Safari 14.0 + Mojave 2020-005 Security Update Causing Major Problems!

MrMacintosh.com - Mojave 2020-005 Security Update is Causing Major Problems for users.
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.

mrmacintosh.com/10-14-6-supplemental-update-safari-14-released-to-fix-previous-issues/

UPDATE #7 – 9/30 1:30PM – Apple just pulled both problematic updates!

  • Pulled from the update catalog
  • 1. Safari 14.0 – Released 9/16 – 001-50026
  • 2. Mojave 2020-005 Security Update – Released 9/24 – 001-50026
  • Added to the update catalog
  • 1. Safari 13.1.2 – Released Today – 061-98246

This is Apple’s acknowledgment of the issue.

Anyone who has not installed the updates will now be safe. This also means that we should be getting an official fix!!!

Stay tuned!

9/29

UPDATE #6 – 9/29 2:00PM – I’ve expanded the softwareupate --ignore section.

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.

1. Mojave 2020-005 Security Update Problems

What are the reported problems with this update?

  • 1. Memory issues – Reports of large increases of memory usage = no free memory and a large amount of compressed memory.
  • 2. Slow boot & High fan speed
  • 3. System slowness / stalling in finder
  • 4. New local user can not be created through Users & Groups.
  • 5. Migration assistant crashes to login window when started.

1. Affected Safari & macOS Build Versions

This issue affects the following Safari & macOS Build Versions.

  • Safari 14.0 – September 16th, 2020
  • Mojave 10.14.6 Security Update 2020-005 (18G6032) – September 24th, 2020
  • No reports so far of this happening on macOS High Sierra 10.13.

2. Affected Mac Hardware

Past problems would only happen with certain hardware models. Not this time, if you installed the Mojave 2020-005 Security Update on a compatible Mac you might have problems.

3. How can I tell if my Mac is affected by this issue?

Very simple, just open up the terminal.app and run softwareupdate -l

If you get this error your Mac is affected.

Class AMSupportURLConnectionDelegate is implemented in both /System/Library/PrivateFrameworks/EmbeddedOSInstall.framework/Versions/A/EmbeddedOSInstall (0x1130cec58) and /System/Library/PrivateFrameworks/OSPersonalization.framework/Versions/A/OSPersonalization (0x112f31358). 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.

sudo softwareupdate --ignore "Security Update 2020-005"

After running this command you should see this

Ignored updates:

(

    "Security Update 2020-005"

)

Now run softwareupdate -l to confirm that you don’t see the update.

You can reset ignored updates by running this command

sudo softwareupdate --reset-ignored

Good thing we still can use this command. If you would like to read more about how Apple is taking this option away read the link below.

mrmacintosh.com/10-15-5-2020-003-updates-changes-to-softwareupdate-ignore/

5. How to Reproduce – Install Order

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.

MacRumors User Earl Urley

More reports started to roll in on the Apple Discussion Forums.

On September 24th Sep, after performing the security update (2020-005), I immediately noticed ram problems. Has anyone had the same problem?

Apple Discussions Forum User DoctorAudioLinks

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.

Apple Discussions Forum User RestonMacGuy

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.

MacRumors Forum User Minipudding

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.

mrmacintosh.com/10-15-3-combo-security-updates-are-not-creating-backup-snapshots/

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.

  1. Reboot to recovery. Hold down Command R
  2. Once in recovery select “Restore from Time Machine Backup”
  3. On the next screen select “Macintosh HD”. If your Mac is filevault encrypted you will be asked for your password.
  4. On the next screen, if you have a snapshot available it will look like this.
MrMacintosh.com - Automatic Update Snapshots to save the day!
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.

  1. Upgrade to Catalina. This was recommended by Apple Support. If don’t want to upgrade to Catalina yet, scroll down to option #2.

2. Reinstall (Not Erase) macOS Mojave 10.14.6 (18G103)

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.

7. If you are seeing this issue, please let Apple know.

The only way to let Apple know that this is a big issue is to file a FeedBack Report. AppleCare Call or an Apple Enterprise Support Ticket.

This will help Apple Prioritize the issue and get it resolved ASAP!

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.

mrmacintosh.com/catalina-10-15-7-update-accountsd-using-400-if-using-icloud-mail/

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.

Let’s take a look at the macos Catalina 10.15.7 update changes.

What’s New in the 10.15.7 Update Mr. Macintosh video.
10.15.7 Update = accountsd process using 400%+ CPU if using iCloud Mr. Macintosh Video.

