Anyone having color flashing issues with 10.12.4?
AMD Radeon HD6790 with modified Info.plist on AMDX3000 and AMD6000Controller, was working perfectly with 10.12.3.

yes, my hd5750 is color flashing on 12.4. It was flashing during all the betas too. Had heard of others during betas that had radeon flashing, but no solutions or comments

@LostVector So i regrettably updated to 10.12.4 and now my MST doesnt seem to be working... Everything was working with my RX480 and dell 5k prior to updating, not sure what exactly about the update broke my MST support. Would you mind sharing your AGDP plist with me?

Updating OS versions overwrites the kext ... did you try just making the edits again?

Yeah, i even restored the previous version of the kext via time machine but i couldn't get it working again so I was thinking maybe I hadn't done something correctly in the first place and just got lucky with it prior to update. You just need to remove all the board-id's from the the AGDP and that should allow it to work right?

I would remove just the board-id of your current SMBIOS. I haven't updated yet.

Also make sure to force your kext cache to rebuild and that unsigned kexts are enabled.

"sudo touch /System/Library/Extensions && sudo kextcache -u /"

@LostVector Really appreciate your help. I tried those suggestions however I can't seem to get the RX480 and the 5k to work again like it was in 10.12.3. The terminal command was useful to know since I hadn't been doing that prior. I also made sure to enable dev-mode in my clover boot args which it wasn't. I eventually nuked all the board-ids from the config plist because after I couldn't get it working the first time (with only the relevant board-id removed) I kept switching around different Mac Definitions to test. (For Reference when it was working correctly on 10.12.3 I was using iMac17,1).

For now i'm using my nvidia 980ti because 5k is still working on that (back to having that cursed cursor glitch), just super frustrated I updated when everything was working so well :banghead:

I uploaded my Clover config plist, AGDP info plist, and a screenshot of the terminal command results if you have a chance to look at it or maybe could let me know if something looks incorrect to you. Anyway thanks again for all your help.

OK, I updated and lost 5K.

Turns out I may have missed something in my initial post. Make sure CFG_USE_AGDC is set to true in the plist for whatever accelerator.kext is used for your card. Probably in the default section, but if you are using a custom framebuffer then you might have to override it in the configuration section for that framebuffer. Still testing but that's when I got 5K back ...

aHa!!!! Totally working again! You were exactly right! That was the key to get it up and running again. And honestly I don't know how you figured that out because I would have never been able to find that out on my own in a million years. :clap::clap::clap:
