OSX 10.10.3 Update // video turns off after apple logo appears on startup [BLACK SCREEN]

[Manofstyl3]

Hey guys,

I am using CLOVER. Has been running smooth for months until I updated to OSX 10.10.3 yesterday. After a fresh restart, the video driver/card (I'm not sure the issue, but I suspect a few simple key commands would correct this?) simply shuts off as the apple logo finishes loading (video clip HERE). I know that everything else is functioning properly because after a few min of the black screen my Pandora radio starts playing (so the desktop loads, just loosing some connection with the screen at some point in the start-up/load process).

NOTE: I know the screen is ok because the machine starts just fine in "safe mode". I've also swapped out 3 diff video cards to confirm the card is not the issue. Same issue with all 3 cards. I'm certain it is a software/driver issue...

I know this is probably a very easy fix, I am just not very knowledgeable of what "key commands" or prompts to use to get the video card driver functioning as it should. My tech-guy who usually fixes issues like these I remember him doing some quick "key commands" and BOOM! We were good to go however, he is currently un-reachable so I'm trying to get this rolling by myself.

Once again, here's the 10 sec video clip of what I am getting... HERE

THANK YOU kindly for any support you can provide.

Boot into your system using the safe mode.

At the desktop, run the terminal app with this command " sudo diskutil repairPermissions / "
which will repair permissions. Then reboot normally.

Depending upon how your Clover is configured, you may need to re-install your audio fix.

or

You can restore you system with your backup.


Good modding,
neil
