Can’t Get GPU Passthrough Working on Old MacBook – Need Help!

[veryotaku]

Hi everyone,


I have an old MacBook with an integrated GeForce GT 650M GPU, and I’d like to turn it into a Proxmox server hosting a Windows 11 virtual machine. The only problem is that I can’t get the GPU passthrough to work.


Could someone tell me if my laptop is compatible? (Here’s the model link: https://support.apple.com/it-it/112568) Also, can you point me to a guide or walk me through the process? I’ve tried so many approaches, but whenever I try to add the GPU manually, the VM just won’t start anymore.


I’m not a hardcore tinkerer — I’m following online guides, but it’s not easy.


Thanks in advance!

sadly i dont think youll get much help with this device
i am no expert either but i had a vfio passthorugh set up for gaming a long time ago.
back than i used those links for reference:

the most important thing is that you get your gpu into an isolated iommu group (and a uefi that supports iommu).
there is also a patch which bypasses alot of security features and trys to brute force iommu groupings.

its called acs override:

but i think the two blog posts which also contain a lot of linked resources might be a good start in your adventure.

i wish you best of luck
