You have to change the CFBundleIdentifier like this

 

<key>CFBundleIdentifier</key>

 

            <string>com.apple.kext.AMDRadeonX4000</string>

Same thing happened last year with Sierra DP1. Was fixed in DP2 by the system itself, not a new version of Verde.kext. So I guess we just need to wait next release…

 

In the meantime, editing the AMDRadeonX4000.kext as per post #1 should do the trick but it's important to NOT use Verde.kext as well.

I have an system without integrated GPU (in the cpu). I use Quad Q9550, is an cpu only.

Will it work without that? Or must i have integrated gpu for using that fakeSMC_verde version to get AMD 7xxx working?

It will work, but this patch is only for the black screen after boot up, and not after wake up and it only works for AMD verde cards. An IGPU is only needed to wake up properly.

THANKS!

I didnt know the sleep/wakeup problem. So that problem is for me to much - without sleep/wake i stay by nvidia. Until sometimes i buy new boud/cpu with IGPU :)
