Now, let's check them one by one and dig for a solution.
1. Data issues in macOS 11 update
In latest 10.15 Catalina and macOS 11, Apple splits the startup disk into two separate volumes, System and Data. It makes data backup difficult especially those apps making (and restoring) bootable backups.
Therefore, it's always recommended to back Mac files up before every major macOS update using the built-in Time Machine.
If you upgraded to macOS Big Sur on a Mac that uses a Time Capsule or other network storage device as the backup destination, your existing backups are also upgraded and can be used only on macOS Big Sur. New backups that are created can be used only on macOS Big Sur.
If you are using a third-party software to back up, then you need to wait until it's ready for macOS 11.
How to restore or recover lost files after macOS Big Sur update?
Though Apple has made a precaution that important files might get lost if the macOS update is interrupted, many of us still forget to back up our Mac with the built-in tool Time machine. As a result, private data like photos and documents might have gone once after updating the system.
How to fix:
- If you have backed up your Mac to an external hard drive with Time Machine, you can simply restore the Time Machine backups.
- How to restore Mac files from Time Machine backup?
- If you don't have any backup while the failed macOS Big Sur stops your Mac from booting up, you can try iBoysoft Data Recovery for Mac to get files off Mac that won't turn on.

2. Fail to download and install macOS Big Sur
macOS 11 fails to download with some messages like 'The network connection was lost', 'Installation failed', or 'there is not enough space'.
Can't download macOS Big Sur or take a too long time, what to do?
With a large size of over 12 GB, it might take a while to download macOS 11. However, if downloading the software takes time more than you expect (like hours), some things go wrong. In some cases, messages like 'macOS Big Sur download has failed' might cast a chill over you.
How to fix:
- Check your Internet connection (either an Ethernet or WiFi) and make sure it's fast and stable enough.
- Make sure the task of downloading macOS software update is working fine. Or you can restart your Mac and try it again.
- Make sure you have made enough room for the software on the target disk.
Can't install macOS Big Sur on Mac, why?
A successful macOS software update is not as easy as you think. After downloading, if macOS Big Sur won't install on your Mac machine, all your effort might be in vain. Your Mac may freeze on setting up your Mac, and some older MacBook Pro machines even get bricked by macOS Big Sur.
This could be a result of installing into the same APFS container as previous versions of macOS Catalina 10.15. Another possible reason for 'macOS Big Sur Cannot Be Installed On This Computer' is that macOS 11 simply is not compatible with your Mac (e.g. iMac 2020, Retina 5K, 27-inch).
How to fix:
- If you can't upgrade from macOS 10.15 Catalina to Big Sur, you need first update to 10.15.6 before installing macOS Big Sur.
- If your Mac is T2-secured, to install macOS Big Sur, you need to boot your Mac to macOS Recovery mode > Utilities > Startup Security Utility, and then make sure the Secure Boot option is NOT set to 'No Security'.
- If you receive the error 'you may not install to this volume because it is currently being encrypted' when selecting a disk to install macOS Big Sur, wait for the disk encryption to finish and then disable File Vault in Safe Mode (Apple menu > System Preferences > Security & Privacy > FileVault) before reinstalling.
- If you fail to upgrade to macOS 11 Big Sur and receive 'an error occurred applying the software update', try to restart with 'Command + R' or 'Command + Option + R', and then reinstall macOS in macOS Recovery Mode.
- If you fail to install the macOS software because the Mac goes sleep while preparing macOS Big Sur 11, you can simply adjust Energy Saver settings by Apple menu > System Preferences > Energy Saver and then try it again.
macOS Big Sur bricked some incomaptible Mac models
Another possible reason for 'macOS Big Sur Cannot Be Installed On This Computer' is that macOS 11 simply is not compatible with your Mac (e.g. iMac 2020, Retina 5K, 27-inch).
Make sure your Mac is in the list of compatible models. DO NOT install macOS Big Sur if you are using a MacBook Pro earlier than late 2013 and mid 2014. If it has already casued a problem, you need to reinstall macOS or downgrade the macOS to Catalina.
3. Startup issues after installing macOS Big Sur
After installing macOS Big Sur, the Mac will then automatically restart from the newly installed system. What comes along with is a repeated boot loop, restarting, black screen, and then loading macOS 11 Big Sur. But if any problems occur or any part of those gets stuck, the Mac fails to turn on.
You might see it stuck on the loading screen with an Apple logo, or return some symbols that you have never seen on your Mac, such as a flashing globe, a folder with question mark, pink screen of death, or a prohibitory icon. Finally, the macOS update just crashed and bricked your computer.
How to fix:
- Force your Mac to restart.
- Repair your Macintosh HD by booting into macOS Recovery mode > Disk Utility > First Aid.
- Restart your Mac to Safe Mode and reinstall macOS
- Erase your Macintosh HD and create an external bootable installer.

External hard drve is read-only in macOS Big Sur
This is a long standing issue in macOS, not only in macOS Big Sur. That external hard drive is read only after plugging in to the Mac machine, which generally is caused by the Windows NTFS file system. So, if you can't write to your disks, check those things:
- Change device share permission by right clicking > Get Info > Sharing & Permissions

Can't use Airdrop in macOS Big Sur, how to fix?
What Is Mac Os Catalina
You might be unable to use Airdrop for files transferring and sharing in macOS 11. This could result from System Integrity Protection (SIP), which is a bug for macOS Big Sur beta. You can simply go to disable SIP.
There are many other software issues like software unexpectedly quit, and apps like VirtualBox, AdGuard, Chrome, and Steam won't response in macOS Big Sur. What we can advise is to downgrade to a previous system like macOS Catalina and Mojave, and do not upgrade to macOS Big Sur until it is released to the public in a stable condition.
Verdict
No one can guarantee that updating to macOS Big Sur is 100% safe, especially in the buggy stage that bursts out problems like:
- Data loss and macOS 11 update failure
- Startup issues after installing macOS Big Sur
- Poor performance when using macOS Big Sur
- Built-in or third-party apps issues
But what you can do is to back up your Mac files and get noticed possible problems. Then, when you want to upgrade to macOS Big Sur, you won't risk data loss and you are prepared for known issues and data recovery.
