I'm stuck at the UEFI prompt. I've tried 1.2.0 and 1.1.1 with a Ventura and a Sequoia. I am running vmware workstation v17.6.4 on linux.

Thanks for any help!

nm, figured it out. Needed to set VMWare to connect to the cdrom on power up. The install is progressing nicely! Thanks for your great work!

[tamta0]

Many thanks for your great work.
You are a blessing for the whole Hackintosh community. :) ;)

Would like to ask why VMHide got removed. It works flawlessly on my AMD Laptop.

[DrDonk]

License was checked and not allowed to redistribute it. Check out the spoofing document in docs folder. Can be achieved via a VMX setting:

hypervisor.cpuid.v0 = "FALSE"

How do I "install" 26.1 or any other mac os version? I have the interactive shell open but am stuck on how to get OS. I tried downloading ISO and putting it in the cd/dvd slot. Please help.

The opencore.iso is not in the zip

[DrDonk]

I have not released it. It's still under development.
