René Rhéaume Posted August 3, 2022 Share Posted August 3, 2022 Hello, I installed macOS Big Sur 11.6.8 on a Lenovo Thinkcentre M93p Tiny (about the same physical size as a Mac Mini) having its stock Core i5-4570T CPU only Intel HD 4600 integrated graphics in Firmware settings, minimum VRAM is set to 64MB and limit is set to Maximum. Also, VT-d is disabled. and 3 display outputs : VGA, HDMI and DisplayPort For macOS installation, I used the Haswell Notebook (the Desktop variant crashes) EFI folder from this site for my installer USB key, then added the -igfxvesa boot-arg to its OpenCore config.plist . After installation, I was able to make it bootable without the USB key. However, graphics acceleration is disabled, making any software having Chromium-based code, such Google Chrome, Microsoft Edge and Visual Studio Code, unusable. On VGA, I am limited to a 1280x1024 resolution, and removing the -igfxvesa option changes nothing (same limitations as before, but no worsening) About This Mac reports Intel HD 4600 Graphics with only 5 MB of VRAM I read on other forums you must not use VGA output for this hardware on macOS. So I stopped using it. On HDMI, I can go up to 1920x1200 (yes, that's an older 27" 16:10 monitor), but still no acceleration About This Mac reports Intel HD 4600 Graphics with 8 MB of VRAM The above mentionned apps are still unusable. I have not tried DisplayPort yet as I must get a DisplayPort cable. My questions are : Can I get graphics acceleration with the HDMI output? How do I enable graphics acceleration? No problem with purchasing a DisplayPort cable. Thank you in advance. Quote Link to comment Share on other sites More sharing options...

René Rhéaume Posted August 4, 2022 Author Share Posted August 4, 2022 (edited) I tried the patch and I get the same result as before. That is, using the HDMI output. Edited August 4, 2022 by René Rhéaume Adding a precision Quote Link to comment Share on other sites More sharing options...

René Rhéaume Posted August 5, 2022 Author Share Posted August 5, 2022 Using a DisplayPort cable instead of an HDMI one changed nothing Unfortunately, what datafeedexpert posted did not improve the situation. Looking the WhateverGreen Intel FAQ, there is a line about STOLEN memory. Where and when this line is outputted to the console? I can't see it.

René Rhéaume Posted September 5, 2022 Author Share Posted September 5, 2022 OK, the problem was I was editing the wrong config.plist, i.e. not the one effectively used by OpenCore. When I understood that, I simply had to change the platform ID in the config.plist file inside the hidden ESP partition that I mounted with ESP Mounter Pro. Thanks nevertheless.
