I restarted my macbook pro this morning and it started up with a chime and now is stuck on the grey screen. I have tries holding any different key combinations, none of them work, except resetting the pram, which does cause the computer to restart.

I have tried option, r, s, d, command shift v, command v, shift (before and after the chime), command option d r.

FYI I have been running yosemitr for a while with no problems. I shut my computer last night and it was working fine. This happened when I turned it on today.

  • Can you provide some more details? Year purchased your computer, specs, etc? Have you just installed Yosemite and this is the first time booting, or have you been running OS X 10.10 for a while now? How long was your laptop on since you last restarted - I ask because Apple just released the 10.10.1 update and I wonder if it's failing to complete that update...

  • OK added some context details. I'm unsure if it got the latest update, but I think so like a weak ago. Nov 25, 2014 at 4:22

Disconnect everything from the Mac and then power it off.

Perform recovery according to these steps.

If that fails, then you may need support from Apple to determine the version of OS X that shipped with the Mac so you can restore that and start over/restore from a backup once the hardware is known to work. Or it needs a repair for hardware issues.

  • I am gonna bring it to an apple store tomorrow. Command r has no effect when starting up. Nov 25, 2014 at 4:23
  • @saul.shanabrook Good plan - when the system can't even boot to internet recovery, something hardware is usually involved.

I press ⌘cmd+⌥alt+⇧shift+⎋esc, and then the login screen appears. It's always after an update that this happens. It has usually righted itself eventually.
