Running MAC OS in a VM

How to install for virtual box:
(mostly tutorials mention the same steps)

- It is important to match the .iso file and the commands, since they seem to be device and OS specific.
- Also, CLOSE virtual box software when running the commands.. :P don't know why...

I used this iso and code combo:
https://www.wikigain.com/how-to-install-macos-big-sur-on-virtualbox-on-windows-pc/

The code to be run:
http://www.mediafire.com/file/k0nkr3aomk4pgts/VBox_Code.txt/file
The iso file:
https://download2389.mediafire.com/kkieo4bid9rg/vuxhn73malcin7w/macOS+Big+Sur+Beta+11.0+%2820A5343j%29.iso
(don't know how long this will be available)

sample code to modify the VM's properties to spoof the software into thinking it is compatible machine:

VBoxManage.exe modifyvm "macOS Big Sur" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "macOS Big Sur" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
VBoxManage setextradata "macOS Big Sur" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "macOS Big Sur" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
VBoxManage setextradata "macOS Big Sur" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "macOS Big Sur" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1
VBoxManage modifyvm "macOS Big Sur" --cpu-profile "Intel Xeon X5482 3.20GHz"

Note: You should replace your "VM Name" with your own virtual Machine
Code for Virtualbox 6.x:
