Black Screen After 10.10.3 update

[weswes]

This what you have to done first, but you updated on post#71 that you have done it.

No, on post#71 that kext did not work. I found the kext I used to fix the issue in post #79, here:

OS X 10.10.3 Update post #212

hi guys! My English is bad, but I will try to help you.
You need to connect in your host and to make modification of the Info.plist file which is on the way


/System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/


In this file you look for Mac-F60DEB81FF30ACF6 = Config1 line and you replace it with Mac-F60DEB81FF30ACF6 = none

Save.


You do update cache, for example by Kext Utility.
Reboot

Please help! After modifying this I can only get access into Yosemite via Safe Mode, but once I reboot in normally I still got nothing but black screen. I cleared cache using kext utility, graphic card Radeon hd 7850m, I successfully boot into 10.10.2 using dsdt file. Can anyone please help~~~~

I made a dummy kext that will load the modified info.plist even after future OS updates. Just install with KextBeast or your app of choice.

Shows the OEM kext not loaded because the dummy kext has a newer version and overrides it.



Shows the dummy kext with the modified plist loaded. There are symbolic links so the kext will load the binary and other files from the OEM kext.


Credit to PikerAlpha for his new way of patching AppleHDA method. kext doesn't work right. Clover's plist patch won't do it either. Still have to patch the plist.

Update your build's hardware details under Profile > Basic Information section in the below format (Profile link is available on the upper right side of this website). Without hardware details no one can help you.

For Example,

Still having issues with my system. I've got my GTX 770 hooked up to two 27" Monitors; one via displayport (not working) and the other via DVI (working fine). This was all working in 10.10.2 btw.
I tried both Kexts provided here then I noticed that my board-id (14,2) was not present in the Info.plist file. I manually added it and set string to none.
Still no luck; I even tried setting string to Config1 to see if that made a difference. Any ideas?
