How do I back up my MacBook Air (13-inch, Mid 2011)
I have a MacBook Air (13-inch, Mid 2011) that still works quite well. But I want to back it up and can't find a CLEAR, non-contradictory description/advice for exactly what I need. I don't want to lose anything.
THANK YOU from a totally computer-challenged user!
MacBook Air 13″, macOS 10.13
