[Solved] Only boot from unibeast with nv_disable=1 -x -v after 10.10.3 update
Hi there... Since last time I had A LOT of trouble after the 10.10.2 update I said to myself I would not update again....and then apple comes with 10.10.3 and the release of new application Photos... I could not resist.
I updated from a stable installation of 10.10.2, to 10.10.3 using the App Store. The install went ok but after I could not boot, at all. My system would hang for hours on the apple logo and the loading bar at 50%, booting with -x did not help and -x -v would only lead to a blackscreen +reboot
The only way I could boot was on a unibeast key (made with 10.10.3) with the flags -x -v nv_disable=1
So I thought it was a driver issue even though my 770 was running perfectly in Yosemite before, and I decided to install nvidia webdrivers. Still does not do the trick.
So it's been 2weeks now my computer is unusable and I don't know what to do, I feel desperate because I tried EVERY things
I uninstalled webdrivers, updated to the new 10.10.3 extra update, same problem, installed new nvvidia drivers, but same problem, so I desinstalled them. So I'm still stuck, can only boot with -v -x nv_disable=1 and only from the unibeast key. It's very slow and there is no sound so it's not really usefull.
if some one could help me that would be awesome.
also what is the difference between nv_disable and nvda_drv flag ? (My nvda_drv is set to 0 now).
cheers
PS :
When booting with -v, or -v nv_disable=1 it will stop and hang here :
and if I boot with just -v -x, it will go through this but my monitor goes off (no DVI signal)
the only way to boot is with the combination of -v -x nv_disable=1 , and only from the unibeast usb stick, if I try that from the SSD bootloader it will get strait black screen after a few lines drops.
My boot.plist has nothing special but nvda_drv=0 (that i put recently because I wanted to be sure it does not load the webdrivers) and IGPEnabler=No GraphicsEnabler=No (only using the GTX 770, Integrated graphics is deactivated in the bios) that's how it was before and it was running perfectly.
I did not try to plg my screen on the motherboard ad re-activate internal graphics, I'm pretty sure it might work but it's not a solution, I need my GTX.
