Big Sur 11.0.1 (20B50) Released to block install for 2013-2014 13-inch MacBook Pro Users.
Big Sur 11.0.1 (20B50) was released to block 2013 & 2014 13″ MBPro’s from installing the OS. This move looks to be related to the Big Sur install problems with these models.
UPDATE 12/14/20 – Apple has added the Mac-189A3D4F975D5FFC BoardID back to the newly released macOS Big Sur 11.1 Full installer! It looks like Apple has found and fixed the issue with the installer that was causing problems! This means that you can now download, install and reinstall Big Sur 11.1 on your 2013-14 13″ MacBook Pro again.
UPDATE 11/25/20 – If you attempt to install Big Sur on your 13″ 2013-2014 MBPro, you might get this error.
Installation of macOS could not continue. installation requires downloading important content. That content can’t be downloaded at this time. Try again later.
If you are wondering about the Big Sur Installer issue for the 2013 & 2014 13″ MacBook Pro users, I wrote about the situation earlier this week.
To review, if you have a 2013 or 2014 13″ MacBook Pro and attempted to install macOS Big Sur, it was possible that the installer could brick your Mac.
When I say “brick” I mean that it boots to a black screen and is 100% non responsive. You can’t boot to recovery, USB installers, reset the pram or SMC.
The only option for users is to bring it in for repair. The reports say that Apple is saying that the logic board needs to be replaced at a price over 500$. Even worse some are being told it’s a vintage product and they can’t parts. This is FALSE, Apple will keep stock of parts up to 7 years.
Vintage products are those that have not been sold for more than 5 and less than 7 years ago. Mac, iPhone, iPad, iPod, and Apple TV vintage products continue to receive hardware service from Apple service providers, including Apple Retail Stores, subject to availability of inventory, or as required by law.Apple.com – https://support.apple.com/en-us/HT201624
https://support.apple.com/en-us/HT201624
Hopefully Apple will cover the cost of the repair for free.
The solution for now? Release a new macOS Big Sur Installer that removes both models from the Big Sur compatibility list.
The link below shows the list of Big Sur compatible Macs
If you can’t install macOS Big Sur on certain 13-inch MacBook Pro computers from 2013 and 2014. Follow these steps if you can’t install macOS Big Sur on a MacBook Pro (Retina, 13-inch, Late 2013) or MacBook Pro (Retina, 13-inch, Mid 2014). When you install macOS Big Sur on these Mac models, the installer might say that the update cannot be installed on this computer, or your Mac might start up to a blank screen or circle with a line through it.
Apple.com
The most important part of this article is this line
“or your Mac might start up to a blank screen“
This is exactly what will happen to some users if they install macOS Big Sur on their 2013 or 2014 13″ MacBook Pro.
Let’s look at the other parts of the note.
“the installer might say that the update cannot be installed on this computer“
This is because both models have been removed from the new Big Sur installer compatibility list.
“or your Mac might start up to a blank screen or circle with a line through it“
This might happen if you make a new USB installer of Big Sur 11.0.1 (20B50) and attempt to boot to it.
Removed from the Big Sur Compatible List?
The macOS installer has a file inside called the distribution file. For this release it’s called 001-83532.English.dist.
Compatible Macs for install are listed in this file as BoardID for older devices and DeviceIDs for newer models. The boardID we are looking for is
Mac-189A3D4F975D5FFC
This BoardID is for the MacBookPro11,1 or the 2013 & 2014 13″ MacBook Pro.
I keep a database of all Mac BoardID and DevicesIDs here
You can see the list of supportedBoardIDs – Mac-189A3D4F975D5FFC was removed from 11.0.1 (20B50)
This means that (for now anyway) you will not be able to install macOS Big Sur on your 2013 or 2014 13″ MacBook Pro.
Will Apple fix this issue and add them back later?
Unknown at this time. It’s possible that Apple will fix issue the Big Sur installer is causing to these models. They could then add the models back to the compatibility list later.
macOS Big Sur running list of install / upgrade problems.
This article is a running list of all known macOS Big Sur install / upgrade issues.
macOS Big Sur launched on Thursday November 12th, 2020. As with any launch of a product or software there will be issues. In the case of Big Sur, the problems started almost immediately. Users started to report download issues when trying to get Big Sur.
As the the week went by, more serious issues started showing up. If you are seeing a one of these issues, feel free leave a comment below.
