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.
I checked the release notes for 11.0.1 RC and 11.0.1 Final then compared them and did not find any differences.

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.

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.

Not anymore, you can just drag and drop the full Install macOS Install.app (or Windows iso or Linux .iso) over to this window to begin!
VMware Fusion Player 12 – Select Install Method
The next screen will let you select macOS installer.app file. You will normally only see the one that you just dragged over. In my case, I have already installed 10.14, 10.15 and 11.0. Click Continue.
VMware Fusion Player 12 – Select Install image
You will now see a final finish screen, before you start to configure the VM.
Finish of the VM setup wizard.
The next screen will tell you that VMware Fusion Player is creating installation media.
VMware Fusion Player 12 – Creating Installation Media
You will get a warning about running this VM machine with side channel mitigations enable. It says that side channel mitigations provide enhanced security but lower performance. You can change the settings when the VM is not running in the Advanced panel of the VM.
VMware Fusion Player 12 – You are running this virtual machine with side channel mitigations enabled.
The new macOS VM is booting to the installer! Once booted, it will be just like you booted into the recovery partition. All you need to do is select Install macOS to begin.
VMware Fusion Player 12 – Booting to the macOS Installer.
30 Minutes or so later you will be at the Setup Assistant Screen.
Congratulations! You’ve just built your first macOS virtual Machine!
Snapshots
One of the best features about having a macOS virtual machine is snapshots. You can build out a fresh OS and then take a snapshot before you make any changes to the system. Did the test not work? No big deal! Instead of reinstalling the OS to test again, just revert back to a previous snapshot! It’s literally that simple. You can access snapshots from the Virtual Machine menu bar item.
Snapshots!
Boot your macOS VM to Recovery Mode
Quick Way – sudo nvram "recovery-boot-mode=unused" && sudo reboot
If you need to boot the VM to macOS Recovery mode, all you need to do is edit the .vmx file located in /Users/youruserfolder/Virtual Machines/vmnamehere
Right on the file and then select “Show Package Contents”. Inside will be your vmnamehere.vmx file. Right click on that file and edit it with your favorite text editor. Add this line at the very end of the file and click save.
macosguest.forceRecoveryModeInstall = "TRUE"
Start up the VM an you will now be in recovey mode.
To boot back to macOS, open that same file and delete the line that you just added above and click save.
The final step is to delete the .nvram file in that same directory.
NOTE: 10/07/20
I am having trouble booting to recovery with Big Sur Beta, I’m going to run a few more tests. This works fine on 10.14 and 10.15.
MacOS Big Sur 11.0 -10.16 (20A4299v) Beta 1 was released today on June 22nd, 2020 at 2:00 CST right after the keynote.
macOS Big Sur 11.0 Patch Notes
Just like last year, the 11.0 beta 1 patch notes list is huge! The amount of detail is just what MacAdmins are looking for! Let me give you some stats from the 11.0 Beta 1 Patch notes document.
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)
If macOS Big Sur 11 beta is installed into the same APFS container as previous versions of macOS, system software updates can no longer be installed on the previous versions of macOS. (64411484)
Installing a new kernel extension requires signing in as an Admin user. During kernel extension development, every time a kernel extension is changed, it must be signed and notarized. In both cases, your Mac must be restarted to load the extension. (55068348)
If you updated to macOS Big Sur 11 beta from a previous version of macOS, Software Update might show “Unable to check for updates – Failed to download the documentation for the minor update. Please try again later”. (63158434)Workaround Below
Kernel extensions using certain deprecated KPIs no longer load. Refer to the support page. While macOS Big Sur remains in development, you can temporarily disable System Integrity Protection to allow these deprecated extensions to load. (55068348)
macOS Big Sur 11 beta improves system security by requiring an administrator password when a certificate trust settings change is made in the admin trust domain. Running as the root user alone is no longer sufficient to modify certificate trust. User trust domain settings continue to require confirmation by entering the password for the user’s account.
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 11.0 (20A4299v) Beta 1 Release Notes
I always post the full patch notes to this page to document them for you. The reason behind that is that Apple will usually just replace over the old patch notes so you are then unable to see what was fixed in the previous release.
Overview
The macOS 11 SDK provides support to develop apps for Macs running macOS Big Sur 11. The SDK comes bundled with Xcode 12 beta. For information on the compatibility requirements for Xcode 12 beta, see Xcode 12 Beta Release Notes.

