SAYS to select disk on my 2012 Mac Air but I can't find a disk. Where might that disk be?
I want to give my old 2012 Mac Air to my grandson but it seems to have lost its ability to sign in. I have gone through the steps to where it says "Elect the system you want to use to start up your computer>" What do I type I the blank box? Doesn't show anything to select. And comes back and tells me basically there is not start up disk chosen (because there is none shown) So I hit [RESTART} and I'm left hanging? SO where do I find a start up disk if none is being shown?
MacBook Air 11″, macOS 12.1
