masterli Posted November 1, 2021 Share Posted November 1, 2021 1. Firstly refer to the link 15681-precision-7510-7710-bios-settings to set up the BIOS. 2. Secondly, the AAPL and ig-platform-id of the graphics card HD530 do not work by 191B0000. When the AAPL, ig-platform-id is 191B0006, the mac system can be entered normally, but the system is very lagging. It is suspected that the graphics card is not set up properly. I am very grateful that seniors can help me to solve it. It should be noted that the config editing software I use is OC Auxiliary Tools V20211115 for OpenCore 0.7.5.

masterli Posted November 1, 2021 Author Share Posted November 1, 2021 But it doesn’t work by these Id. I guess the reason is for OC auxiliary Tools.app. Link to comment Share on other sites More sharing options...
