Zia-Ur-Rehman Posted January 7, 2020 Share Posted January 7, 2020 I have succesfully install MacOS Catalina in Dell M4800.But when I shutdown or restart the laptop the bios resets the "SWITCHABLE GRAPHICS" option I want to turn this option on because this options disable the Nvidia M1100 and uses Intel HD4600.Nvidia M1100 is not supported in Catalian.PLEASE HELP.

Administrators Hervé Posted January 7, 2020 Administrators Share Posted January 7, 2020 Why don't you try the Clover RTC Fix (both in ACPI fix and Kernel & kexts patches sections). NB: no double/multiple posts on the forum please. Link to comment Share on other sites More sharing options...
