Hey folks! Thanks in advance for any help you can provide.
So, I'm currently working on getting MacOS running on a Precision 7530 I bought a while back. Specs as follow:
CPU: i9-8950HK
RAM: 64 GB
iGPU: UHD 630
dGPU: Quadro P2000 (which I've disabled)
Storage: 3x Samsung 970 NVME (1 dedicated to MacOS)
Wifi/Bluetooth: Some sort of Intel card; working fine.
4K LCD display
Currently it is running Monterey, but should be compatible with the newest Sonoma release (which I will update to once I've figured out this UHD issue). I've gotten just about everything to work. Thunderbolt works, wifi/bluetooth work, sound works, I've even gotten the Quadro to work via OCLP (as a stopgap).
But try as I might, I cannot get the iGPU -- which should be 100% compatible and trivially easy to get going on paper -- to work properly. No matter what I do, I'm stuck at 31MB of VRAM and unaccelerated graphics.
When working on getting the iGPU going, I disable the dGPU with -wegnoegpu (and have confirmed it is properly disabled); likewise, when working on the iGPU, I ensure I have Switchable Graphics set to On in my BIOS; otherwise the iGPU is disabled and only the dGPU is used. So, on paper, there is no reason this shouldn't be as easy as dropping in an appropriate platform-id -- it's a natively supported iGPU with a natively supported device ID (0x3E9B) on a natively supported CPU that has an exact SMBIOS match (both MacBookPro15,1 and 15,3 have 8950hk w/ UHD 630 iGPU models).
Things I have tried:
-Every compatible 8th gen UHD 630 framebuffer
-My iGPU's device-id is already 0x3E9B, but just to be safe, I tried injecting it along with the various framebuffers in addition to trying the various framebuffers on their own without a device-id entry.
-Dumping my BIOS and ensuring that DVMT Pre-Allocation was at least 64mb (it was, by default).
-Using an undocumented setup_var address to increase the DVMT PA to 128mb.
-Assorted boot flags (e.g. -cdfon, igfxonln=1, etc.)
-Assorted OpenCore device property entries, e.g. the various framebuffer patches.
-MacBookPro15,1 and MacBookPro15,3, both of which are for 8th gen CPUs with UHD 630 iGPU.
Dells are typically extremely easy to get going in my experience, but at this point, I'm about to give up; either I'm overlooking something extremely easy that I'll be kicking myself for later or there is something extremely weird going on with my system that is well outside of my wheelhouse to address.
Any ideas? I'm stumped!
