Every time I reboot from Boot Camp into OS X, the bootloader gets to the login screen, and then after I've entered my username and password, the screen will just go grey. I have to force a restart with the power button, and then when I reboot, it proceeds normally.

Specifics: Windows 7 Professional 32-bit in Boot Camp, and OS X 10.7.1. The same issue happened with 10.7.0. This is on a late-2008 MacBook Pro 15".

  • do you have Sophos Antivirus installed? – Stu Wilson Mar 21 '12 at 20:53
  • Is this still and issue? If so, what version of OS X are you running now? – Nate Bird Mar 23 '12 at 18:07
  • Not happened for some time now, don't know what actually fixed it. I'm now on 10.7.3, and yes i do have sophos installed – MrBliz Mar 24 '12 at 15:59
  • Try updating to Lion 10.7.5 – PoisonNinja Mar 11 '14 at 1:46

This suggestion seems to helps a lot with all sorts of things, so I figured I'd suggest it here just in case.

Go to your Disk Utility app and press the following buttons in the numbered order. I would recommend only doing 1, 2, and 3, but if this doesn't help with the problem, you can also try to run 1(b) from Recovery Mode (or while running your computer off an external hard drive) because it won't work while you're logged on.

Hope this helps :)