Mr. Macintosh video that goes over some of the known Big Sur Install issues.
macOS Big Sur Install Issues Table of Contents
UPDATED 2/14/21 – List of macOS Big Sur Installation Issues.
1. Big Sur Full Installer.app Download Problems – “Installation Failed Error Occurred while installing the selected updates.”
2. Big Sur progress gets stuck mid installation – Black Screen with Apple Logo stuck or stopped progress bar
3. Big Sur Install failing and bricking some older 13″ MBPro’s – Installation fails and the Mac has a black screen – Will not respond to any startup commands.
4. Big Sur stuck in endless boot loop. – Some users are reporting after a good install the Mac is stuck in an endless boot loop.
5. Slowness after upgrade to Big Sur – Other have reported that their Mac is very slow after upgrading to Big Sur.
6. Reinstalling macOS Big Sur on Apple Silicon –
7. Big Sur Upgrade Error – An error occurred preparing the software update.
8. If you can’t unlock settings in System Preferences Big Sur 11.1
If more trending issues come in, they will be posted here.
1. Big Sur Full Installer.app Download Problems – “Installation Failed Error Occurred while installing the selected updates.”
UPDATE 11/27/20 – I’m still getting a bunch of people reaching out saying that they are still getting the error even after Apple fixed the issue! I have a fix for you via Hyram Hakkenbecker. You can download the full macOS Big Sur installer directly from Apple’s servers via Safari.
2. Big Sur progress gets stuck mid installation – Black Screen with Apple Logo stuck or stopped progress bar
This issue happens halfway through the Big Sup upgrade or install process. The Mac has already rebooted to the installer and is now on the progress bar. The problem is, something has gone wrong on the install and the progress bar gets stuck at a certain percentage and will never move again.
The progress bar looks to gets stuck at around 40% and will never move again. Below is a screen shot from MacRumors forum user plandersen.
Big Sur install Black Screen progress bar stuck.
What should you do if this issue happens to you?
1. First WAIT! Sometimes the install process takes time. If after a few hours pass and the progress bar has not moved go to the next step.
2. At this point, you have no choice but to power down. I know this sounds drastic, but you literally have no other choice. The good news is, this is also the fix. Many users have reported that this fixes the issue for them. After force powering down the Mac will come back up and and will boot right to Big Sur.
Out of all the reports, this one is the most serious. I do not throw around the “Bricking” term much, as it means that the Mac is usually DEAD. In this situation, if this issue happens to your Mac it will be non responsive.
The reports say that the install starts but after the reboot they get a black screen with nothing on it. Even if the user restarts they will still get the black screen. If they attempt to hold down option, Command R, Reset the Pram, SMC… etc nothing works. In this mode the Mac will NOT respond to any startup keyboard commands
Mr. Macintosh video going over the 2013-2014 13″ MacBook Pro Bricking Issue
Mr. Macintosh UPDATE video going over the 2013-2014 13″ MacBook Pro Bricking Issue
Affected Macs known so far.
13″ MacBook Pro from 2013-2014.
What should you do if this issue happens to you?
In my option, this issue is 100% on Apple to fix for users. If an update or upgrade causes a Mac to become unusable they need to fix it at no cost to the user.
Wait until a possible new fix comes in.
Wait for a Service Program that will cover this issue.
Bring your Mac into service. Apple so far is saying that you will need to replace the logic board. If they say it will cost you to fix the issue, ask for escalation. This issue is not your fault. A macOS update or upgrade should not BRICK your Mac!
(WARNING this is a last ditch attempt. Try at your own risk!) Try disconnecting the I/O board.
Reddit user maknell wrote an great write up covering the issue.
Other users have reported that after installing Big Sur, their Mac will be in an endless boot loop.
What should you do if this issue happens to you?
1. Try to boot into safe mode. Does the the Mac boot correctly? If so something installed on your mac is causing this issue. Maybe it’s an 3rd party application that has installed a Kernel Extension or a LaunchDaemon that is causing the issue.
2. Reinstall macOS
5. Slowness after upgrade to Big Sur – Other have reported that their Mac is very slow after upgrading to Big Sur.
I am starting to see a decent amount people say that after updating to macOS Big Sur from macOS Mojave or Catalina has caused a bunch of weird issues including slowness. The slowness is all over the system, including opening apps, Apple Menu and system preferences just taking a long time to load.
What should you do if this issue happens to you?