Catalina 10.15.7 Update Changes

What’s New in macOS Big Sur 11 Beta 8 (20A5374i)?

Today Apple released macOS Big Sur Beta 8 (20A5374i) to Developers

UPDATE 9/23/20 – Beta 8 Issues

  • Big Sur Beta 8 does not have a full installer, hopefully we will get one when Beta 9 hits in a week or two.
  • No changes or additional notes to Screen Recording controls, it was noted in Beta 7 that we would get some sort of MDM controls for this for standard users.
  • Active Directory login is not working in Beta 8 after an upgrade. Was working fine in Beta 6 and 7.

You can take a look at my Beta 7 article, it has a list of current standing issues that might not have been fixed in Beta 8 yet.

mrmacintosh.com/whats-new-in-macos-big-sur-11-beta-7-20a5374g/

MacOS Big Sur 11 Beta 8 (20A5374i) was released on September 22nd, 2020 only 7 days after Beta 7! MacOS Catalina had 11 beta releases including the gold master, so we are getting close to release. Beta 8 is very small and only includes one noted fix in the developer notes. I am still waiting to see if any changes are listed around screen recording or if we get a full installer. I will update as soon.

During the Big Sur beta release cycle, only the current beta patch notes are available. When a new beta is released the previous patch notes are overwritten. I compare both sets of release notes so I find the changes.

If you are having issues getting Beta 8 to show up in Software Update, take a look at my Big Sur Beta troubleshooting article. – mrmacintosh.com/big-sur-11-beta-not-showing-up-in-software-update-troubleshooting/

General

Known Issues

Important

macOS Big Sur 11 beta 5 is not currently supported for iMac (Retina 5K, 27-inch, 2020). If you encounter an installation issue on iMac (Retina 5K, 27-inch, 2020), you need to reinstall macOS Catalina. Hold down the power button to force restart, and then press Command-R immediately after turning on your Mac. Then, follow instructions to reinstall macOS Catalina from Recovery.

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)

AirDrop

Known Issues

  • You might be unable to use AirDrop if System Integrity Protection is enabled. (67033173)

App Store

Resolved in macOS Big Sur 11 beta 5

  • StoreKit symbols are now accessible when importing StoreKit and SwiftUI in the same file. (66337479)

AppKit

Apple Security Bounty

  • macOS Big Sur 11 beta 5 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.

EndpointSecurity

Resolved in macOS Big Sur 11 beta 5

  • Auth type events such as an ES_EVENT_TYPE_AUTH_EXEC leak kernel memory no longer cause your system to become unresponsive. (65750498)

Final Cut Pro and iMovie

Known Issues

  • You’re currently unable to capture video using either the built-in camera or external devices. (63528489)
  • The application might unexpectedly quit when using the Import Media window. (65543216)Workaround: Drag media from Finder to import it.

Installer and Software Update

Known Issues

  • You might be unable to update macOS Big Sur 11 beta 5, if Secure Boot is set to No Security. (63434409)
  • 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 will reveal 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.

Resolved in macOS Big Sur 11 beta 5

  • APFS containers with non-default allocation block sizes are now supported for installation. (64312561)

Kernel

Known Issues

  • The command kmutil inspect returns an error on Apple silicon Mac computers. (65804541)Workaround: Use kmutil dumpstate or pass explicit paths to collections using kmutil inspect -A /Library/KernelCollections/AuxiliaryKernelCollections.kc.development

Key-Value Observing

New Features in macOS Big Sur 11 beta 5

  • Key-Value Observation removal facilities now employ deterministic bookkeeping methods. Cases that would have produced hard-to-diagnose crashes, especially those where KVO signals problems accessing deallocated observer pointers or observers associated with incorrect objects, now produce an exception pinpointing which observed object needs a missed removeObserver(_:) call, and by which observers. This exception was previously thrown as ‘best effort’ when KVO could detect the problem; the new deterministic bookkeeping allows it to be thrown for all cases where removeObserver(_:) is needed.The improved determinism also allows improved Swift API handling. Instances of NSKeyValueObservation, produced by the Swift NSObject.observe(_:changeHandler:) method, take advantage of integration with this bookkeeping so they now invalidate automatically when the observed object is released, regardless of how the object implements its KVO behavior. This applies to all usage of this API in macOS 11 Big Sur beta, including on processes built with previous versions of the SDK, and eliminates certain classes of crashes that sometimes required using the legacy API instead. (65051563)

