No GPU passthrough in MacOS guest ?

[neesoe]

I have been trying to run some apps and the graphics seem to be non existent . Apple system report shows null for Graphics/Display. I am curious if this is even possible with the current virtualization.framework . Thanks

Hi @neesoe, paravirtualized GPU performance and compatibility highly depend on versions of macOS on your host and in your guest. Please make sure they are as fresh as possible. For example, #501 were just recently supported.

I tried it multiple times.Everything is set to the latest and the guest mac system report for the Graphics still says 'No information found'.

Where exactly do you see "No information found" message?

[neesoe]

System settings -> General -> System report -> Graphics/Displays under Hardware <img width="1136" alt="Image" src="https://github.com/user-attachments/assets/a777f248-e3a1-4b69-b3af-dcfb38310d2a" />

Update - It seems like paravirtualized graphics is available but it does not appear to help with apps. I tried a couple of apps and they all go haywire when doing anything 3d. Just for curiosity I did a Geekbench for metal and it scores over 30K which is 90% of what the host system gets. I am utterly confused

[neesoe]

Activity manager in the host os does show many processes that suggest graphics is available but apps inside the guest are not able to use them for some reason. Since the Geekbench score for metal is pretty good I am not able to understand why apps won't use it.

For now the workaround is to use the Apps with disabled hardware acceleration. In the first app(Archicad from Graphisoft) smaller projects open fine and is usable. Bigger projects are lagging a bit , but still usable. The other app(sketchup from Trimble) does not have any options to disable hardware acceleration and is totally unusable.

I am still very surprised this works so good even with a MacBook Air with 8GB of ram. Shame the graphics is acting up.