Wait! It’s possible that spotlight search is currently indexing and can take some time.
If after a while the system is still slow, open up activity monitor and click on the CPU or Memory tabs. Are any apps or processes taking very large amounts of memory or CPU?
If so kill the process then check system performance.
Still having issues after checking everything? Backup your data and perform a fresh install. I have macOS Big Sur running on a bunch of Macs even all the way back to the 2014 model. They all run very well. Almost all of them had a fresh install. This might be the way to go.
6. Reinstall macOS Big Sur on Apple Silicon Mac = An error occurred preparing the update. failed to personalize the software update. Please try again.
If you try to reinstall macOS on your new M1 Apple Silicon Mac you will get an error. The issue requires a 2nd Mac to fix!
7. Big Sur Upgrade Error – An error occurred preparing the software update.
If you attempted to upgrade to macOS Big Sur and you did not have enough free space on your hard drive the upgrade will fail! This will also leave you in an upgrade install loop. Even worse, if you have Filevault encryption enabled you will be locked out of your data!
Mr. Macintosh Deep Dive full report of this issue + full walkthrough and fixes for multiple situations!
8. If you can’t unlock settings in System Preferences Big Sur 11.1
If you can’t unlock settings in System Preferences If System Preferences doesn’t accept a valid administrator password when you click the lock to make changes, try these solutions.

The Catalina 10.15.4 Update is causing kernel panics in some 16″ 2019 MacBook Pros.
Did you Install the 10.15.4/10.15.5 Update on your 16 Inch MacBook Pro 2019, only to get a Kernel Panic after you Wake it from Sleep? You are not alone.
UPDATE 7/09/20 – I have received word that the wake from sleep kernel panic issue is resolved in 10.15.6 Beta 4 GM (19G71a). If still have the issue and can test, please let me know.
UPDATE 6/25/20 – I have a few reports that Big Sur Beta 1 fixed the issue, but for others they can still reproduce the problem. I would not recommend installing Big Sur as your main OS. You can install it in a 2nd container or external hard drive for testing. If Big Sur fixes the wake from sleep crashing issue, comment below or let me know!
UPDATE 6/8/20 – I am looking further into the 10.15.5 reports. Looks like this is the common error “Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOGraphicsFamily.”
UPDATE 6/03/20 – I am seeing new reports that the 10.15.5 Update has not fixed the issue for some users. Others are saying that after installing the 10.15.5 Update that they are no longer seeing Kernel Panics after waking from sleep. Additional reports are saying that the issue is worse after installing the 10.15.5 Supplemental Update.
UPDATE: 5/18/20 – It looks like 10.15.5 Beta 4 fixes the wake from sleep kernel panic issue. I have received multiple emails, tweets and article replies confirming that Beta 4 has fixed the issue for them. I would like to take the time to thank you for all of your individual reports. When I can’t reproduce the issue, I rely on you to provide critical feedback. THANK YOU!
UPDATE: 5/15/20 – I am starting to get some reports that the 10.15.5 Beta 3 & 4 fix the issue. Did you try the latest beta and find that it fixes the issue? Let me know!
UPDATE: 5/7/20 – macOS Catalina 10.15.5 Beta 4 (19F83c) was released today.I have not received any reports that Beta 3 fixed this issue. If it has please let me know. Apple did not mentioned this issue in any of the 10.15.5 Beta Patch Notes.
UPDATE: 4/29/20 – macOS Catalina 10.15.5 Beta 3 was released today.I am getting word that Beta 3 includes a possible fix for the wake from sleep issue. If you install Beta 3 and it fixes your issue, please let me know!
UPDATE: 4/16/20 – macOS Catalina 10.15.5 Beta 2 was released today. Did this update fix the issue for you? I am also looking for users who reverted back to 10.15.1, 10.15.2 or 10.15.3 to see if that fixed the issue?
Main Article
As soon as the 10.15.4 Update hit, reports started to pop up of wake from Sleep Kernel Panics on the 16″ MacBook Pro. Does this situation sound familiar to you? If so you have a great memory! I tracked a very similar issue that was caused by the 2019-004 Mojave and High Sierra Security update back in July of 2019.
I am seeing reports from users that this issue is happening again. This time around it is affecting macOS Catalina, specifically the 10.15.4 Update on the 2019 16-Inch MacBook Pro.

