This database will contain download links for macOS Big Sur full Installer pkg files (InstallAssistant.pkg). This file is the same full installer that you would download directly from the App Store for Intel and Apple Silicon M1 Mac Computers. The InstallAssistant.pkg is stored on Apple’s servers and contains the full “Install macOS Big Sur.app”. Once downloaded, all you need to do is install the pkg and the full installer of Big Sur will be in your applications folder. This change was made when Apple revised the full installer for Big Sur. The InstallAssistant.pkg is not available for Catalina or Mojave.

InstallAssistant.pkg?

The InstallAssistant.pkg is just a standard package that includes the full macOS Big Sur installer.app. All the pkg does is install/move the app to your applications folder. Let’s take a closer look.

MrMacintosh.com macOS Big Sur 11.2.3 via SUS Inspector — macOS Big Sur 11.2.3 via SUS Inspector

I am using SUS Inspector to view the full installer for macOS Big Sur 11.2.3. You can see the InstallAssistant.pkg file listed. You can also see the direct download path from Apple’s servers. The link does not last forever. For example, the download link for beta full installers only seem to last for a month or so.

Production links last a little longer. For example 11.2.1 is still available but 11.2 is not. This database will be updated when a new full installer is released.

Thank You

Have you sent over version information to me? THANK YOU!

A big thanks to Eric Holtam @eholtam. When I need to verify something in SUS, he always lends a hand!

Also thank you Hannes Juutilainen @hjuutilainen for creating SUS Inspector. This is a top 5 app for me!

What’s New in macOS Big Sur 11.1 RC Release Candidate (20C69)?

Today Apple released macOS Big Sur Beta 11.1 RC (20C69) to Developers

UPDATE 12/14/20 – macOS Big Sur 11.1 final is live! I just posted a new article that goes over all of the changes and new information that you need to know!

https://mrmacintosh.com/whats-new-in-the-macos-big-sur-11-1-update-20c69/

MacOS Big Sur 11.1 RC or Release Candidate was released on December 10th, 2020. We can expect the final version of 11.1 will be released very soon. The release comes one week after Big Sur 11.1 Beta 2. The Release Candidate brings support for AirPods Max, Apple’s new over-ear headphones. New features were also added to Apple TV, Apple News, App Store, iPhone Apps on M1 Macs, Photos and Safari.

Release date = Monday December 14th (Possible due to Fitness+ launching that day and requiring the latest versions)

Big Sur 11.0.1 RC2 Full Installer = “An Error occurred installing macOS”

MrMacintosh.com - macOS Big Sur 11.0.1 RC2 Full Installer.app error = "An Error occurred installing macOS" — macOS Big Sur 11.0.1 RC2 Full Installer.app error = “An Error occurred installing macOS”

When you attempt to install or upgrade on a T2 Mac, you will get the error “The bridgeOS update doesn’t satisfy the given minimum version requirement.”

UPDATE 11/12/20 – This article is for yesterday’s Big Sur BETA install problem. If you are having problems downloading the new Big Sur update or full installer I have a new article on the issue. It’s for the Installation failed an error occurred while installing the selected updates error.

mrmacintosh.com/big-sur-installation-failed-an-error-occurred-while-installing-the-selected-updates/

Almost immediately after macOS Big Sur 11.0.1 (20B28) was released, I started to see reports of install issues. This was only happening on T2 Macs that need a BridgeOS update. A BridgeOS update is included and required with almost every combo, delta and full installer upgrade or install. Below is the 11.0.1 RC2 Install error.

An error occurred installing macOS. You can try again to complete the installation.

Mr. Macintosh video that goes over the issue.

The problem is the new production Software Update Catalog URL does not have the needed BridgeOS update yet.

The problem comes down to the installer looking to the new production SUS url. Apple just made the production SUS catalog available. The new URL is

New Big Sur Production SUS URL =

https://swscan.apple.com/content/catalogs/others/index-11-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog

Big Sur Beta SUS URL =

https://swscan.apple.com/content/catalogs/others/index-10.16seed-10.16-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog

The production URL does NOT include the required BridgeOS update needed for the Big Sur RC2 installer to continue.

The BridgeOS error from install.log

This is the error that you will get.

This is what the new Big Sur 11 production SUS looks like right now.

MrMacintosh.com - Big Sur 11.0.1 RC2 SUS Production url. — Big Sur 11.0.1 RC2 SUS Production url.

Notice how the Big Sur 11.0.1 RC2 BridgeOS update is not showing up. This is why you are getting the error.

Below is what the Big Sur DeveloperSeed Catalog looks like.

