MacBook Pro frozen even after reboot
I have a MacBook Pro with Retina that is about 3 years old. About a week ago, I was on the computer one night and closed the computer and went to bed. The next day when I went to get on the computer, I opened it up and it let me type in my password but then the computer was completely frozen. I could not type anything or move my mouse. I held down the power button to force it to shut down, waited a few seconds then turned it back on. When I turned it back on, it was still completely frozen, I couldn’t type in my password or move my mouse. I turned it off and back on several times and nothing worked. I finally turned it off and left it off for about an hour. After about an hour, i turned it back on and it worked fine. In the past week, it has done this several times. The only thing I can think that each time has in common is when it happens, safari is open. It does not do it every time I close it and don’t exit out of safari though. It does seem that I have to leave it off longer each time it freezes.