1. Affected Mac Models
Usually we have multiple different Models that are affected, but this time the issue looks to happen only one model.
So far I have not seen any reports. If you have reverted back and that fixed the issue for you, please let me know. Also let me know if you reverted back and you still have the issue.
7. This has happened before. Wait a few days before installing updates.
This is not the first time Apple has pulled an update. They pulled High Sierra and Sierra 2019-002 Security Update this past March. It’s a good idea to wait at least a few days before you update.
8. Does Apple Know about this issue? Are they working on a fix?
Apple does know about the problem. Engineering is currently investigating the issue. This information comes from MacAdmins who have a Enterprise Support Ticket in with Apple.
Hopefully we get a 2nd Supplemental Update that fixes the issue soon.
Some Intel GPU Only Based MacBooks Airs are Freezing / Crashing while using Video Conf apps like Zoom After installing the 2020-002 Security updates.
After Apple Released the 2020-002 Security Updates, some users started to report that their Mac would would freeze up when using GPU Hardware Accelerated apps or video.
UPDATE 05/26/20 – Apple has just released the 2020-003 Security Update for macOS Mojave 10.14 and High Sierra 10.13. Please let me know if the new update fixes the issue for you!!!
UPDATE 05/18/20 – On Friday I tested Zoom client v4.6.8 on a 2017 MacBook Air with 10.13.6. I experienced a freeze & 5 different app crashes on a multi user meeting. Today I installed 2020-003 Beta and did not see a single crash for over 6 hours on the same meeting. The 2020-003 Security Update is looking really good, but I still would like to see more confirmations. If you installed 2020-003 Beta and it fixed the issue for you , please let me know. I am hoping the update is released tomorrow or sometime this week!
UPDATE 4/29/20 – Today Apple released the Developer Beta version of 2020-003 Security Update for Mojave and High Sierra. I am trying to find out if it includes a fix for this issue. I will update you as soon as I have more information.
UPDATE 4/28/20: The consensus amongst users is upgrading to Catalina fixes the issue. The only problem with this is, some users have reported other GPU related weird issues in 10.15.4. Sometimes the system will freeze for a few seconds in Finder, Safari or performing other tasks. The good news is, even if the Mac does freeze (only for a few seconds) it will not require a hard power down. With that said, you could upgrade to Catalina and not have any of the above issues! If you are cautious, it might be better to wait for an update from Apple.
UPDATE 4/08/20: As the update is installed on more Macs, reports continue to come in. Apps like Illustrator and Animate from the Adobe Creative Cloud Suite are now causing freezing A MacAdmins User who has a ticket in, says Apple is aware of the issue and is actively working on a fix.
UPDATE 4/03/20: MacAdmins User Bollman decided to test the latest Zoom installer (4.6.9) and has not had any crashes for 6 hours. I loaded up (4.6.8) 3 times to confirm the crashes and gather additional logs. Then I updated to Zoom 4.6.9 and have not had any crashes for over an hour. I added this new information to the work around section below.I can’t explain this as the Zoom update patch notes only mention updates to fix the installer issues brought up by Security Researchers.
UPDATE 4/02/20: New reports are still rolling in. As each new report rolls in with a confirmed .gpuRestart log I will add that application to affected list below. The issue might not be only related to Video Conference Apps. Some users are seeing the issue with anything that is related to Hardware Accelerated Video.Full screen video, video in Safari, or YouTube.
I reported on a similar issue in August of 2019 when the macOS Mojave 10.14.6 Update started to cause Kernel Panics if you used the Built In FaceTime Camera.
This article has seen a big uptick in traffic as of a few days ago. Then I started to receive emails from users who were having their Mac freeze up after installing the Security Updates. After that the reports started to come in on MacAdmins Chat.
In this article, I will give you you an overview of the issue. In the end, I will show you a few workarounds that might work until Apple releases a fix.
Let’s dive right in and see what’s going on here.

If you have the issue on other Macs like the Mac Mini or older Macs, please do not hesitate to Contact Me.
3. User Reports.
The first report came in just two days after Apple released the Security Updates.
Anyone have issue with Zoom 4.6.7 for the Mac running on 10.14.6 where the use of the internal camera causes it to crash.
The next day more detailed reports started to roll in.
We’ve seen hard crashes on macs running 10.13.6 with latest security update (17G12034) and latest zoom version 4.6.8 (19178.0323). So far, 4 out of 80 machines with this combination of OS and zoom. What’s more in common with these machines is that they are MBA 2015 (non-retina). Anyone else seeing problems with latest security update on 10.13.6?
