OK, so i've worked on this for a week and read every post in this thread and it's gotten me 98% there...
I can install BigSur no problem, i can change number of cores and memory, i can install opencore, i can update opencore, i can make it auto boot without picker, i can get apple ID / imessages to work, i can get virtmanager to work... i just cant get one thing to work...
GPU passthru!
I specificially picked up a GT710 because it appeared that one worked will with no hassle... i add it to unraid as a secondary card... i can pass it thru to windows vms... i just can't seem to get it to work with macinabox.
I stub it, i add it to xml file, i edit the file with the multifunction='on' bit and set the audio portion to the same thing with the function 1. I try it with no rom, i try it with a rom i flashed using SpaceInvaders tool, i try it with a rom i got from the interwebs...
I've followed every tip in this thread but it still won't show up monitor doesn't register a signal.
When i pull up virtmanager i get the following lines that i don't see when i use vnc:
OCC: Missing compatible GOP - Not Found
OCC: Missing GOP on ConOut - Unsupported
OC: Changed resolution to 1920x1080 @0 (max: 0, force: 0) from 1920x1080@32 - Unsupported
OCUI: Failed to load images
OC: External interface failure, fallback to builtin - Unsupported
Then it shows me the boot menu... and when i pick the bigsur disk i get:
OC: Boot failed - Aborted
OCB: StartImage failed - Aborted
What am i missing? Do i need to edit something in the open core config? others on the forums have said the GT710 was easy plug and play (to include SpaceInvader) which is why i picked one up for this project... did i just forget some simple setting / step?!?!
Please help me get to 100%!!!
