 10.15.7.
Released November 5, 2020
FontParser
Available for: macOS Catalina 10.15.7
Impact: Processing a maliciously crafted font may lead to arbitrary code execution. Apple is aware of reports that an exploit for this issue exists in the wild.
Description: A memory corruption issue was addressed with improved input validation.
CVE-2020-27930: Google Project Zero
Kernel
Available for: macOS Catalina 10.15.7
Impact: A malicious application may be able to execute arbitrary code with kernel privileges. Apple is aware of reports that an exploit for this issue exists in the wild.
Description: A type confusion issue was addressed with improved state handling.
CVE-2020-27932: Google Project Zero

If you are on iOS 14.2 Beta 4, you are getting this message now. (An update is not available though!)
If you are on iOS 14.2 Beta 4, you are getting this message now. (The update is not actually available!)
Have you had enough of this message yet? The answer is most likely YES. You just want it to go away. The message shows up every time that you unlock your iPhone or iPad screen if you are on iOS or iPadOS Beta 14.2 Beta 4.
UPDATE 10/30 7:00PM CST – Apple just released iOS 14.2 Release Candidate (Previously named GM). This new update fixes the constant pop up box issue! Update video below.
A new iOS update is now available. Please update from the iOS 14 beta.
CLOSE!
What can you do about this message?
Part 1 – Mr. Macintosh Video on the “A new iOS update is now available”pop-up problem.
Part 2- Mr. Macintosh UPDATE Video on the “A new iOS update is now available”pop-up problem.
This isn’t the first time that we’ve seen this message.
Just about two years ago, this same exact message came up for iOS 12 Beta users. Guilherme Rambo figured this out by looking at the code.
It looks like this method in Springboard does some date/time calculations to determine if the current build is about to expire, every time the cover sheet gets dismissed. For some reason, the latest builds of iOS 12 think they're about to expire. (@davedelong :P) pic.twitter.com/HWe7C0NnIT
I will show you 3 quick ways how to fix this issue.
UPDATE 10/30 7:00PM! – Apple has released iOS 14.2 Release Candidate Beta! This update fixes the constant pop up problem! Be sure to turn automatic time back on and reinstall the beta profile if you removed it. You will now see the update!
1. Wait for Apple to publish iOS 14.2 Beta 5. This happen two years ago when the iOS 12 Beta pop up problem happened. Apple pushed quick fix the next day.
2. Move your clock back to the 26th or before. The timer was set to start warning the user. This is temp fix, that could cause issues with some websites & apps like twitter, Gmail or Instagram.
3. Restore to your iOS 14.1 production backup. Maybe you have had enough of the Beta 14.2 and just want to go back to the production version.
Again, I recommend just waiting a day or two for Apple to release a fix. I will update when Apple has published the new beta.
Mr. Macintosh Quick overview of the DTK Developer Labs
I’m hoping the DTK labs are setup just like the virtual WWDC 2020 labs.
I was lucky enough to be picked for 2 out of 3 labs that I signed up for at WWDC 2020.
I really was not sure what to expect. When I joined the call, two Apple Engineers were on the call waiting. We introduced ourselves and immediately jumped in and started to talk about the questions that I had.
Both Engineers had answers to every question that I had. The entire experience was great. This is something that MacAdmins need, the ability to talk directly with engineers about the issues they are facing every single day.
If the Apple Silicon labs are anything like the WWDC Labs, then you will defiantly be happy. Don’t miss your chance!
Everything you need to know about Apple Silicon
Be sure to check out my new “Everything you need to know” article on Apple Silicon. The article will be updated as new information comes in!
Today Apple released macOS Big Sur Beta 11.0.1 Beta 1 (20B5012d) to Developers
MacOS Big Sur 11.0.1 Beta 1 was released on October 28th, 2020. The release comes about 2 weeks after Beta 10. We were expecting Beta 11 or a GM seed, so it’s strange that we are getting 11.0.1 Beta. It’s possible that Apple Silicon Macs (currently in active production) will have 11.0 installed on them. When they arrive they will see 11.0.1 as an available update.
UPDATE: 10/29
Full Installer now available!
Fixes VP9 Safari YouTube Codec Error

11. Big Sur 11 Beta 11.0.1 (20B5012d) Beta 1 – 10/28/20 – 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.

On Friday October 23rd, HP printer owners started reporting that they couldn’t print. The error message = HPDeviceMonitoring.framework will damage your computer.
UPDATE: 10/28/20 – I just finished my new video that goes over the issue. I also give a live demo of how to uninstall the bad HP drivers. In the second part, I go over 5 different ways to reinstall new HP drivers. (Video is below this paragraph)
UPDATE: 10/28/20 – I’ve added multiple new instructions to #8 Workarounds / Fixes section.
UPDATE: 10/27/20 – HP has posted a new community knowledge article on the issue with full install instructions.I posted the link in section 8 (Workarounds/ Fixes).
An issue like this is normally something that I would be immediately reporting on, but I was away from my Mac until late Saturday. I started to investigate the issue as soon as I returned. One thing I noticed right away was that the signature was valid! Howard Oakley covered this issue extensively since Friday. I asked Howard to check the signature again and sure enough he confirmed it was good. I figured it was case closed, and shelved the article.
NOPE!
Many users are still reporting printing problems. This time around though, it seems like a different cert issue. Plus users are reporting errors from other frameworks and services like scanning.

