Santiago93 Posted November 15, 2021 Share Posted November 15, 2021 Hi, install MacOS Big Sur on my Dell latitude 5480 laptop, everything works except: -Touchpad -Display brightness keys -Ethernet I tried to solve everything from this forum but I had no success, besides that if you can help me to better organize my EFI folder and update the OpenCore version. My EFI folder, I can't upload here for the size. https://www.mediafire.com/folder/jlt7356qjhvcp/EFI Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 17, 2021 Moderators Share Posted November 17, 2021 did you press F12 and see if it shows as a boot option? You could also try going in the BIOS and create a new boot option, call USB OC or whatever, point it to /eFI/OC/Opencore.efi Then you could try select it during boot after pressing F12 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 17, 2021 Moderators Share Posted November 17, 2021 either disable it in the Config file or add AudioDxe.efi to /EFI/OC/Drivers folder Best to just disable it in the Config unless you want to add the boot sound Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 17, 2021 Moderators Share Posted November 17, 2021 Looks like a mismatch of files. I just check Baio's file, seems ok. The config file, bootx64 and Opencore.efi seems to be all from OC 0.7.5. Either you didn't copy the entire folder with all the drivers or you need to reset NVRam at the OC picker.
