My 15” MacBook pro has an annoying issue; it will either stop suddenly and will not restart, or when I try to boot up after previously running, OK will not restart. In both instances, there is a black screen, and the fan is running.
I can stop the fan running with the on/off button. If left untouched for a while, the computer will boot up all OK as though nothing had happened. The MacBook is not overheating as I have an external fan.
What can be causing this?