Darwin kevent now allows non-parent processes to register for NOTE_EXITSTATUS, which delivers the same values as the wait() family of functions in the event data. Refer to the wait4() man page for more information. This event is subject to the following security checks:
The requesting process is allowed to send signals by sandbox restrictions.
The requesting process and the target process are running as the same user or the requesting process has root privileges. (58134463)
Known Issues
Installing a new kernel extension requires signing in as an Admin user. During kernel extension development, every time a kernel extension is changed, it must be signed and notarized. In both cases, your Mac must be restarted to load the extension. (55068348)
Remote panic dumps aren’t currently available. (57915324)
New in macOS Big Sur 11 beta, 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)
kmutil install might fail to build a development kextcache. (63772702)Workaround: Copy the release .elides to the locations of the development .elides:sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.development.elidessudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.kasan.elides sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.debug.elidessudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.development.elidessudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.kasan.elidessudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.debug.elides
Use only absolute paths with the --volume-root option of kmutil, and don’t use a trailing /. (63773848)
After removing a DriverKit extension, restart your Mac to complete uninstallation. (63995046)
Adhoc signed kernel extensions are displayed with a developer name of unknown in update dialogs and in Security preferences. (64215260)
Symbols exported by both xnu and Apple kernel extensions will change. Recompile your kernel extension with each update to macOS Big Sur 11 beta to ensure compatibility. (64262563)
Moving a kernel extension bundle out of /Library/Extensions might not completely uninstall it. (64331929)Workaround:
Remove the extension from /Library/Extensions.
Boot to macOS Recovery.
Run Terminal.
Enter the command kmutil invoke-panic-medic.
Restart your Mac.
Follow the prompt to open System Preferences and navigate to Security & Privacy.
Follow the prompt to restart.
An unexpected System Extension Updated alert for third-party kernel extensions which are included in macOS might appear. These include: Accusys, Inc., ATTO Technology, Inc., Areca Technology Corporation, CalDigit, Inc., HighPoint Technologies, Inc., Promise Technology Mobile Apps, and Other World Computing. (64337113)

Localization
Known Issues
Certain languages might exhibit clipped or misaligned layout. (63105445)
Certain languages might display unlocalized text. (63105674, 64040564, 64045718)
Some keyboard shortcuts might not work when running macOS Big Sur 11 beta in a language other than English. (63834383)
Location
Known Issues
Widgets have access to location information even if the NSWidgetWantsLocation key isn’t in their Info.plist. (61953645)
New APIs are available for using os_log from Swift as part of the os framework:
A new type Logger can be instantiated using a subsystem and category and provides methods for logging at different levels (debug(_:), error(_:), fault(_:)).
The Logger APIs support specifying most formatting and privacy options supported by legacy os_log APIs.
The new APIs provide significant performance improvements over the legacy APIs.
You can now pass Swift string interpolation to the os_log function.
Note: The new APIs can’t be back deployed; however, the existing os_log API remains available for back deployment. (22539144)
Mac Catalyst
Known Issues
Content Extensions require a temporary workaround. (57442394)Workaround: Add the following key/value pair to the NSExtension dictionary in the Info.plist: "NSExtensionContainingViewControllerClass" = "_UNNotificationContentExtensionViewController".
If Messages is launched immediately after logging into iCloud, a login window might be displayed unexpectedly. (56309057)Workaround: Relaunch Messages after a few minutes or try restarting your Mac.
You might be unable to type in the photo picker search field when attaching a photo. (60011306)Workaround: Click the search field, press the tab key, then click the search field again.
You might receive an alert that indicates the maximum number of pinned conversations has been reached. (62919406)Workaround: Pin the conversation using drag and drop instead of using a swipe action or quick action with Haptic Touch.