After doing this job for many years, I get an sense when things are starting to become an issue. It was not until this post came in on the following Monday.
For those running 10.15.4 (or latest 10.14/10.13 Security Update 2020-002 update) on the following hardware, can you try starting a zoom video conference (possibly may happen with other video conference software)? do you experience a hard crash?
After Balmes posted this, it was enough for me to take a closer look. Sure enough, users have started to report the same issues.
4. What is the Issue? The Mac will Freeze up requiring a hard shutdown.
UPDATE 04/01/20: After posting the article, I am getting a ton of reports that this issue is not just Video Conference Apps. Users are saying the Freeze / Lockup issue happens when using GPU Hardware Accelerated Video. This could be full screen video based activity.
How does the issue start? All you need to do is use some type of Video Conference Software that has multiple users with video enabled.
Once in the meeting the affected Mac can freeze up within one minute!
After the Mac Freezes, it will become 100% non responsive. The screen will freeze up and you will not be able to force quit. The only thing you can do is force power down the Mac.
5. .gpuRestart Freeze / Crashing Log Report
After you power up the Mac again, macOS will say that it was shut down due to a problem. At this point you need to look at the log to find the .gpuRestart log file.
UPDATE 04/02/20: To get the .gpuRestart log to show up, you have to let the Mac say on the frozen screen for at least a few minutes.
/Library/Logs/DiagnosticReports
You can also do a quick search by running this command
sudo ls -lah /Library/Logs/DiagnosticReports | grep .gpuRestart
Or use the Console.app, select “System Reports”.
A look at the console app and a few 2017 MacBook Air .gpuRestart error log files.
Application exampleGoogle Chrome He - Slack Helper (GP - zoom.us
Graphics Hardware exampleIntel HD Graphics 6000 - Iris Pro 6100
Signature example 803 - 802 - 806
6. Software that can cause the Freezing Issue
The following software can cause your affected Mac to freeze up. Below is a list of confirmed applications with a confirmed .gpuRestart freeze.
Zoom.us
Slack
Webex
Teams
Skype
BlueJeans
FaceTime
Sublime Text
Google Meet
Google Hangouts
Adobe Creative Cloud apps
Illustrator & Animate
VMWare Fusion
Spotify Helper
AnyDesk
ScreenConnect
Visual Studio Code
NOTE: Some of the new reports say that this happens when running the Video Conference Software from a Chrome Browser.
7. This time around the issue CAN be reproduced
I am able to reproduce this issue. If you would like to see what happens all you need to do is setup your Mac with the following.
2015-2017 MacBook Air
10.13.6 High Sierra with the 2020-002 Update installed.
Install zoom.us
Join any zoom meeting with multiple active users with their camera activated.
Join with Computer Audio. You can activate your own video or not does not matter.
Wait
Within about 1-5 min the MacBook Air screen will completely freeze and become unresponsive. You will need to hard power it off.
UPDATE 04/01/20: I was able to ssh into one of the MacBook Airs that was frozen. You can run commands like top and others. I attempted to force quit zoom.app and that did not change anything. I also tried to kill the loginwindow no go. Finally I attempted to restart the device with sudo reboot , I got the message that the ssh connection was closed like it was going to reboot but it didn’t.
8. Why rolling back with Automatic Update Snapshots will NOT work.
You might think, what if I roll back to a previous version of Mojave before the Security Update? In the past, this might have worked as the Update or security update is supposed to take an automatic tmutil localsnapshot before installing the update. If something went wrong you could boot to recovery and restore from that snapshot taken just before the update.
In this case that will not work because Update Snapshots are no longer working since 10.15.3!
Most issues like this have some type of workaround. Sometimes a workaround is found by accident or after hours of testing. This time around a few users on MacAdmins Slack have reported the following workarounds.
UPDATE 4/02/20: We are now hearing that Apple Support is recommending that users upgrade to macOS Catalina 10.15.4 to fix the issue. I can’t confirm if this fixes the issue but after looking at a large amount of .gpuRestart logs, I have not seen one from 10.15.4 yet. Many users are writing to me that after updating to 10.15.4, they are not having the freezing issue anymore.
UPDATE 4/03/20: For users who are having the freezing issue when using the Zoom.app, update to the latest version (4.6.9) and you should not see any more crashes.
