Hi, I have an iMac 2013 and I just upgraded from Maverick to Yosmite directly , apparently without errors. But every time I reboot, the music plays and get a black screen with the apple and progress bar and finally loads the Yosmite , is it normal? In Maverick came out apple logo on the blank screen and quicklyboot
Sorry for my bad English and thanks
iMac, OS X Yosemite (10.10)
Hi, thanks for the response and I read the links. I was running tests:
- Verifying permissions and disk ... and nothing.
- Yosemite Restore cleaned and maintained the same restart
- I even went back to OSX Lion and the restart was a clear display and gear.
- From Lion upgrade to Yosemite, and came back the restart with the dark screen and progress bar
Therefore, the restart of or Yosemite is right (like the Iphone) or there is an error with the installer Yosemite because I discard hardware problems ...
Black screen on reboot with Yosmite