MrMacintosh.com - Big Sur 11.0.1 RC2 SUS Beta url. — Big Sur 11.0.1 RC2 SUS Beta url.

The Big Sur DeveloperSeed catalog has the 11.0.1 RC2 BridgeOS update!

Now that we know what the problem is, what can we do about it?

Set the SUS server to the DeveloperSeed SUS URL.

To resolve this issue we can use the nvram binary to set the SUS catalog to the correct one that has the BridgeOS update that we need.

sudo nvram IASUCatalogURL=https://swscan.apple.com/content/catalogs/others/index-10.16seed-10.16-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog

You can use sudo nvram -p to view all the nvram settings.

NOTE! When you are done with the upgrade, don’t forget to remove the value!

sudo nvram -d IASUCatalogURL

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.

macOS Big Sur 11.0.1 RC 2 – Beta 3 Release Candidate (20B28) Release Notes

General

Known Issues

Important

Updating to macOS Big Sur 11.0.1 Release Candidate 2 from previous versions of macOS might take significantly longer than expected. Data loss could occur if the update is interrupted. (59101197)

Accessibility

Known Issues

You might be unable to pair certain braille displays using Bluetooth. (69794099)Workaround: Connect these devices using USB instead.

AppKit

See AppKit Release Notes for macOS Big Sur 11.

Installer and Software Update

Known Issues

When updating from macOS Big Sur 11 beta 2 to macOS Big Sur 11 beta 3 or later, you might be offered an unexpectedly large download rather than an incremental software update. (65753086)Workaround: Under the “Another update is available” text, click the “More info…” link. This reveals the incremental update where you can click the Install Now button.
You might need to adjust Energy Saver settings so your Mac doesn’t go to sleep while preparing to install macOS Big Sur 11.0.1 Release Candidate 2. (63166401)
If macOS Big Sur 11.0.1 Release Candidate 2 is installed into the same APFS container as previous versions of macOS Catalina 10.15, system software updates can no longer be installed on the previous versions of macOS. (64411484)Workaround: Update the previous version of macOS Catalina to 10.15.6 or later.

Kernel

Known Issues

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.

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!

What’s New in macOS Big Sur 11.0.1 Beta 1 (20B5012d)?

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
New wallpaper + Mojave wallpaper was removed
New Startup chime for 2013-2017 Macs = Same as T2 chime
AirPods Update Bug – Moves volume mixer to Right or Left
Software Update Button = Downloading Beta 10 full installer for some users.

Installer and Software Update

Known Issues

When updating from macOS Big Sur 11 beta 2 to macOS Big Sur 11 beta 3 or later, you might be offered an unexpectedly large download rather than an incremental software update. (65753086)Workaround: Under the “Another update is available” text, click the “More info…” link. This reveals the incremental update where you can click the Install Now button.
You might need to adjust Energy Saver settings so your Mac doesn’t go to sleep while preparing to install macOS Big Sur 11.0.1 beta. (63166401)
If macOS Big Sur 11.0.1 beta is installed into the same APFS container as previous versions of macOS Catalina 10.15, system software updates can no longer be installed on the previous versions of macOS. (64411484)Workaround: Update the previous version of macOS Catalina to 10.15.6 or later.

Kernel

Known Issues

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 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries.

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 beta to ensure compatibility. (64262563)

Localization

Resolved in macOS Big Sur 11.0.1 beta

Certain languages no longer exhibit clipped or misaligned layout. (63105445)
Certain languages no longer display unlocalized text. (63105674, 64040564, 64045718)

Mac Catalyst

New Features in macOS Big Sur 11.0.1 beta

Optimized for Mac is a new option for Catalyst apps. When optimized for Mac, Catalyst apps use Mac controls, appearances, spacing, and true font metrics, and content is no longer scaled by 77%. A new constant, UIUserInterfaceIdiom.mac, has been introduced to support the new idiom. For more information on the new idiom and optimizing your Mac Catalyst app, see Choosing a User Interface Idiom for Your Mac App, and Optimize the Interface of your Mac Catalyst App — WWDC20.
When you deliver your iPad app on the Mac via Catalyst, your existing users on iOS no longer need to purchase your app a second time. In addition, you can manage the capabilities and App Store metadata of your app in one place.
Application preferences that include no items users can set are instead shown in the About box.

