Upgrade Mavericks to Big Sur
I have a mid 2014 Macbook Pro, checked and it is compatible with Big Sur. It is currently still on mavericks.
When trying to update and download Big Sur from the app store i get the error:
"downloading the installer build manifest failed."
What should I do? Downloading from the menu bar -> software update doesn't work either.
I can't run any apps because of this.
