MacOS – Cannot update from Catalina to Big Sur on compatible Mac: “The requested version of macOS is not available”

big surcatalinamacossoftware-update

I want to update from macOS Catalina to macOS Big Sur on a supported MacBook Pro (Retina, 13-inch, Mid 2014).

Yet System Preferences > Software Update shows “Your Mac is up to Date – macOS Catalina 10.15.7”.

The App Store says macOS Big Sur “Works on this MacBook Pro”.

When I click the “GET” button, System Preferences > Software Update opens and says: “Update not found. The requested version of macOS is not available.”

macOS Big Sur Update not found

I found here a similar question regarding updating to a prior version of macOS but could not apply any of the answers successfully.

What can I do to update to macOS Big Sur?

UPDATE:
macOS 11.1 was just released, and now I am offered to update!

Best Answer

The option to update to Big Sur came back with the release of 11.1.

In the comments an article was mentioned that reported that 11.0.1 might have been intentionally blocked for certain MacBook Pro models because it caused lasting damage (Thank you @Tetsujin & @bmike):

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.