Disable Zoom’s “Enable hardware acceleration for receiving video” option in the application video preferences. Scroll down and then hit the advanced button.
If the issue is happening in Chrome, some users found success with turning off Use hardware acceleration when available in Preferences > Advanced> System .
Use Firefox instead of Chrome when joining a browser based conference meeting.
Use conferencing in a browser instead of the application. An example of this is zoom. If you cancel out of the constant prompts to download the zoom.app, you will finally get an option to “Join Meeting with your Browser”
If you find any other workarounds please Contact Me
10. 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.
11. Conference Software Freezing Issue Links
I created a MacAdmins Chat Channel to disccus the issue.
Bollman – MacAdmins Slack User who did a ton of testing. He also spun up a zoom meeting room where we could all test.
bp – MacAdmins Slack User who’s post get me to take a closer look.
vplc – MacAdmins Slack User who was able to get me info and logs
Georgia – MrMacintosh Reader who was able to quicly answer a bunch of questions along with logs and a sysdiagnose.
Apple Engineer – Who jumped on the issue almost immediately after being invited to the #conf-freezing-issue chat. Gathered logs and FB and Enterprise Support Tickets to help get attention on the issue.
Everyone who emailed me, shared information in Slack, DM’d me or shared my article. Without your help I wouldn’t have been able to put all this information together.
This worked for some users but stopped working early in 2017. It’s possible that Apple disabled the old way with a firmware update.
The old command was
sudo nvram BootAudio=%01
The new command is
sudo nvram StartupMute=%00
BONG!!!!!!!!
I can’t believe it. You have to understand the emotions of a true Mac fan hearing a brand new 16″ MacBook Pro producing the startup chime. The startup chime is something that has been around since 1984. To say the chime is iconic, would be an understatement to any Mac Fan.
I tested this on at least 5 different MacBook Pro’s with different BridgeOS and T1 firmware versions.
I did find a difference, the T1 Macs have the same sound as the 2017 Macbook Air and 2016 Macbook. (The final Mac Laptops to have the sound enabled by default). The T2 sound is different, it sounds a little deeper.
I would love to find out this was a hidden easter egg for 4 years!
Was this nvram value recently added? Was it hidden in plain sight for almost 4 years? I would really like to find out. The first sighting of this seems to be a Reddit Thread from 2/20/20.
Mac models from early 2016 and earlier make a chime sound when they start up. Mac models from late 2016 and newer don’t have a startup chime, with the exception of MacBook Air (13-inch, 2017).
List of Mac BoardIDs, Model Identifiers & Machine Models.
Every Single Mac Board ID from 2006-2021 + M1 Apple Silicon DeviceIDs
This page will be updated with the latest list of Mac BoardIDs, Model IDs and Machine Models. Apple started to document attributes like ModelID on the page below but stopped after 2017.
Most BoardID’s are scattered all over the web but are not all in one updated page. I started with the version Intel based version and will update when new BoardID’s are introduced.
Can I upgrade or downgrade macOS on my Mac?
I wrote an article including every Intel Mac since 2006. The list includes the lowest and highest macOS version that you can install on your Mac.
The macOS installer.app uses the boardID value to figure out if the Mac Model is supported when the user starts the install.
You can find this list inside the macOS installer.app. Look for the InstallESD.dmg After you mount the DMG navigate to /System/Library/CoreServices/PlatformSupport.plist
Inside this plist you will find the list of logic board ID’s that installer supports.
How do I find the Mac BoardID?
To find your BoardID use this command.
ioreg -l | grep -i board-id
The output should read like this
"board-id" = <"Mac-942C5DF58193131B">
How do I find the Mac DeviceID?
To find your T2 DeviceID use this command. HT @eholtam for the command.

DeviceID & ModelID
The macOS Big Sur installer is now checking T2 Macs for the DeviceID attribute. Hat Tip #1 goes to @rickmark who maintains the main DeviceID list here. Help us fill in the blanks! Hat Tip #2 goes to @grahamrpugh who found the new code in Big Sur.
// Next compare T2 devices against the list of supported deviceIDs. … // For legacy hardware T1 and older, we use boardIDs

8. Xserve – (2006-2009)
I almost forgot about Xserve. How could I forget about one of my favorite most reliable Macs ever created? The Xserve was introduced on May 14, 2002. The First Generation was based on a G4 Processor. The 2nd Generation was based on the G5 and the 3rd and final Generation was based on Intel’s Xeon Processor.