Markup

Resolved in macOS Big Sur 11 beta 5

  • Edits made using Markup are now saved. (64908822)

Messages

Known Issues

  • Keyboard navigation to move focus between controls isn’t currently available. (63987810)

Safari and Webkit

Known Issues

  • Applications that present modal UI in UIWebView delegate callbacks or that use JavaScript alert, confirm, and prompt might experience crashes under _WebThreadLock(). (64239727)

Spotlight

Known Issues

  • If you can’t find an application using Spotlight, launch the application at least once using Finder. (64463806)

SwiftUI

Known Issues

  • ProgressView generic type signature has changed, adding the currentValueLabel generic parameter. This change does not 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 5 or later to resolve this issue.

New Features in macOS Big Sur 11 beta 5

  • Color can be converted to and from CGColor. The ColorPicker can also now be configured with a binding to a CGColor. (56939085)
  • Introduced ToolbarItemGroup as a convenient way to place multiple items in a specific location of non-customizable toolbars. (64178863)
  • ProgressView now supports adding a secondary “current value label” that describes the current progress level of the task. Use the label to describe the overall task, and the currentValueLabel to provide more specific details about the progress of the task. (63580200)
  • FileDocument and have updated protocol requirements:
    • Their initializer requirement now has a single FileDocumentReadConfiguration parameter that the fileWrapper and contentType can be read from.
    • Their write() functions that were expected to write to an inout FileWrapper parameter are now fileWrapper() functions that return a FileWrapper instead.
    • The Document-based app templates in Xcode have been updated to reflect this change in API.
    • Source compatibility with the previous requirements will eventually be removed. (65146043)

Resolved Issues in macOS Big Sur 11 beta 5

  • Images that contain multicolor symbols will now adapt to color appearance. (63726389)
  • Text(_ style:) no longer truncates. Text now has flexible width inside a widget. (60588299)
  • Placeholder-style redacted Text that has a lineLimit(1) modifier applied now appears as expected. (66346107)
  • SwitchToggleStyle and LinearProgressViewStyle can now be tinted on macOS. (62906674)
  • NavigationLink and NavigationView behave more consistently on macOS: NavigationLink’s selection isn’t incorrectly reset to nil due to selection changes; programmatic selection and deselection of a NavigationLink appears as expected. (63791979)
  • Applying a fixedSize() modifier to a TextEditor will now fix its size to the size of its content. (64855179)
  • Placeholder-style redacted Text that has a minimumScaleFactor modifier applied now appears as expected. (66242496)

Third-Party Apps

Known Issues

  • 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

Users & Groups

Resolved in macOS Big Sur 11 beta 5

  • If you select the option to delete it, the home folder is now deleted when removing a user. (65558783)

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().

Widgets

Known Issues

  • When set to My Location, the Weather widget might display weather for a different location. (66338250)

Resolved in macOS Big Sur 11 beta 5

  • When indicating a significant change in temperature for the next day, the Weather widget now correctly displays temperatures in Fahrenheit. (65061840)
  • The weather widget now displays data in a timely manner. (66014597)

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.

Catalina 10.15.6 Supplemental Update (19G2021) Released!

MrMacintosh.com - Catalina 10.15.6 Supplemental Update (19G2021) Released!
macOS Catalina 10.15.6 Supplemental Update (19G2021) Released!

macOS Catalina 10.15.6 Supplemental Update is now Available.

Today Apple released the 5th Supplemental Update for macOS Catalina. This time around, the fix is for memory leaks with virtualization software . You can read more about the issue from Howard Oakley and a VMware engineer. The other fix has to do with the brand new 2020 5k 27-inch iMac.

Build Version Number Mistake?

The Build version for this update is (19G2021). Normally a 4 digit end number on a macOS build version number means that it’s a “Forked” installer. A “Forked” installer means that it will ONLY install on brand new hardware from Apple. A perfect example of this is when Apple released the new 2020 iMac. It includes brand new hardware drivers that the previous builds of macOS didn’t include. To resolve this, Apple will release a full installer that has this new hardware included but will only install the new hardware. When a new dot release comes out, Apple will unify the installer so it can be install on any Mac including the new hardware. Tidbits has a great article that explains Apple build versions. The only problem is, the article does mention macOS hardware specific or forked build versions.

Below is a list of all the forked hardware specific installer build versions that Apple released for 10.15.