From Apple
Safely open apps on your Mac macOS includes a technology called Gatekeeper, that’s designed to ensure that only trusted software runs on your Mac.
support.apple.com/en-us/HT202491
For this particular error the article says this.
If macOS detects that an app has malicious content, it will notify you when you try to open it and ask you to move it to the Trash.
If Gatekeeper detects a problem with an application, it will give you this warning.
5. User Reports
The first reports came in on Friday October 23rd 2020.
I spent a while with Apple Support, Something this morning (10/23/20) broke the HP printing drivers framework on Catalina OS 10.15.7. They have received many calls with different items related to HP informing it will damage your computer, My printer does not print. I have a Laserjet 4200 with all kinds of options (envelop feeder, etc.) It is a vicious circle – Apple says to call HP as they need to provide the drivers, I have not been able to speak to anyone at HP that can help.
More reports started to roll in on the Apple Discussion Forums.
I’m getting the exact same popup, I know its not malware. because it’s part of my printer software downloaded from Apple Mac store but apple not updated my software a few OS’s ago and have Malwarebytes Premium installed for a few years now. I have not downloaded anything in past 24-48 hours. somehow I think its a MacOs compatibility issue apple will need to address
After over a year with having two HP printers in use, this morning, 10/23/2020 after startup of my Mac, I started getting this same pop-up. In searching for a cause, I saw where to look in the ~/Library/LaunchAgents folder and indeed this file was put there yesterday, 10/22/2020, at 10:00 AM: com.hp.devicemonitor.plist I deleted this file from the ~/Library/LaunchAgents folder, which resolved the pop-up box from coming up, however now my HP Envy 7640 printer will not work. Our other HP printer does continue to work. Hoping Apple will come up with suggestions on this.
Thomas Reed started to see a bunch of support tickets due to this problem.
We're seeing a significant influx of support cases where users are seeing macOS identify what appear to be legit processes as malware, exactly what is being reported here:https://t.co/vPojXGukzp
We've got quite a few cases continuing to come in to support on the HP software issue. Even though the cert has been un-revoked, some folks still see the issue. Folks are either angry that we didn't detect the "malware" or because they think we're detecting it erroneously. ?
We unintentionally revoked credentials on some older versions of Mac drivers. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer.
When issues like this have come up in the past, I always attempt to replicate the issue. When I got back late Saturday night, it seemed like the issue was resolved. I checked the certificate/signing and it looked good! The cert was showing as invalid earlier in the day. After this, nothing I could do could reproduce the issue on my home HP printer. This might mean that new users might not have the issue. It’s still unknown at this time.
I was able to get the error on a network printer using a spooler driver. I would get the same error. After clicking OK, the print que would stop with an error.
It looks like this issue can no longer be reproduced. From what we know so far, you would have needed to have your Mac online from October 23-24th and already have the printer drivers installed. If you try the same thing now, printing will be fine.
8. Investigation.
Let’s try to figure out what happened here.
1st Issue – (Friday – Late Saturday)
Howard was able to check the HP Utility.app using is home built free app ArchiChect. This is what the application reported.
The application signature check has FAILED! The check reports that the certificate was REVOKED!
2nd Issue – Late Saturday, I ran the same check and this is what it reported.
Looks good right? I thought that HP had reissued the cert and everything was good to go!
I started to receive more and more reports saying that the issue was still NOT fixed.
Let’s take a closer look.
If we run the same check on one of the frameworks we get this
source=Unnotarized Developer ID
The same thing happens if we run the command manually on the HP Utility.app
1.Use AirPrint – AirPrint is the future of printing on macOS. (NO DRIVERS NEEDED!) If your printer supports AirPrint use it. For more info check out this link >
2. Let macOS install the correct driver for you! After deleting the hp folder and removing the printer. Plug in your printer in via USB. You will get a popup like this
macOS detects that it does not have the driver for this HP printer.
Click “Install” to let macOS attempt to find and install the HP printer driver.
macOS is auto installing the driver!
When the install is complete the printer will show up in System Preferences > Printers & Scanners! Simple as pie right ?
3.Uninstall and then reinstall HP drivers. This is also is a proven workaround.
1. Delete the /Library/Printers/hp folder
2. Delete Printer from System Preferences > Printers and Scanners
3. Install HewlettPackardPrinterDrivers.dmg from Apple (Link below)
