[SOLVED] Intel® HD P530 - No graphics acceleration on Ventura

[ivak4eto]

Hello fellas!

I manage to install Ventura on Skylake laptop (Xeon E3-1505m-V5) with HD P530 iGPU.

But VRAM shows only 31 MB. I tried many different things, but no success with graphics acceleration.

I even tried OCLP 050, but it couldn't install the graphics patch for some reason.

Maybe I'm doing something wrong. I'll attach my config.plist

I would appreciate some directions!

Thank you in advance!

AFAIK P530 will not work in macOS whatever you do.

It does on Monterey.

Yes but on Monterey you don't need OCLP root patch, right? Ventura is different.

 

Look at this site, maybe it can be useful.

Thanks. I tested it already yesterday and I updated OC and kexts too, but no luck.

 

On my Broadwell laptop the root patch works, but on my Skylake laptop the root patch isn't applied for some reason.

Maybe it has to do with the OCLP itself, or device-id / platform-id.

I am not sure if I am spoofing the device-id correctly.

 

I've read on another forum about similar issue - my DVMT might have not being set.

Also I'm not sure how to repair permissions and rebuild cache (if that's going to be of help at all).

Seriously? Acceleration?

Yep - P530 has been working from Mojave to Monterey on my laptop. But for some reason it's not working on Ventura - I guess because it's unsupported now. I'm stuck at finding workaround for Ventura.

I'm typing from it now 🙂

OK, I will know that.

Poste IOREG + config.plist Monterey

config.plist MacBook Pro.ioreg

Got it working!

 

I had to go through all the platform/device ids but eventually made it work with these:

 

AAPL,ig-platform-id: 00001659

device-id: 26590000

@ivak4eto

Glad to read you. It's strange, I don't remember those ids as suitable for Skylake iGPUs but if they work for you... go ahead.

[ivak4eto]

You are right, they aren't. I had to spoof the IDs to Kaby Lake.