19B2093, 19B2106, 19D2064, 19E2269, 19F2096, 19F2200, 19G2005 & 19G2006

Below is a list of standard releases.

19B88, 19A603, 19A602, 19A583, 19C57, 19D76, 19E266, 19E287, 19F96, 19F101 & 19G73

Why did Apple give this unified installer a forked build version number (19G2021) ?

UPDATE: – Erik Gomez @Contains_ENG mentioned that 4 digit daily builds are common near the end of an OS release. Looking back at 10.13 and 10.14, this is true only when Apple starts to release 2020-001 type security updates. For example when Big Sur is released, Apple will stop working on bug fixes for Catalina and will only send out security updates. After the switch the build version usually makes the jump to 4 digits. I guess Apple decided to get a head start this year.

Unified 10.15.6 Full Installer

The good news about this update is that includes the 2 new BoardIDs for the 2020 iMacs. This means you do not have to keep a separate installer if you have any of the new iMacs in your fleet. The new installer (19G2021) will work on them.

The Catalina 10.15.6 Supplemental Update Includes the following fixes.

macOS Catalina 10.15.6 supplemental update includes big fixes for your Mac

  • Fixes a stability issue that could occur when running virtualization apps
  • Resolves an issue where an iMac (Retina 5k, 27-inch 2020) may appear washed out when waking from sleep.

How To Install macOS Big Sur on VMware Fusion and Parallels Desktop.

Like clockwork, Apple delivers a new macOS every year. MacAdmins need to start testing the new OS right way. Running the new os in a virtualized environment is the way to go. The only problem is, sometimes the new OS will not install on the current version of VMware Fusion or Parallels Desktop.

Many MacAdmins have already jumped in to find out if macOS Big Sur will install on Fusion or Parallels. The initial report is that a straight install will NOT work. The macOS Big Sur installer presents this error to you.

The operation couldn't be completed. (BIErrorDomain error 3.)

Updates – 7/08/20

VMware Fusion Tech Preview 20H2 is now available!!

blogs.vmware.com/teamfusion/2020/07/fusion-big-sur-tech-preview.html

Direct link to the download – https://bit.ly/get-fusion-tp

Be sure to check out the workarounds section. Below is one example.

Big Sur guests may log out unexpectedly and/or display a black screen when clicking an invisible icon in the upper right corner of the display.

  • Workaround: There is no workaround at this time, we are continuing to investigate

VMware just posted this update.

Tech Preview of Fusion is coming in early July.

2. Notes

  • VM Tools – Even though Big Sur to works on Parallels and Fusion, do not install VM tools yet. Some reports say that after installing VM tools the system boots fine YMMV.
  • Parallels Tools – VM can get stuck on a black screen after the reboot. Would recommend not installing the tools.
  • Parallels – VRAM seems suck at 3mb, causing slow response.
  • Keyboard & Login Issues – Getting reports that VM’s are not accepting certain keys. 1, 2, t and y keys. You need to hold FN key to make them work.

3. Creating a bootable Big Sur ISO

The instructions below will create a bootable Big Sur ISO.

hdiutil create -size 12G -fs hfs+ -volname macOSInstaller -type SPARSEBUNDLE /Users/Shared/macOSInstaller

hdiutil attach /Users/Shared/macOSInstaller.sparsebundle
"[path to]/createinstallmedia" --volume /Volumes/macOSInstaller --nointeraction

hdiutil detach /Volumes/Install\ macOS\ Beta

hdiutil makehybrid -o /Users/Shared/macOSInstaller /Users/Shared/macOSInstaller.sparsebundle

# Now create a macOS 10.15 VM with a 50 GB disk i Fusion

# Connect the virtual optical drive to /Users/Shared/macOSInstaller.iso

# Boot and install (you may need to "adjust" the disk Disk Utility to recognize the full capacity)

4. Creating a bootable Big Sur .dmg

Below is a script that Nathan Worster wrote to create a bootable macOS Big Sur Beta dmg.

5. How To Install Big Sur 11 on VMware Fusion

Requirements

  1. Disk Size – 50-60GB+ Virtual disk size required (40GB Standard size does not seem to work)
  2. Clean install vs Upgrade – A Big Sur Upgrade from Mojave or Catalina is the easiest path. Usually all the values that I mention below are already set, so you have a clear path.
  3. Mac Compatibility – Note if the hw.model is not supported for Big Sur the install will fail. You can fake it by setting a different hw.model and board-id. Be sure to check the compatibility list here.

