• macOS Mojave
• macOS High Sierra
• macOS Sierra
• Mac OS X El Captain

Notes:

(*): macOS 12 Monterey does not support iMac15,1 or older SMBIOS, use iMac16,1 (if you only have iGPU) or iMac17,1 (if you have dGPU) and add -lilubetaall to boot-args.

(*): Apple dropped support for Kepler NVIDIA grapics card 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,...

• Bootcamp**
• You tell me.

Notes:

(*): GT730 (Kepler) is natively support in Catalina, other NVIDIA card please check before install Mojave or above.

(*): You may have screen flickering sometimes, add agdpmod=pikera in boot-arg may fix it.

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

• Because macOS don't support low-end CPUs like Pentium, Celeron, so we need a 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 to 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.
