Failed to update MacOS from Catalina

My Device is a MacBook Pro 16 in 2019 intel

I am currently running 10.15.7 I am trying to update the software. But I am just getting the spinning wheel. When I try to download Big Sur through the app store nothing happens.


Any suggestions besides wiping the device?

Good advice from John Galt, if that doesn't work...


Start up from macOS Recovery

Option-⌘-R

Upgrade to the latest macOS compatible with your Mac.


In Disk Utility>View, select Show all Devices, highlight the top left entry.


APFS won't work for Sierra or earlier, Sierra or earlier needs MacOS Extended Journaled. High Sierra won't work for APFS on earlier Macs.


What has often worked for others is to use this Restore Method instead of CMD+r keys...


Option-⌘-R

Upgrade to the latest macOS compatible with your Mac.
