Yellow plain screen on login, 10.12.4

[funkyfrank]

Hi,

I upgraded my OSX to 10.12.4. Using an ATI HD 7750 deviceid 683F, which worked ootb in OSX 10.9.4. When the graphics driver kicks in - in verbose mode - I only get a plain yellow screen... If I enable "InjectATI", it will lead into a disabled screen (did not use that option in OSX 10.9.4).

I have no idea how to fix this...

Is there a similar option like "nv_disable=1" for ati gfx? EDIT: Ok, safemode does this job and it works, but without acceleration. Hm. Any idea please?

Thanks for help!

Try using Verde.kext [SUCCESS] Gigabyte GA-Z77M-D3H Rev 1.0 + HD7750 + 3 Monitors

I had a green screen when upgraded to 10.11.3 and solved by using Verde.kext. And today I had the same yellow screen problem when I upgraded to 10.12.4 at launch time, but I'll try to fix this at night.

Hi,

Put this file into EFI/CLOVER/kexts/Other (create dir if not exist).
Sleep mode will not work (card does not wakeup), I don't know a fix for that.
