Run macOS on QEMU/KVM. With OpenCore + Big Sur + Monterey support now! Only commercial (paid) support is available now to avoid spammy issues. No Mac system is required.

Update: Try this instead https://www.linuxuprising.com/2021/03/install-macos-big-sur-or-catalina-in.html and https://github.com/sickcodes/Docker-OSX
