rgomez Posted October 28, 2020 Share Posted October 28, 2020 Hi, I’ve used this EFI folder to perform Big Sur Beta 11 installation and seems to be almost perfect. I notice a bit more slowness compared to Catalina. Could be because it’s Beta or either there is some issue because I experience very slow boot. Also important to refer I have HD 520 instead of HD 620. Thanks in advance, Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 28, 2020 Moderators Share Posted October 28, 2020 You need to change the ig-platform-id to HD520 instead of using the default for HD620; change 00001B59 to 00001B19, and deviceID from 16590000 to 16190000 and SMBIOS from MBP14,1 to MBP13,1.

rgomez Posted October 28, 2020 Share Posted October 28, 2020 The ig-platform-id didn't really match with what you said. The SMBIOS seems to have changed properly. But the graphics are only in VESA mode. I'm using OpenCore Configurator and the settings I had under DeviceProperties were, AAPL,ig-platform-id - DATA - 09001659 device-id - DATA - 16590000 I changed to, AAPL,ig-platform-id - DATA - 09001619 device-id - DATA - 16190000 Is it correct?

Administrators Hervé Posted October 28, 2020 Administrators Share Posted October 28, 2020 No, Jake gave you the correct values to reflect your Skylake iGPU rather than the Kabylake iGPU of the OP. Use them. Link to comment Share on other sites More sharing options...
rgomez Posted October 28, 2020 Share Posted October 28, 2020 Ok, I can confirm after typing exactly as mentioned works perfect Many thanks, Link to comment Share on other sites More sharing options...
