Notes:

(**): Apple dropped support for Kepler NVIDIA graphics cards since Monterey Beta 7, so you need be cautious, if you in Monterey < Beta 6, don't update to Beta 7 or just go back to earlier version like Big Sur, Catalina,...

(**): If Bootcamp don't work in your machine, you need select another OS disk in UEFI settings to boot another OS.

Guide for low-end CPUs

• Because macOS doesn't provide support for low-end CPUs like Pentium, Celeron, so we need to use the Fake CPUID and some changes, patches for that CPU to boot in MacOS:

Tutorial:

• In your config.plist, goto Kernel > Emulate add these data into required value

Cpuid1Data: A9060300 00000000 00000000 00000000
Cpuid1Mask: FFFFFFFF 00000000 00000000 00000000

• Set Kernel > Emulate > DummyPowerManagement to Enabled/True
• Set NVRAM > WriteFlash to Disabled/False
• Replace HFSPlus.efi with HFSPlusLegacy.efi
• Don't forget to take an OC Snapshot in ProperTree after you work with files!
• Some problem are described/fix like this Reddit post.
