Why won't my MacBook Pro start up from the grey prohibitory sign?
My MacBook Pro won't turn on from the grey screen. I have tried refreshing the RAM, and that has not worked. I tried placing the start up disk into the computer when turning it on and that still has done nothing.
It takes a while for it to get to the prohibitory sign. Before the prohibitory sign it usually has an apple and it just sits there for a while.
I don't know what to do.
Help is wanted.
Thank you very much!
