    Can anyone recommend a Graphics card that works out of the box on Catalina?

    My PowerColor RX 5700 XT Red Devil has worked out of the box with iMac15,1 SMBIOS. Using iMacPro1,1 I get better performance with it but it is plagued with KP's like real macs that are using NAVI eGPUs.

    I am 99% sure all of my issues with kernel panics were from running iMacPro1,1 for my smbios to enable hardware encode and decoding on the Navi card. I went back to running iMac15,1 which matches my hardware better and I haven't had a KP in weeks but I loose the dgpu encoding and decoding. I am...

    Display Sleep, must unplug/replug HDMI

    My issue ended up being a USB issue. Everything is working fine using HDMI without any adapters.

    Catalina AMD 5700xt

    So far I haven’t seen anyone successful with that. I’ve tried many different options, both paid and free.

    You shouldn’t be using both the SSDT and the KEXT. It’s one or the other. In either case continue using WEG.

    Yea I have no issues viewing H.265 files, it's encoding and without HW acceleration they are only encoding at 5-10 FPS. With acceleration I was getting 200+ FPS but stability was an issue with iMacPro1,1. I have been encoding movies for my home server as H.264 for years but started doing them as...

    Thanks for the reply, that's kind of what I figured. Was hoping to have HEVC hardware acceleration using the dGPU with iMac15,1 :(.

    What’s the best SMBIOS to use with Navi and Haswell? iMacPro1,1 gives great performance as it forces videotoolbox to use the Navi card but has stability issues. iMac15,1 is very stable but I am unable to get the dGPU to be used by videotoolbox. Any suggestions?

    if you want the AMD card to show you have to changed the model in device properties to contain “AMD”. For example “AMD Radeon RX 580”.

    Here - https://www.tonymacx86.com/threads/amd-radeon-performance-enhanced-ssdt.296555/ Just had my first crash in a few days though. Funny enough I wasn't doing anything on it. I had actually stepped away for a few mins. It hadn't gone to sleep either. There is still work to be done.

    Another Sleep issue

    Unfortunately without a crash report of some sort it’s going to be trial and error.

    Another Sleep issue

    Ok, just checking because I kept hitting reset before it was KP'ing. Are you able to SSH or connect to the computer from another Mac? Have you tried unplugging and re-plugging the display? Tried other ports on the card?

    Another Sleep issue

    How long do you wait before hitting the reset button?

    Another Sleep issue

    Does it eventually KP? Mine was doing the same thing and it turned out to be a USB issue. Initially I thought it was the GPU because I had just updated the card and macOS to Catalina. After looking at the KP reports it was a USB issue.
