Updated to 10.8.3, and now have black screen

[theshiv]

Hi all,

I just downloaded the "10.8.3 Combo Update," installed, ran MultiBeast for audio and trim, and then restarted. Right after the boot loader kicks in, my screen goes black. I can boot fine using the UniBeast USB stick, but I can't figure out what's causing this problem.

I've gone through my .plist and all looks well. Any thoughts???!?!?!?!?!?!?

Thanks!

Any chance this is causing something?

In the Extra folder I have a filed called: nvram.5002e503-4904-3905-1006-590700080009.plist

I've never noticed it before.

this also happened to me before, during my installation i couldn't get to boot screen it just black.
have you try to boot without ur GPU?

I can't use the internal GPU on my CPU, so no. However, I used this method and it solved my problem: http://www.tonymacx86.com/os-x-updates/92678-10-8-3-can-no-longer-boot.html

I had the same problem followed the instruction as posted works like a trait

I thought i had the same problem, spent two days but the above fix didnt work for me.

After updating to 10.8.3 my machine booted normally but at one stage the screen turmed black. I could send the machine to sleep, wake it up, still no screen.

Finaly solution: unpligging DVI cable and repligging it.

Since then: perfect!!!
