Today Apple released macOS Big Sur 11.1 (20C69) to the public.
MacOS Big Sur 11.1 was released on December 14th, 2020. The 11.1 update is the first major update for Big Sur. The release comes a few days after Big Sur 11.1 beta RC and is the same build number. Big Sur 11.1 also brings support for AirPods Max, Apple’s new over-ear headphones. New Features added to the following apps Apple TV, Apple News, App Store, iPhone Apps on M1 Macs, Photos and Safari.
UPDATE: 12/15 – 11:30AM
This version is the same BuildVersion as 11.1 Beta RC = (20C69)
softareupdate –fetch-full-installer is fixed! (Was broke in 11.0.1)
2013 & 2014 MacBook Pro 13″ Bricking issue looks to be fixed in 11.1! The BoardID for this model was added back to the full installer.
2020-006 Security Update for Mojave & High Sierra + Safari 14.0.1
Security Updates 2020-006 for macOS Mojave 10.14 (18G6042), High Sierra 10.13 (17G14042) & Safari 14.0.1 are now Available.
With the release of macOS Big Sur, Apple also released Security Updates for both macOS Mojave and High Sierra. Catalina was issued a 10.15.7 Supplemental Update to address the same security issues in 2020-006.
NOTE: Apologies for the tardiness of this article, Big Sur and Apple Silicon really took my attention away. I didn’t forget about everyone who asked me when my Security Update article would come out. I will always test the update out first so you don’t have to deal with issues.
You can read more about the 10.15.7 Supplemental update below.
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.
How to Restore BridgeOS on a 2018+ T2 Mac using Apple Configurator 2. How to Boot your Mac into DFU Mode
With Apple Silicon Macs, you can install macOS just like you can with iOS! I will show you how to boot your Apple Silicon Mac into DFU Mode so you can Restore macOS.
UPDATED 06/04/21
This article will go over how to restore macOS on your new Apple Silicon Mac. Your first line of defense for installing macOS on Apple Silicon should be macOS Recovery. But if for some reason you are having problems with that you can boot your Apple Silicon Mac with a Big Sur USB installer drive. I wrote an article covering all the changes to macOS Recovery here.
Order of that you should follow for reinstalling macOS on Apple Silicon.
1. macOS Recovery – Hold down the power button to enter the Boot Picker Menu (downloads macOS Big Sur over the internet 1-2 hours)
2. System Recovery – (Separate hidden partition – Will boot automatically if macOS Recovery is erased or damaged)
3. macOS Big Sur USB Installer Drive – External boot for macOS Installers is enabled by default on Apple Silicon – (Installs from USB 30-40 Min)
4. Apple Configurator 2 REVIVE option – This option will reinstall macOS Recovery if erased or damaged (retains user data on the hard drive)
5.Apple Configurator 2 RESTORE option – This option will Reinstall macOS Recovery, ERASE your hard drive and reinstall macOS (Fast install! 10 min)
Use macOS Recovery on a Apple Silicon M1Mac
Keep in mind, just like last time, some of the instructions for booting your Apple Silicon Mac are confusing. If you thought booting to DFU mode was a little difficult on T2 Macs… wait until you try on Apple Silicon. For one thing the ports used are the exact opposite of what was used on T2 Macs! Plus the process to get the Mac into DFU mode has changed! That’s why I’m writing this article, to better explain the instructions.

