Boot loading bar gets halfway and hangs
My computer has been in a closet for over a year and I tried to start it to clean it up for my grandchild.
When I turn it on, I hear a “gong” then the Apple logo appears and once the loading bar gets halfway, it just hangs and gets stuck. It was just staying illuminated like that.
I tried to start it in a safe mode by pressing SHIFT and restarting. The result was similar but now it goes dark after it gets about 1/3 of boot.
Thanks in advance!
