I’m trying to update my MacBook Pro 13 from Catalina to Big Sur..... I am unable to update as it says “an error occurred applying the software update”. I had taken a time machine backup... it doesn’t show up right now! Is there anything I can do? It’s urgent.... I am a student and need to be attending class using my laptop
Hey I had the same problem but I have a solution. What you do is you restart your mac on the screen where is says an error occurred while applying the update and as your computer starts hold down command and "r". Then it will start macos recovery. There you choose your user and type in the password and then choole install mac os big sur. It will download a fresh copy of the update and install it. It worked for me hope it helps.
Hey everyone,
I had that problem while updating for the BigSur and my computer got stück. During the initialization, the computer
was entering automatically in recovery mode (or something like this) and saying that there was a problem during the
installation of the new OSX.
I then entered in recovery mode before the installation try using (cmd + shift + r) and managed to reset the mac to factory configurations, which means back to Maverick OS and just then entering there the Apple Store and re-downloading and re-installing the BigSur. Finally, I used the Time Machine I had in an external drive to retrieve my documents and stuff.
I hope it helps someone out there that got into this inconvenient trouble.
Here's the fix: External. Plug in your MBP/MBA SSD via External Adapter, and install Big Sur from a USB Bootable.
I had a client with a Early 2015 MBA and her issue was the same. She went to the apple store prior, and they installed a new SSD temporarily and got Big Sur to work, so they told her she needed a new SSD, because the Genius Bar wasn't able to get Big Sur to work on her current 500GB SSD, only Catalina. I ran into the same issues no matter what I tried. The issue is the internal SSD becomes Unmounted during the installation process, most likely from the installer package, and doesn't Remount.
The solution that worked for me was to plug her SSD into an external adapter, and then load Big Sur that way. I also tried a 2012 MBA SSD via External Adapter on her 2015 MBA and Big Sur installed perfect as well.
Seems like when it's plugged in externally it's not having that dismount problem.
Same issue. Even after “Command + R” into macOS recovery, there is no volume to recovery. Donno what to do now.
same problem and now stuck on recovery page with all the option but unable to select anything as screen stuck. Any suggestions?
I think there is no solution for this issue. I called Apple support but they couldn't help me. Unfortunately, I did formatting and I lost everything 💔
Thanks to Big Sur 💔💔💔💔
mouse not working now curser stuck can’t choose anything
This line doesn’t go away after the new update
If you went into Recovery disk, connected to the internet, didn't you have access to the Disk Utility?
What computer and was it operating properly before you tried to upgrade to OS 11?
Do you have time machine backup before upgrade?
Finally I need apple support to reset my Macbook Air and I restore my files from time machine backup.
Yes I have a TM backup, how can I use it considering that I cannot access the system in any way.
the same to u...
What do u mean command r? I hold down command r and nothing happened
an error occurred applying the software update
