Trying to help my son who lives away from home and has a MacBook Pro with Yosemite. Suddenly started asking for an update on startup saying "The user graphics resource appears to be invalid" and asks for password. Accepts password then goes to a white screen and nothing happens.
Unable to boot into safe mode, verbose mode, or recovery mode. He doesn't have another drive to boot from right now.
Any other ideas to get it started?