Install Instructions

If you would like to use the same values from your Mac you can set this attribute. HT @lamw for the simplification!

  • smbios.reflectHost = "TRUE"

You can also manually set the the required values. The example below = 16-inch MacBook Pro.

  • hw.model = "MacBookPro16,1"
  • board-id = "Mac-E1008331FDC96864"
  • serialNumber = "serialnumberhere" (For DEP Enrollment testing)

To get the values you can run the following commands

  • sysctl hw.model = Model
  • ioreg -l | grep board-id = BoardID

VMware Fusion Links

Notes

Using Fusion 11.5.5 on Mojave 10.14.6, modifying the vmx file was unnecessary. I did a fresh install of Catalina 10.15.4 in a new VM, copied the macOS Beta installer to the VM, and ran the installer. It installed and booted fine. Note that I did not install the VMware Tools to the VM prior to installing macOS Beta. I had a prior Catalina VM with the Tools installed, and upgrading to the macOS Beta resulted in failures at the login screen after the Beta upgrade. So do the Beta upgrade on a fresh Catalina install and it should work fine (at least from 10.15.4).

Please note, if I added ‘board-id.reflectHost = “TRUE”‘ to the .vmx, the Fusion refused to boot the VM with an error that the vmx file is corrupted.

6. How To Install Big Sur 11 on Parallels Desktop

  • 1. Create a new VM by installing a fresh copy of 10.15 Catalina
  • 2. Do not install Parallels Tools
  • 3. The install requires at least 80gb or more
  • 4. Install beta profile
  • 5. Download Beta
  • 6. Set the following values set under Hardware > Boot Order > Advanced Settings > Boot Flags.
  • 7. Create a 2nd admin account. (this can help with login problems after the Big Sur install. Some users are saying that they can’t login with the original account. If that happens, login with the 2nd account.)
  • devices.mac_hw_model="MacBookPro16,1"
  • devices.smbios.board_id="Mac-E1008331FDC96864"

Keep in mind, both examples above are from a 2019 16-inch MacBook Pro. You can get the correct hardware values by running the following commands.

  • sysctl hw.model = Model
  • ioreg -l | grep board-id = BoardID

Try to install Big Sur. If that doesn’t work, try the instructions below.

Parallels Desktop Links

A big Hat Tip goes out to MacAdmin User @jacob for his instructions.

  • Used devices.mac_hw_model="MacBookPro14,3" and devices.smbios.serial="REAL_SERIAL" to make a 10.15 VM match my host for these values.
  • Used createinstallmedia to target an empty 12GB .dmg on the host
  • Mounted the .dmg as a disc to the 10.15 VM. 
  • Booted directly to the Installer disc (change boot order in Parallels).
  • Erased the disk as APFS in 10.16 Recovery
  • Initiated install (disconnected “disc” after first reboot)

7. How To Install Big Sur 11 on ESXi

William Lam @lamw aka virtuallyghetto.com wrote a great article on how to get macOS Big Sur working on ESXi.

virtuallyghetto.com/2020/06/macos-10-16-big-sur-beta-1-on-esxi.html

Did the listed steps work for you?

MacOS Big Sur Beta is still brand new! We will all be learning a bunch over the next few months.

Software Update
For increased security, major releases of macOS are not hidden when using the --ignore flag and the softwareupdate command starting with macOS 10.15.5. A major release is defined as one which receives a name, such as macOS Catalina.
Starting with macOS 10.15.4, major releases of macOS can be deferred for up to 90 days using MDM.

More on this here – mrmacintosh.com/10-15-5-2020-003-updates-changes-to-softwareupdate-ignore/


networksetup Command
Starting with macOS 10.15.5, the networksetup command behaves differently when run as a standard user versus an admin user. Standard users can do the following:
• 1. Read various network settings
• 2. Turn Wi-Fi power on or off (networksetup -setairportpower en0 on)
• 3. Change the Wi-Fi access point (networksetup -setairportnetwork en0
ExampleWiFiAP)
Other network settings can no longer be modified by standard users via networksetup.
For admin users, networksetup will continue to behave as it has in previous releases of macOS, provided System Preferences > Security & Privacy > Advanced… > “Require an administrator password to access system-wide preferences” is unchecked (which is the default state). If it is checked, admins will be bound by the same constraints as standard users when
using networksetup.
