Thanks for your guys working together to fix the slow down and lag. Great fix!
Thanks guys for the AppleHDADisabler. My system is stable now after installing it in my clover EFI folder (crossing fingers).
I currently have 10.4.6 running with the i9 7980XE, ASUS WS X299 Sage motherboard, & ThunderboltEX 3 adapter. I would constantly get random kernel panics after installing a newly bought ASRock Radeon VII - KP time would vary from 20 minutes to 2 hours from boot time.
I wasn't getting the KP with a dual 1080ti setup before - had to switch obviously since latest Nvidia cards aren't supported. Although the onboard sound is disabled on my system, I'm using my OWC thunderbolt 3 hub to get audio. It shows as OWC Thunderbolt 3 Audio Device on my system preferences.
So far so good. No slowdowns or KPs. Premiere Pro and Davinci Resolve are running smooth using Metal.
Now that I had gotten the card to play nice in Mac OS, I finally flipped over to Windows to check out gaming performance. Unfortunately, I'm plagued with the "black screen" crash where randomly, screen goes black and audio stays for a bit, then system locks forcing hard reset. Googling shows this has been happening since March and for many people, and on the latest Adrenalin + Win 10 it's still doing it. #womp
Between such slow updating, poor performance and support in Windows as well as broken native support in Mac OS coupled with AMD dropping production of these cards...I think I'm abandoning ship, at least for now. I can't even game on the card in Windows unfortunately. I can't wait in hopes it'll come around as the card loses value by the day. : /
I'll keep my eyes here as time goes on and maybe I'll come back to one down the road! Happy to have helped sort a temporary fix, at least. Best of luck!
Thanks guys, honestly all this was enough to give me cold feet; not trying to have this much hassle with a $700 piece of kit. I'm going to wait out further support from Apple and AMD and see what happens. I was lucky to get AMD to agree to a return with the kernel panic evidence from both Mac OS and Windows combined. Seems normally they don't take returns on opened items. I'm going to take the opportunity to get my money back sans shipping and stick with the Vega for a bit longer.
Thanks again guys!
