Startup disk full, computer won't turn on!
Hello!
Recently, every time I turn on my MacBook Air, after the startup chime, a window pops up saying the startup disk is full. After that, the screen stays blue with just my mouse on it. I just tried turning it on again before writing this, and the window doesn't even show up anymore! Please help, I have very important data in it and I never backed it up 😟
Thanks!
MacBook Air
