@Leoyzen I’m running macinabox and ostensibly have everything working perfectly, but cannot for the life of me get hardware acceleration working for the RX580 I have passed through, despite the fact that it’s outputting a picture fine, shows up in system info fine, and I have the latest versions of Lilu and WEG installed. I’m considering killing the whole VM and building it by manually like you mentioned to see if that helps resolve the issue. Do you have any resources you’d recommend on getting started setting up the VM manually?

@solojazz Did you have similar issues when testing using VNC? If so, you might not have enough resources dedicated to the host, causing the whole system to be slow and glitchy like your seeing. Seems weird though. Have you tried a different keyboard and mouse? If it occurs with multiple, that narrows things down a bit potentially.

@pingustar The CPU topology line causes the VM to not boot. Try removing it from your XML and see if it boots up correctly: <topology sockets='1' cores='2' threads='2'/>

@infinitycell unless I’m misinterpreting your XML, it looks to me like you’re allocating all 16 of your cores (and all their hyper threads) to your macOS VM? If that’s the case, you have no performance because you need to leave some leftover for unraid as your hypervisor. Try leaving a single whole core (both threads) left over for unraid and I bet the VM preforms much better. Also be sure to leave unraid some RAM too.

@widdefmh glad to hear it! Hoping to get my issues worked out sometime soon. I think it may be related to power draw. I have one PCI power cable coming out of my PSU with 2 4 pin power headers on it. I believe it’s meant to power a single card with an 8 pin connector, not two cards each with a 4 pin connector. Both GPU’s work and drive screens at full res, but I think it’s affecting performance under the hood. Gotta dig up the modular cables for my PSU and give both cards a dedicated cable. Really hoping this is it, because software wise everything seems perfect.

Double check your XML. If it’s just a black screen, you likely forgot to remove the CPU topology line when you modified the VM in the GUI. Easy mistake. If it’s not that, or a failure to manually make the couple other changes you have to make to the XML every time you change a setting in the VM manager GUI, I’m not sure.

I’ve successfully setup a Catalina VM using macinabox and it all works great. My host is running on a 3950X with a GTX 1080 for a Windows VM, and a Sapphire Pulse RX 580 configured for macOS pass through. I’m having an issue related to GPU psd through. The GPU functions perfectly, except that hardware acceleration seems to be completely botched. The RX580 shows up in system info no problem, but does not have metal acceleration listed. Chrome (and chromium based apps like discord, Spotify, etc) all exhibit very odd graphical errors unless hardware acceleration is turned off. I used a video editing program called Video Proc, which has a setting page for easily checking hardware acceleration status, and everything showed up as blank. I’ve rebuilt the VM from scratch several times and the same issue always comes up, even as the rest of the VM works flawlessly. I’ve tried changing the smbios to iMac Pro 1,1, and verified that I’m running the latest versions of Lilu and WEG kexts in clover configuration. I’m really not sure what else to try at this point. Any ideas would be appreciated. I don’t currently have access to my VM’s XML template, I’ll be updating this post with it shortly.

@widdefmh it’s definitely easier with AMD cards, though a lot of them suffer from the reset bug which can be a pain.

@phyzical are you asking how to run virtualization software inside your macOS VM? Like parallels or VMware software? Or are you having difficulty getting the macOS vm working? If the latter, watch this video and follow steps by step, should be helpful:

@SpaceInvaderOne Thanks a bunch for this! I'm working on getting this up and running on my Unraid box and kept running into an issue when I'd try to add CPU cores. I didnt catch that these lines were being altered when I reset as the video did not mention them and I was not observant enough on my own. I was just about to run a diff between a copy of the original XML and its altered state after applying in form view when I found this comment. Saved the day! Or, at least, a lot of time