UPDATE 4/13/21 – New DEEP DIVE video on using Apple Configurator 2 to reinstall macOS on multiple M1 Macs.
UPDATE 3/17/21 – I’ve added a new video that shows you how to use Apple configurator 2 to install macOS on multiple M1 Macs.
UPDATE 1/14/21 – Apple has released Apple Configurator 2 Version 2.13.3, be sure to update. I’ve also added a new Apple Silicon Mac Mini M1 Video above.
UPDATE 11/18/20 –Apple has released Apple Configurator 2 Version 2.13.2! Make sure you update. If you are still running 2.13.1 or below you will get an error when you click the restore button.
UPDATE 11/17/20 –Added a new section #6 to explain the problem booting to DFU mode if your Apple Silicon Mac is on it’s factory firmware of 6723.41.11
This is a list of Apple Silicon Macs that this process is compatible with.
1. 2020 M1 13″ MacBook Pro
2. 2020 M1 MacBook Air
3. 2020 M1 Mac Mini
4. 2021 M1 24″ iMac
3. Setup and Cable Requirements before you begin.
You will need to meet the following requirements –
(The Host Mac will do the work and the Target Mac is the Mac you need to Restore)
1. USB-C Mac as the Host Machine.
2. The Host Mac must have at least macOS 10.15.6 and Apple Configurator 2.13.1 or newer installed.
3. Internet access on the Host Mac – “You may need to configure your web proxy or firewall ports to allow all network traffic from Apple”
4. USB-C to USB-C Cable – The white Apple USB-C Charge will work fine. (USB-C Cable MUST Support Power & Data). Apple notes that a Thunderbolt 3 to Thunderbolt 3 cable is not supported but I’ve tested it and it works fine.
5. The Host Mac can have the cable plugged in anywhere.
6. The Target Mac MUST have the USB-C Cable Plugged in to the Left Hand side USB-C port. For Laptops the port closest to the back of the Mac or screen) For the Mac Mini it’s the port closest to the ethernet port. (BOTH LOCATIONS ARE OPPOSITE of the T2 Mac BridgeOS restore locations!)
If you don’t meet all the prerequisites booting to DFU Mode or Upgrading macOS Firmware might fail.
4. Download Apple Configurator 2
Download Apple Configurator 2 app. Version 2.13.1 or higher is required.
If you do not have Apple Configurator 2, you can download it now from the Mac App Store with this link.
5. How to Boot your Apple Silicon Mac into DFU Mode
With all the startup keyboard commands you can issue a Mac, booting into DFU Mode should be pretty simple right?
NOPE! (x2 this time for Apple Silicon!)
You have to follow a very particular sequence to get this to work. I have attempted to find the exact way to get this to work every time. Even then sometimes the system will refuse to Boot into DFU mode.
Apple’s Instructions
You can find Apple’s instructions for booting into DFU mode here.
If these instructions do not work fo you continue below.
Press the power button.
While holding down the power button, at the same time press all three of the following keys for about 10 seconds:
The right Shift key
The left Option key
The left Control key
After 10 seconds, immediately release the three keys but continue to hold down the power button until it appears in Apple Configurator 2.Note: You won’t see any screen activity from the Apple notebook computer.

6. Which Firmware version is your Mac on?
Did you update your Mac to Big Sur 11.0.1 from 11.0 when it arrived? If you didnt the firmware will be
6723.41.11
To find the firmware version click the Apple icon > About this Mac > System Report.
Look for System Firmware Version.
If you are on Big Sur 11.0 and firmware version 6723.41.11 you will need to boot to the macOS Recovery selection screen first before attempting to boot into DFU mode.
If you updated your Mac to 11.0.1 and are running Firmware Version 6723.50.2 or newer you can follow the normal instructions. You can boot to DFU mode from power off instead of booting to the macOS recovery selection screen first.
7. My Instructions for the M1 13″ MacBook Pro & MacBook Air
It has proven difficult to get an Apple Silicon Mac into DFU mode. You could try Apple’s instructions above multiple times and STILL not get into DFU mode.
Once you have meet all of the pre requisites above, follow the instructions below to should get you into DFU Mode every time.
1. The Target Mac must be OFF to begin.
2.Hold down the Power button,RightShift, Left Control and Left Option keys for 10 Seconds (count 1 one thousand) then let go of every key except for Power . Keep holding down the power button for an additional 8 seconds until you get to 18 seconds total. If you count more than 20 seconds and don’t see the DFU icon, you will have to try the process again.
3. When the Target Mac is booted into DFU mode correctly, the host will show a big DFU icon in Apple Configurator 2.
4. After you see the DFU picture pop up on the AC2 Host Mac you can let go of the Power Button.
macOS recovery screen you can now start the DFU mode keyboard command process