Known Issues

A ToolbarItem with automatic placement isn’t placed in the window toolbar. (63690384)
Select UIKit controls, control customizations, and methods throw exceptions when used in the Mac idiom. Unsupported controls and behaviors on macOS Big Sur 11 throw exceptions as follows:
- UIButton. addGestureRecognizer(_:) throws an exception if the button uses the macOS appearance. setTitle(_:for:) and setImage(_:for:) throws an exception for any state except UIControlStateNormal.
- UISlider. setThumbImage(_:for:), thumbTintColor, setMinimumTrackImage(_:for:), minimumTrackTintColor, setMaximumTrackImage(_:for:), maximumTrackTintColor, minimumValueImage, and maximumValueImage all throw an exception.
- UISwitch throws an exception when title is set in a non-Mac idiom view.
The button configuration for the action with UIAlertAction.Style.cancel has the key equivalent of escape.
Button configurations for actions with UIAlertAction.Style.destructive will be configured with hasDestructiveAction.
If you apply both preferredAction and UIAlertActionStyleCancel to the same action, preferredAction takes precedence. It’s not possible to have a default button with the escape key equivalent.
The system adds an Open Recent menu automatically to applications that support opening files. The menu identifier is UIMenuOpenRecent.
UISceneActivationRequestOptions has a new collectionJoinBehavior property. A scene collection is a group of scenes that display together. In Catalyst, this is used to add windows to an NSWindowTabGroup.
- The default placement is UISceneCollectionJoinBehavior.automatic and the new scene will follow system preferences for joining collections.
- Set the placement value to UISceneCollectionJoinBehavior.preferred to have the new scene attempt to join the collection that contains the requestingScene, or any compatible collection if requestingScene is not set.
- Set the value to UISceneCollectionJoinBehavior.disallowed to create a new collection for the scene, ignoring system preferences.
- The value to UISceneCollectionJoinBehavior.preferredWithoutActivating to add the new scene without deactivating the requestingScene. Otherwise this property behaves the same as preferred.

Network Extension

Resolved Issues

You must adopt the NETransparentProxyProvider API in your transparent proxy implementation in order for it to function correctly. (65228404)

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.

Resolved in macOS Big Sur 11.0.1 beta

DisclosureGroup’s isExpanded binding now works as expected in a List. (58820037)
The system now lazily evaluates List updates. (58820037)
Adding a Widget that uses a Text with dynamic Text.DateStyle presentations no longer causes Notification Center to quit unexpectedly. (70059211)

Third-Party Apps

macOS Big Sur 11 Beta 10 (20A5395g) Release Notes

General

Known Issues

Important

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)

AppKit

See AppKit Release Notes for macOS Big Sur 11.

Apple Security Bounty

macOS Big Sur 11 beta 10 is designated as qualifying for the 50% Apple Security Bounty bonus payment for issues that are unknown to Apple or reintroduced in this release. See Apple Security Bounty for more information.

Core Data

Resolved Issues

Core Data’s model editor no longer displays a blank Detail area for an Entity. (69472812)

Installer and Software Update

Known Issues

When updating from macOS Big Sur 11 beta 2 to macOS Big Sur 11 beta 3 or later, you might be offered an unexpectedly large download rather than an incremental software update. (65753086)Workaround: Under the “Another update is available” text, click the “More info…” link. This reveals the incremental update where you can click the Install Now button.
You might need to adjust Energy Saver settings so your Mac doesn’t go to sleep while preparing to install macOS Big Sur 11 beta. (63166401)
If macOS Big Sur 11 beta is installed into the same APFS container as previous versions of macOS Catalina 10.15, system software updates can no longer be installed on the previous versions of macOS. (64411484)Workaround: Update the previous version of macOS Catalina to 10.15.6 or later.

Kernel

Known Issues

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 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)
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)

Localization

Known Issues

Certain languages might exhibit clipped or misaligned layout. (63105445)
Certain languages might display unlocalized text. (63105674, 64040564, 64045718)

Resolved in macOS Big Sur 11 beta 10

Notes and Photos no longer quit unexpectedly if the system language is set to Greek. (69548692)

Mac Catalyst

Known Issues

A ToolbarItem with automatic placement isn’t placed in the window toolbar. (63690384)

Network Extension

Resolved Issues

You must adopt the NETransparentProxyProvider API in your transparent proxy implementation in order for it to function correctly. (65228404)

SwiftUI

Known Issues

ProgressView generic type signature has changed, adding the currentValueLabel generic parameter. This change doesn’t require any source changes, but will cause 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.
DisclosureGroup‘s isExpanded binding doesn’t work as expected in a List. (58820037)
Adding a Widget that uses a Text with dynamic Text.DateStyle presentations will cause Notification Center to quit unexpectedly. (70059211)

