The first time:

I have not shut down the computer in about 2 weeks, always on sleep at night. Before I turned it to sleep, I used ScreenFlow and perhaps also checked my email. I just moved the computer from room to room and waited about 30 minutes before turning it on. I saw the log in screen for 1 second, and then it went to the gray screen.

Here is the problem description:

I didn't care about it that much since it's been a few months since I had my last gray screen. However, about 2 weeks later, I had another gray screen. This time I started playing a youtube video, and about 2 seconds in, I unplugged my headphones to hear it on the speakers. Before I heard anything, the gray screen appeared.

They both contain the same Kernel Extensions in backtrace of come.apple.iokit.IOAudioFamily and com.apple.kext.OSvKernDSPLib. Does anyone know what caused these problems and possibly how I can fix them?

  • Did you reset your SMC? – Ruskes Sep 12 '14 at 20:18
  • Hi buscar웃, I have not reset my SMC, should I? What do you think caused the problem? Will resetting the SMC do any damage or erase any data? – Alice Sep 15 '14 at 1:46
  • Nope, resenting the SMC will not do any damage, since it shows IOAudio, SMC might do that. – Ruskes Sep 15 '14 at 4:24