1. Disconnect the power cord from the Mac Mini.
2. Plug USB-C/Thunderbolt cable into the USB-C port next to the ethernet port.
3. Plug the other end into the Host Mac.
4. While holding down the power button, connect the Mac Mini to power and continue to hold the power button for about 3-5 seconds
5. You should now see the DFU logo on the Host Mac.
9. Instructions for the M1 2021 24″ iMac
The 24″ M1 iMac (2021) instructions are to use the USB-C port is closest to the magnetic power port. The instructions are the same for both the 2 and 4 port version.

10. You made it! Apple Configurator 2 Steps
The hard part is now over. Now we can restore macOS on the Target Mac. When you first open Apple Configurator 2 the screen will look like this.
This is what you will see if the Mac is NOT booted to DFU mode.
This is what you will see when the MacBook is connected correctly with your USB-C cable and booted to the recovery selection screen.
Once your Mac is booted to DFU mode, you will see this screen on Apple Configurator 2. You are now ready for the next step.
When you see a big DFU icon when your Mac is properly booted into DFU Mode.
11. Download macOS ISPW file (Optional)
Apple Configurator 2 version 2.13.2 will automatically download needed IPSW file just like it can for iOS. Let’s say that you want to download the IPSW so you can restore multiple times for testing, you can get it from my database below.
Once you’ve downloaded the macOS IPSW file, you are ready for Restore.
12. Begin Apple Silicon macOS Revive / Restore
1. Revive Option
The revive option will ONLY reinstall macOS Recovery. Go to step 2 for Restore.
You are now ready to restore either macOS Recovery with revive by Clicking Actions > Advanced > Revive Device.
Right Click on the DFU icon – Select Advanced > Revive Device
Revive will reinstall macOS Recovery on your Apple Silicon Mac. This option retains user data.
2. Restore Option.
Restore will Reinstall macOS Recovery, ERASE your SSD hard drive and reinstall macOS.
2. Restore option – Reinstall macOS Recovery, ERASE your SSD hard drive and reinstall macOS.
You will now see a warning message. Do you want restore “MacBook Pro” to it’s Factory settings and latest firmware version?
Restore warning you the Restore process will erase your data and reinstall macOS
Click the Restore Button to begin. Step one will download the latest macOS IPSW Firmware file directly from Apple.
You can also drag the macOS IPSW File over to the DFU icon to begin the restore.
macOS Big Sur 11.0.1 IPSW Restore File – Drag this file over to the DFU logo to begin the restore.
After dragging the macOS 11 IPSW File over to the DFU logo you will get this pop up. You can select Restore to erase your drive and reinstall macOS. The process will only take about 15 minutes.
Ready to restore macOS, click Restore to begin.
Reinstalling macOS Big Sur from the IPSW file.
Step 2. Unzipping macOS
Step 2. Unzipping
Step 3. Installing macOS
Step 3. Installing BridgeOS
13. Finishing Up
If you would like to see more information you can click View and see a new activity window.
Apple Configurator 2 Activity window.
The entire process will only take a while. Most of the time is spent downloading the huge 13GB macOS Big Sur IPSW File. This is why it’s nice to keep the IPSW on an external hard drive or something. When you drag the IPSW File over to Apple Configuator 2, the restore will be super quick! Normally it only takes about 10 min!
When complete the Mac will automatically Boot up.
14. Can I Downgrade from an older version of macOS via IPSW Files?
The answer is YES, follow the link below for an explanation.
But only if the IPSW file is still signed by Apple. If Apple stops signing the IPSW file you will need to change the Boot Security to allow this. (Keep in mind Apple has not stopped signing any macOS installers yet, so we will see.)
15. Thanks
Hat tip goes out to macrumors forum user Nrwrit3r for the macOS Recovery menu workaround for older firmware!
NOTE 11/17/20! UNTIL I’M ABLE TO GATHER APPLE SILICON DATA I WILL LEAVE THE T2 BRIDGEOS TROUBLESHOOTING SECTION HERE.
I can’t get my Mac to boot into DFU mode. This is the toughest part of the whole process as I mentioned above. Keep trying the steps I listed above. Sometimes it takes multiple attempts to get his to work.
You can use System Information to see if the USB-C port lists your Mac in DFU Mode.
System Information showing a Mac plugged in booted to DFU Mode.
BridgeOS Restore Error 79- The OS Cannot be restored on this device. The Operation couldn’t be completed. (AMRestoreErrorDomain error 79 – Failed to handle message type StatusMsg) [AMRestoreErrorDomain – 0x4F (79)] – If you get this error it means that the BridgeOS update has failed and is unable to complete. The system will be unable to boot. When powered on the screen will be black. The Mac will have to be brought to an Apple Store for Service.
BridgeOS Restore Error – The OS Cannot be restored on this device. The Operation couldn’t be completed.
BridgeOS Restore Error 10 – The BridgeOS Restore failed! This is most likely because the host Mac was 1 or 2 OS Versions behind the Target Mac. The Host and Target Mac need to be on the same OS Version.
If your Target Mac is on 10.15, then your Host Mac needs to be on 10.15.
The OS Cannot be restored on this device.
The operation couldn’t be completed. (AMRestoreErrorDomain error 10 – Failed to handle message type StatusMsg) [AMRestoreErrorDomain – 0xA (10)]
BridgeOS Restore Error 10 – The Host and Target Mac need to be on the same OS Version.
Host Mac and Target Mac Disconnected during restore. – Error 4005
The OS Cannot be restored on this device.

