Moderators Jake Lo Posted August 16, 2020 Moderators Share Posted August 16, 2020 Do you have these issues on other MacOS? Not sure if this is available on your BIOS, but disable 'Legacy Option ROMS' if available. You can also post your file for review including an IOREG file Link to comment Share on other sites More sharing options...
