iCanaro Posted August 13, 2022 Share Posted August 13, 2022 add boot-arg -igfxvesa 1 1 Quote Link to comment Share on other sites More sharing options...
donbish Posted August 13, 2022 Author Share Posted August 13, 2022 That worked great. I was able to install everything and boot ok. However, now the igpu is not rendering at full resolution. About Mac says there is only 2mb. How do I get full resolution and not need the -igfxvesa boot arg? Quote Link to comment Share on other sites More sharing options...
iCanaro Posted August 13, 2022 Share Posted August 13, 2022 now that you have installed it, you will need to find the right framebuffer of your UHD630 to enable full graphics acceleration https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md 1 Quote Link to comment Share on other sites More sharing options...
iCanaro Posted August 13, 2022 Share Posted August 13, 2022 PS: remember to remove -igfxvesa 1 Quote Link to comment Share on other sites More sharing options...
donbish Posted August 15, 2022 Author Share Posted August 15, 2022 Thank you. I managed to set the correct framebuffer and device ID. Removed the -igfxvesa boot arg and everything is working fine. I copied my EFI folder from the installation USB to the internal HDD where MacOS is installed. Booted into the OS and loads fine, greeted with the log in screen, however mouse and keyboard does not work? It works fine if I boot opencore via USB installation but not via internal HDD.

iCanaro Posted August 15, 2022 Share Posted August 15, 2022 kernel -> add disables 2 kext related to usb kernel -> quirks enable xchiportlimit if it works and you have all usb ports working, then you will need to map and disable xchiportlimit https://aplus.rs/2020/usb-mapping-how/ 1 Quote Link to comment Share on other sites More sharing options...