BridgeOS Restore Error 0xFA5 (4005)
This error will come up when the restore process has been interrupted.
Or, you might get this using Apple Configurator 2 version 2.12.1, as the process never seems to complete properly. If the Target Mac awakes to the login window the process is complete even though the progress bar is at 100%. After unplugging the USB-C cable you will get the error above.
Apple Configurator 2 Reports RECOVERY instead of DFU Status.
Apple Configurator 2 Reports RECOVERY instead of DFU Status.
If you see RECOVERY this means that BridgeOS is unable to boot and is the default status when you power on the Mac.
Failed BridgeOS Restore due to OS Version Mismatch! The Target Mac is a previous OS i.e 10.14 trying to restore a 10.15 Mac, the update will fail with an Error 10
If the Mac already failed the Upgrade, it could already be in this status. If so, you can attempt a BridgeOS restore.
Configurator could not perform the requested action. Apple Controller devices do not support this action.
This means that you selected Actions > Update, which is not supported. You need to select Actions > Advanced > Revive Device
Apple Configurator 2 BridgeOS Firmware Download Location.
Thanks MrMacintosh Reader Max C for letting me know the location of the BridgeOS Firmware files.
UPDATE 01/02/21 – This article is only for Apple Silicon M1 Macs
Use a USB installer with Big Sur 11.2 to reinstall macOS
Enter macOS recovery. If you have FileVault 2 enabled, click the Recovery Assistant menu and then select “Erase Mac”. If you don’t have FileVault 2 Enabled or have already erased the drive, click utilities from the top menu bar and then click Terminal. Enter in the command resetpassword This will bring you back to the Recovery Assistant menu. Click the Recovery Assistant menu bar item at the top and then select “Erase Mac”.
UPDATE 11/19/20 – It looks like Apple has fixed the issue! I’ve just finished reinstalling macOS Big Sur from macOS Recovery and from a USB Installer drive. Everything works now!
UPDATE 11/18/20 –I originally reported that this error would happen on a factory build of Big Sur 11.0 (20A2411) but it also happens if you are running 11.0.1 (20B29). To review…
It doesn’t matter if you are using macOS Recovery or Big Sur USB Installer, you will be unable to reinstall Big Sur!!!
The only way to recover is by using a 2nd Mac with Apple Configurator 2!!
When the macOS is reinstalling the Mac will attempt to personalize the version that is being installed. You will get this error.
An error occurred preparing the update. failed to personalize the software update. Please try again.

