Oli.mathieu Posted November 28, 2020 Share Posted November 28, 2020 (edited) Hello everyone It's known that "big sur" installation is not possible without NVRAM Unfortunately I have never managed (even with Opencore guide) to get NVRAM work. Here is my SSDT and my ACPI folder Any help would be much appreciated Thanks in advance X299 Creaor - System DSDT.dsl.zip ACPI.zip Edited November 30, 2020 by Oli.mathieu Link to comment Share on other sites More sharing options...
