I have a 2nd hand macbook from around 2015.
When starting up I get:
"A critical software update is required for your Mac, but an error was encountered while installing this update.
Your Mac can't be used until this update is installed."
I clicked Try Again several times, but it ends up the same way every time.
What to do?
BTW I'm new at Mac and only have some experience with Linux.