10.14.6 Update Causes a Kernel Panic When Using the Built-In FaceTime Camera.
NEW UPDATE: 4/08/20 – I am getting multiple reports that users are having issues applications that use Hardware Accelerated Video with the latest 10.14 and 10.13 2020-002 Security updates. The system will 100% freeze up during video conference, video or heavy app usage and you will have to hard power down. I posted all the new information about the freezing issue in a new article here – https://mrmacintosh.com/2020-002-update-causes-some-macs-to-freeze-up-while-using-vid-conf-apps/
FINAL UPDATE: 1/22/20 – Multiple users have contacted me to let me know that the latest macOS Mojave 10.14.6 Security Update 2019-002 (18G2022) has fixed the issue for them! The T2 BridgeOS version is 17.16.12551 or newer.
UPDATE: 10/03/19 – I am hearing from readers and commenters that Zoom has confirmed that this issue is fixed in macOS Catalina 10.15. This could very well mean that we will not get a fix for Mojave. 🙁
After Apple released the 10.14.6 Update, some users of 2019 & 2018 15″ MacBook Pros started to report Kernel Panics when using the Built-In FaceTime Camera.
I reported on a similar issue about a month ago when the 2019-004 Security Update for High Sierra and Sierra started causing a Kernel Panic after waking from sleep.
In this article, I will give you the lowdown of the issue. In the end, I will also give you a workaround until Apple releases a fix.
If you are interested in the 2018-004 Security Update Wake from Sleep issue you can read my report Below.
If you have the issue on a 2018-2019 13″ MacBook Pro/Air Please do not hesitate to Contact Me.
3. This issue does NOT affect most 10.14.6 users.
I tried time and time again to reproduce this issue. Having both a 2018 and 2019 15″MacBook Pro for testing, I figured that I would be able to reproduce the issue. Having FaceTime.app open for hours and using Zoom Conference call for 4 hours, produced zero crashes. This could be a clue as to an additional cause on the reported users computers, but I’m not sure.
4. Kernel Panic Reports
What do the Kernel Panic Reports look like? Looking over the report it looks like BridgeOS is crashing. Below is a sample report.

5. Why rolling back will NOT work.
You might think, what if I roll back to a previous version of Mojave like 10.14.5? In the past, this might have worked! It will NOT work when the issue is caused by BridgeOS. Apple has made it impossible to roll back the version of your T2 BridgeOS.
After you updated to 10.14.6, your BridgeOS was also updated. If you try to reinstall 10.14.5, this version will still work but the newer BridgeOS will still be installed. This is also why if you got your MacBook Pro replaced at the Apple Store, the issue could STILL be happening to you.
The only way you could get this to work is if you got ahold of a 10.14.5 system on BridgeOS version 16.16.5601 or lower.
6. Built-In FaceTime Camera
The crash ONLY happens when you use the MacBook Pro Built-In FaceTime Camera. It does not matter what you do. From the many reports that I have looked through, the crash could happen the very second you activate the camera or 2 hours after. Most of the reports seem to be from 10min to 1 hour of use.
7. Camera Software that causes the KP’s
The following software can cause your Mac to Kernel Panic
FaceTime.app
WebEx
Zoom
Slack
Google Hangouts
Skype
Teams
gotomeeting
BlueJeans
You get the idea, basically ANY application that uses the Built-In FaceTime Camera.
8. Workarounds
Most issues like this have some type of workaround. Sometimes a workaround is found by accident or after hours of testing. This time around a few users on the Apple Discussion Forums found at least one workaround.
Plug in an additional Web Camera. This could be a USB Web Camera or even a monitor with a built-in camera like the Apple 27″ ThunderBolt Display.
You don’t even have to use the secondary camera. For some reason with the second camera plugged in reports say that you can use the built-in FaceTime Camera without crashes. Found by user edgonz305
Run a Windows Fusion VM with Skype in that VM. The problem does not occur using integrated camera. This is not a solution for everyone, but for me it works better than using an external camera. Additional workaround from OaSOakover
You can prevent the crashes by just disabling video on the meeting. (This one is pretty obvious if you don’t need to use the FaceTime Cam)
macOS Catalina Beta may fix the issue. Reported by Commenter Dave!
