So i installed bigsur and it works as it should, with vnc. When i add my quadro K600, which should be supported, it boots until i come to the login screen but i only can see the background and nothing else... nothing to actually login... keyboard works on boot...

 

any idea what the problem is?

Are you following dortania instructions?

https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/nvidia-gpu.html#kepler-series-gtx-6xx-7xx

 

Try to add in your config.plist, boot args:

shikigva=40 shiki-id=Mac-27ADBB7B4CEE8E61

 

Append them if you have others, follows example:

 

	<key>NVRAM</key>
	<dict>
		<key>Add</key>
		<dict>
			.......
			.......

			<key>7C436110-AB2A-4BBB-A880-FE41995C9F82</key>
			<dict>
				.......
				.......

				<key>boot-args</key>
				<string>shikigva=40 shiki-id=Mac-27ADBB7B4CEE8E61</string>

i tried vnc and gpu secound at first, then only gpu, then vnc and gpu again, then only vnc (had to fix bus in xml to get it working again)

 MacOS already thinks its a macpro 15.1, should i switch that to a imac 14.2?

did a fresh install and the mac as an imac 14.2 and it works great with the quadro k600! thanks!

now i have to figure out how to get rid of that boot screen at the start, so it boots right away...

Sorry for the delay. I never played with shiki but I think you don't need to spoof the whole vm to imac 14,2: shiki-id should spoof to imac 14,2 only for the gpu.

Anyway, if it works and you are satisfied, it's ok.

what boot screen are you referring?
