UEFI Variables

In order to run macOS successfully a number of EFI BIOS variables need to be modified. The included Clover bootloader contains an updated DVMT.efi, which includes a setup_var command to help do just that.

DVMT.efi can be launched from Clover directly by renaming it to Shell64U.efi in the tools folder.

The following variables need to be updated:

Modify DVMT variable step

1. Start up and enter Clover boot menu, select Start UEFI shell 64 and enter.

   I has replace Shell64U.efi with DVMT.efi, so you are running DVMT.efi in fact.

2. just run setup_var 0x350 0x4 using this cmd line 中文教程
3. fine, the graphics is ok to boot up macOS
4. Note: the UEFI Variables will lose after set BOIS to factory default!

FAQ

1. SIP enable default ?

   Yes. It way enabled by “config.plist/RtVariables/CsrActiveConfig=0x11”.

2. What should we do before install macOS system upgrade ? eg.upgrade from 10.14.4 to 10.14.5

   Maybe you need to disable SIP before doing upgrade: Set “config.plist/RtVariables/CsrActiveConfig=0x67”.