Known Issues
Safari might quit unexpectedly when opening the Start Page if Frequently Visited Sites are visible as thumbnails. (63945984)Workaround: Make the window wider, hide the sidebar, or Control-click on Frequently Visited Sites and choose View as Icons.
Security
New Features
macOS Big Sur 11 beta improves system security by requiring an administrator password when a certificate trust settings change is made in the admin trust domain. Running as the root user alone is no longer sufficient to modify certificate trust. User trust domain settings continue to require confirmation by entering the password for the user’s account. This change may affect you if one of the following is true:
You have written scripts which call /usr/bin/security add-trusted-cert -d ... as root.
Your process runs as root and calls the SecTrustSettingsSetTrustSettings function to trust a certificate.
Workflows that add trust settings in the admin trust domain, such as for an enterprise root certificate, may require modification if the user can’t authenticate as an administrator at the time settings are changed. (21855995)Workaround: Use Apple Configurator 2 to create and install a configuration profile containing your root certificate.
Spotlight
Known Issues
When quickly typing a search query in Spotlight, the result from a previous search might appear, then pressing return may create a wrong launch shortcut for subsequent queries. (64428836)Workaround: Type your query and click the desired result from the list that appears.
If you can’t find an application using Spotlight, launch the application at least once using Finder. (64463806)
SwiftUI
Known Issues
Disclosure groups in Forms might produce unexpected results. (64079102)
Nested disclosure groups generated by OutlineGroup might produce unexpected results. (64097731)
The SceneStorage property wrapper isn’t yet supported. (64414712)
A label used with a symbol image might appear misaligned. (60193698)
SystemExtensions
Known Issues
Driver extensions might not launch on-demand after installation. (51229724)Workaround: Disable System Integrity Protection, then launch Terminal and execute the following command before approving the newly installed driver: sudo touch /Library/DriverExtensions.
Touch ID
Known Issues
Touch ID might become unexpectedly disabled on Macs with a T2 Security Chip after installing multiple operating systems. (62608379)Workaround: Reset the SMC of your Mac.
Rebuilding against the iOS 14, macOS 11, watchOS 7, and tvOS 14 SDKs changes uses of GeometryReader to reliably top-leading align the views inside the GeometryReader. This was the previous behavior, except when it wasn’t possible to detect a single static view inside the GeometryReader. (59722992) (FB7597816)
MacOS Big Sur 11.0 – Updated Index of Need to Know Changes & Links
WWDC 2020 – macOS Big Sur 11.0
WWDC is here again! For the first time ever, Apple’s Worldwide Developers Conference will be 100% Virtual. MacAdmins everywhere are wondering what changes macOS Big Sur will bring and how deployment workflows will be affected. I hope to help you answer multiple question with this article. This year I will follow the same format as my previous MacOS 10.15 Catalina – Updated Index of Need to Know Changes & Links post. Be sure to check back frequently, I will keep you up to date with the latest macOS Big Sur 11.0 changes!
macOS Big Sur brings a refined new design, powerful controls, and intuitive customization options to the most advanced desktop operating system in the world.
Faster updates – Once macOS Big Sur is installed, software updates begin in the background and complete faster than before — so it’s easier than ever to keep your Mac up to date and secure.
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.
Updated Notification Center – A redesigned Notification Center puts all your notifications and widgets into a single, dedicated column. Notifications are automatically sorted by most recent, and redesigned Today widgets deliver information at a glance.
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.
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.
New 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. Just click the Control Center icon in the menu bar and adjust Wi-Fi, Bluetooth, AirDrop, and other settings — without opening System Preferences.
Signed system volume – macOS Big Sur introduces a cryptographically signed system volume that protects against malicious tampering. It also means that your Mac knows the exact layout of your system volume, allowing it to begin software updates in the background while you work.
Safari extensions on the App Store – An all-new extensions category on the App Store showcases Safari extensions with editorial spotlights and top charts, making it easier to discover great extensions from developers. All extensions are reviewed, signed, and hosted by Apple for your security.
Privacy information on the App Store – A new section on each app’s page on the App Store will help you understand the privacy practices of the app before you download it.9 It’s similar to the way nutrition labels help you understand what’s in food before you buy it.
Self-reported privacy practices – Developers self-report their app privacy practices on the App Store.9 See the types of data their app might collect — like usage data, contact information, or location — and whether that data is shared with third parties.
App Privacy is Displayed in a simple format – Just as nutrition labels are convenient and easy to read, an app’s privacy information on the App Store is displayed in a consistent, simple format.9 This lets you quickly and easily understand the app’s privacy practices.