Resolved in macOS Big Sur 11 beta 10

Dynamically updating OutlineGroup content updates correctly. (58820037)
Standard menu items, such as Open Recents or Window menu items, are no longer missing from the main menu. (63998004)
High-contrast asset catalog images are correctly used by Image when in an environment with colorSchemeContrast == .increased. (65164844)
Xcode Previews no longer quit unexpectedly when previewing a view using FetchRequest. (65544435)
Scrolling a selected NavigationLink far offscreen no longer deactivates that link or dismisses its presented destination. (62092320)
Dynamic CommandMenu and CommandGroup constructions now update correctly on App state changes. (67735428)
You can now reorder a List using SidebarListStyle as expected. (66386684)
ScrollView now has a correct default scroll position when underneath the titlebar. (64319463)
A TextField that you are editing inside a selected List row now has correct text foreground colors. (68545878)

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().

6. Apple Silicon Recovery Options

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.

MrMacintosh.com - Apple Silicon Mac Startup Options — 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”.

MrMacintosh.com - Apple Silicon macOS Recovery — 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.

MrMacintosh.com - Apple Silicon Mac System 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.

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.

MrMacintosh.com - Apple Silicon Mac External USB Installer Boot — 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.

1. Revive = ?
2. Restore = ?
3. Reinstall macOS = Reinstall macOS Recovery / System Recovery / macOS

This will help with rapid deployment in lab / school situations.

MrMacintosh.com - Apple Silicon Mac Apple Configurator 2

14. Apple Silicon Security Policy

We know that an Apple Silicon Mac will have 2 Security modes.

MrMacintosh.com - Apple Silicon Mac Security Policy — 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.

MrMacintosh.com - Apple Silicon Mac per-OS Security Policy — 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.

MrMacintosh.com - Apple Silicon Mac Sharing Mode — Mac Sharing MOde replaces Target Disk Mode.

18. Apple Mac Mini Developer Transition Kit (DTK)

VMware Fusion Player 12 is FREE! Test macOS, Linux or Windows 10

VMware Fusion Player 12 is now free for personal use on the Mac!

Last month VMware announced VMware Fusion 12. The new version includes macOS Big Sur support for host and guest. VMware also announced that the Mac version is now FREE ($149 Normal Price) for personal use! Previously the Free VMware player was only available on Windows. You can use it to test macOS, Windows 10, or Linux. If you’ve always wanted to set up a macOS VM, now is the time. It’s never been easier to build a test VM, so let’s get started!

How To Register, Download, Install & Configure VMware Fusion Player 12 – Mr. Macintosh Video.

Create a New VMware Account.

VMware notes that the free version is available for the following situations.

Fusion Player offers a Personal Use License, available for free with a valid MyVMware account. Home users, Open Source contributors, students, and anyone else can use Fusion Player Free for Non-Commercial activity.
VMware.com

If you are one of those, head over to the registration site.

my.vmware.com/web/vmware/evalcenter?p=fusion-player-personal

MrMacintosh.com - Register your VMware account. — VMware registration page

Once registered you will see your license key, be sure to document this somewhere as you will need it when you install VMware Fusion Player.

If you didn’t and need to find your license key later, use this link.

my.vmware.com/group/vmware/evalcenter?p=fusion-player-personal&cmp=EMC-FusionPlayerEvalActivation&li=license

This link also has a download area to get the the 600MB .dmg installer.

Install VMware Fusion Player 12

Open the .dmg and install Fusion Player 12. NOTE: VMware Fusion 12 requires macOS Catalina or newer. Once complete, open the application and you will be prompted to enter in the license key.

When you first start VMWare Fusion you will get a Select Install Method Screen. In the past you needed to run through a bunch of steps to create a macOS Install .ISO file. 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!

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.

You will now see a final finish screen, before you start to configure the VM.

MrMacintosh.com - VMware Fusion Player 12 - Finish — Finish of the VM setup wizard.

The next screen will tell you that VMware Fusion Player is 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.

MrMacintosh.com - VMware Fusion Player 12 - You are running this virtual machine with side channel mitigations enabled. — 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.

MrMacintosh.com - VMware Fusion Player 12 - Booting to the macOS Installer. — 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.

Boot your macOS VM to Recovery Mode

Quick Way – sudo nvram "recovery-boot-mode=unused" && sudo reboot

To get back to macOS out just reboot!

Thanks for the tip Mike! More info here – https://mrmacintosh.com/boot-to-internet-recovery-recovery-partition-or-diagnostics-from-macos/

2. Long Way.

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.