How to Reinstall macOS on your Apple Silicon Mac. – Everything you need to know!!
Apple Silicon M1 Mac Recovery has changed! The interface, options and the way you reinstall macOS is all new. I will show you everything you need to know.
UPDATED 09/25/21
Apple Silicon Macs started to arrive in customers hands on Tuesday November 17th, 2020. One of the first things we need to understand is how to reinstall or factory erase macOS on Apple Silicon. All the old rules that you had to follow with Intel Macs has now changed. I will show you 3 different ways to reinstall macOS Big Sur on a Apple Silicon Mac.
If you are looking for more information on Apple Silicon Macs, I’ve wrote an article going over everything you need to know.
Right off the bat, we need to understand that Mac Internet Recovery on Apple Silicon is DEAD! Finally you don’t have to worry about IR errors and the problems that come with them.
Internet Recovery will still remain for Intel based Macs. For Apple Silicon we now have 4 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 Big Sur USB Installer Drive. = Boot to a createinstallmedia based Big Sur full installer.
4. macOS System Restore via DFU mode + Apple Configurator 2.

10. Signed? What does that mean?
1. Apple Silicon macOS Recovery
Apple Silicon macOS Recovery is almost exactly the same as it is on Intel Based Macs. One of the major things that has changed is the way that you get into macOS Recovery. Instead of having to remember a bunch of keyboard commands you can now use the power button to get right to the boot picker macOS recovery menu!

The video above shows you how to factory restore / erase your Apple Silicon Mac and reinstall macOS.
First line of defense, is macOS Recovery.
2. 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.
3. Both macOS Recovery and System Recovery are not available?
If something serious goes wrong with your Mac and it can’t boot into macOS you will see a new startup screen. (The blinking folder icon has been retired). You will now see a screen like this
Apple Silicon Startup problems – Prohibited sign – Credit Martin Nobel – https://twitter.com/martinnobel_/status/1321645315502432256
This screen has a new Apple Support URL support.apple.com/mac/restore which will tell you that you need to restore macOS firmware via Apple Configurator 2 and a 2nd mac running 10.15.6 or newer. Restoration will now work the same on the Mac as it does on iOS iPhones and iPads.
4. 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!
Now you can build out an USB Installer of macOS Big Sur and boot your Apple Silicon Mac to it.

Mr. Macintosh Video on how to use a USB Installer to reinstall macOS on Apple Silicon!You can now boot a USB macOS installer without enabling external boot in Security options! It’s enabled by default.
5. 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 = Will restore macOS Recovery Only. (User data remains)
2. Restore = Will will download macOS and macOS recovery and reinstall them (THIS WILL ALSO ERASE YOUR HARD DRIVE)
This will help with rapid deployment in lab / school situations.
My Mac T2 BridgeOS Restore article will show you this process. It has not changed except for one thing. In the future the “RESTORE” option will automatically download the newest macOS ISPW file for you and install it. For now you will need to download it and and drag it over to the DFU icon.

