OC DELL Latitude E6420

I assume I need to install High Sierra Install FIRST* I mean I dont know how my old configuration worked my laptops just black screening or rebooting its the same series the Dell Latitude E64xx 65xx SandyBridge , I have HAD it working before.... also is the freezing/rebooting due to CFGLOCK? I read somewhere that has to be disabled using a custom grub-efi-tool loaded through clover... both of them are doing it my 6420 and 6520 Select Install Mac OS Monterey , Black Screen.... I saw you said dont install it on EFI Partition. I dont know if booting it was an issue for you The EFI Part... You can Make Disk on MacOS but then you have to install EFI delete the partition in Linux.. and make a 16MB Bios_Boot Partition and your Efi with the Remaining Free Space.. it'll show you you can Uncheck macUSB HFS+ as boot-esp and re-select EFI Fat32 just Re-COPY over the EFI and it won't Freeze when you go to Browse Files... but I still get either a black screen or it just Restarts, Hangs at a black screen or a RTC or KEXT Error or Info.plist Missing error and Restarts Anyway..

Ok so I have the DSDT/SSDTs Compiled Error Free for the E6420 I spent all night fixing errors.....

he says start with High Sierra you wont get that far you want MyHack Mavericks..

EFI macintosh makes me set up a bios_block 16mb and a 128mb EFI partition on Linux using cfdisk then just copy the EFI back:

The SSDT just has TPM , CPU, and Graphics Related Things: Ports: you need all 4...
