Black screen here too using Mac Pro 6,1. Going to roll back for now.
The update of my Clover GA P55-USB3 with HD6670 went fine, but this made me a bit worried, do you mean i need the original 10.10.0 AppleHDA.kext backed up? What if I started on 10.10.1 and only have that one backed up? Maybe I should try to dig up an old USB with Yosemite 10.10.0 if I still have it and keep it in storage.
Just tried the following for TRIM and worked:
sudo perl -pi -e 's|\x00\x41\x50\x50\x4c\x45\x20\x53\x53\x44\x00|\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00|' /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage sudo touch /System/Library/Extensions
How do you boot with nv_disable=1? Can you walk me through this?
Just write nv_disable=1 in the boot menu (assuming you have an nvdia card of course)
and when you go to desktop just reinstall what you need from multibeast (audio,trim) and change system definition
it worked for me ...so you can try it
try it maybe in safe mode...Having the same problem as well, I'm able to boot with nv_disable=1 but changing the system definition doesn't help at all! I've tried 15.1, 5.1 as well as 14.2 but none of them works. Any idea how to fix it?
