JackFromVietNam Posted October 22, 2020 Share Posted October 22, 2020 I have installed catalina 10.15.7, can I use the EFI directory posted for Big Sur in this thread to update me? Because LAN, keyboard, trackpad, USB 3.0 port is not working at this time. I just have the USB 2.0 port in the back working. I try to use Hackintool or Kext Utility to add all kext but it fails. Any advice for me at this time? Thanks for your answer. Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 22, 2020 Moderators Share Posted October 22, 2020 Yes, it should be backward compatible to Catalina. 1 Quote Link to comment Share on other sites More sharing options...
JackFromVietNam Posted October 23, 2020 Author Share Posted October 23, 2020 I tried and succeeded. But the keyboard and touchpad are not working. 3.5 audio jack when I plug in, play the sound for 1 second then silence. I tried to update VoodooPS2Controller.kext in Library / Extensions using hackintool or Kext Utility but it failed. Can you give me some advice?

Moderators Jake Lo Posted October 23, 2020 Moderators Share Posted October 23, 2020 Replace the VoodooPS2 with this one. Shouldn't need to be in /L/E Add CodecCommander.kext to kexts folder, make sure to add it to Config.plist under Kernel Quote Link to comment Share on other sites More sharing options...