9. Will Apple fix this issue? 10.14.6 Supplemental Update #3 ?
With the end of support coming up fast for Mojave, will Apple fix this issue? I think the answer is YES. This is coming from reports that Apple DOES know about the issue and is still investigating. My guess is that Apple will release one final Supplemental Update to fix this.
If you or any of your users are having this issue, please contact Apple Support.
Zoom Response -“We found it not only influences ZOOM but also FaceTime, Skype and other Camera involving Apps, we are still working with Apple to fix it but currently as a workaround, please turn off your video when joining ZOOM meetings or use external camera by USB.”

Today Apple Released Multiple Hardware Updates to it’s NoteBook Line.
The Mac Lineup has seen multiple hardware updates so far in 2019. The trend continues today with the July 2019 Hardware Updates. Today we have two updated Macs and two discontinued Macs.
2019 Entry-Level 13″ MacBook Pro
When released the 13″ Non Touch Bar MacBook Pro was supposed to be an affordable way to get into the MacBook Pro line. The model did not come with a Touch Bar or Touch ID. After it was released, two hardware refreshes passed and it never gained the T2 Security Chip. That all changes today with the new updated model. The new features are listed below.
8th-generation Intel Core quad-core processors
Touch Bar
Touch ID
T2 Security Chip
Still 2 ThunderBolt 3 Ports
Same Base Price of $1,299
The price is pretty important here because, you get all the features above yet the same price of the previous model that did not have Touch ID, Touch Bar or the T2.
Apple today also updated the MacBook Air today after redesigning it in late 2018. The 2017 Model that was still for sale was finally discontinued. The 2017 Model carried on since late 2010.
Gained True Tone Display
Lowered Starting Price to $1099
2017 Model that was still for sale finally discontinued.
So long 2010-2017 MacBook Air! I really believe that this model was one of the greatest notebooks Apple has ever created.
I really liked the 12″ MacBook. It was super light and very portable, yet it lacked two things that would have made it a winner. I feel if it had Thunderbolt 3 and a 2nd port it would have sold a lot better. It’s too late for that now since it’s now dead. So long 12″ MacBook!
Lowered Internal SSD Cost Across Mac Line
Users have long complained about the SUPER high prices of Apple’s internal storage upgrades. Well today Apple has lowered the price for SSD Storage across the following models.
1TB SSD Upgrades have dropped by $200
iMac
MacBook Pro
Mac Mini
2TB Upgrades have dropped by $400
MacBook Pro
Mac Mini
4TB Upgrades have Dropped by $1400
MacBook Pro
This was a MUCH needed change as the prices for SSD storage did not even come close to current market prices.
UPDATE: I added links to the bottom of this article that will let you run a script to find your 2015 Mbp’s.
In some 15-inch Mid 2015 MacBook Pro units, the battery may overheat and pose a fire safety risk.
If you have a Mid 2015 15″ MacBook Pro, you need to check the serial number against Apple’s Battery Recall Database ASAP! Affected models are as follows.
MacBook Pro (Retina, 15-inch, Mid 2015)
MacBookPro11,4 (2.2 GHz)
MacBookPro11,5 (2.5 and 2.8 GHz)
From September 2015 and February 2017
Apple’s Recall Check Website
As soon as the press release was sent out this afternoon a new recall check website was launched so you can check to see if your 2015 MacBook Pro is affected.
Battery Recall Check Website
You can then enter in your serial number to check if your Mac is affected.
This serial number is one of the affected units with a recalled battery and MUST be replaced ASAP
As you can see above this MacBook Pro has a battery that “may pose a fire safety risk”. You need to get this MacBook Pro into service ASAP.
Replacement Process
Choose one of the service options below to have your battery replaced. In all cases, your device will be sent to an Apple Repair Center for service. Your MacBook Pro will be examined prior to any service to verify that it is eligible for this program. Service may take 1-2 weeks.
Contact Apple Support to arrange mail-in service via the Apple Repair Center.
If your Mac is NOT affected you will see this message below.
Your MacBook Pro is safe!
What do I do if my company or EDU has HUNDREDS of 2015 Macbook Pros to check?
I have good news for you! I have reached out to my Apple Account Mangers and they let me know that you can send them a list of serial numbers. They will then check the list against the battery recall database and return you the findings.
MacAdmin Scripts
JamfNation Forum users have put together a few scripts that can help you if you have a large list.