I’ve also written an article that goes over the entire new DFU + Apple Configurator 2 Apple Silicon Restore process below.
1.Full Security = “iOS Security” – Only the latest signed version of macOS can be installed on an Apple Silicon Mac.
Full Security
Ensures that only your current OS, or signed operating system software currently trusted by Apple, can run. This mode requires a network connection at software installation time.
WWDC 2020
2. Reduced Security = Any version of macOS that was signed by Apple.
Reduced Security
Allows any version of signed operating system software ever trusted by Apple to run.
WWDC 2020
With the new Apple Silicon Security Policy, you can set a security policy for each container! On an Intel based Mac the security policy would be set on the entire system.
New Apple Silicon Security Policy can be set differently on each container.
7. 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
8. Can I downgrade macOS on Apple Silicon?
Yes!
Note. The “Shipping version” of macOS on Apple Silicon is the lowest OS that can be installed. An example of this is the M1 iMac which came with 11.3. You can not install Big Sur 11.2 on it.
9. Where can I get macOS ISPW Firmware files?
I started a new database page that will keep track of all macOS Apple Silicone IPSW Firmware files.
Starting with Apple Silicon, macOS OTA (Over The Air) Firmware will be signed by Apple. This means that they control which version of macOS can be installed on your Mac. The difference this time around is that Apple gives us the option to turn Signed Checking OFF. So you will still be able to install older versions of macOS.

macOS Big Sur 11.0.1 – Installation failed An error occurred while installing the selected updates.
macOS Big Sur was launched at 12:00PM CST. A few hours later, users started to report download problems.
UPDATE 02/20/21 – I’m still getting a bunch of people reaching out saying that they are still getting the error even after Apple fixed the issue! You can download the full macOS Big Sur installer directly from Apple’s servers via Safari.
What this will do is download the entire InstallAssistant.pkg file. Install this package and it will put macOS Big Sur into your /Applications folder!
UPDATE 11/12 7:30PM CST – The download is working in the Software Update pane now. LET THE BIG SUR DOWNLOADING COMMENCE!!!
UPDATE 11/12 7:00PM CST – Some users are reporting that the download is starting to work. installinstallmacos.py is working for me but I’m still getting the error in the Software Update pane.
If you were able to download the full Big Sur installer before this issue happened, then you are one of the only people with a full installer right now! Maybe you can burn it to a Dual Layer DVD and sell it on ebay haha! (will have to be a blu-ray disc as a DL dvd is only 8.5GB and the Big Sur Installer is 12.2GB LOL)
This is the error you will get on Big Sur when trying to download macOS Big Sur.
My videos explaining the issue is below.

Apple Server issues.
Apple did report a server side issue for macOS Software Updates.
That section was marked as resolved though at 3:30 CST. The problem is, the download is still not working.
The issue is with one file
After digging in, the issue is with one file installassistant.pkg
If you use installinstallmacos.py to attempt to download macOS Big Sur 11.0.1 (20B29)
curl: (22) The requested URL returned error: 403 Forbidden
Could not replicate http://swcdn.apple.com/content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg: Command '[u'/usr/bin/curl', u'-fL', u'--create-dirs', u'-o', u'./content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg', u'--compressed', 'http://swcdn.apple.com/content/downloads/50/49/001-79699-A_93OMDU5KFG/dkjnjkq9eax1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg']' returned non-zero exit status 22
We do not have access to download InstallAssistant.pkg and get a 403 Forbidden Error.
Once this issue is fixed, I will will let everyone know.
Once access to this file is restored, we should be able to download Big Sur again. I will keep you updated.
Release Candidate (20B28) and the 11.0.1 Final (20B29) Release Notes are the same.

Full-height sidebars
A new look for app sidebars makes it easier to find what you want and gives you more space to get things done. Easily track your Mail inbox, access Finder folders, and organize Photos, Notes, Stocks, and more.
New symbols throughout macOS
New symbols in toolbars, sidebars, and controls bring clarity and consistency across apps, helping you immediately recognize where to click. When apps share common tasks — like viewing the inbox in Mail or Calendar — they share the same symbol.

The error message that you will get if you try to upgrade a T2 Catalina or Big Sur Mac to 11.0.1 RC2

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.
