unable to update to Mac OS Big Sur, Why?

1. Go to the Applications folder (Finder > Go > Applications), find the macOS Big Sur Installer app.
2. Drag it to the trash and empty the trash.
3. Restart the Mac
4. Use this link to get Big Sur: https://apps.apple.com/us/app/macos-big-sur/id1526878132?mt=12
5. Download and install macOS Big Sur.

Also, make sure you have a backup before updating to Big Sur!!!

Hi there,

Your Mac may not support macOS Big Sur. Go to the Apple Menu (top left) > About This Mac, and post the Mac year.

Cheers,
