I’ve made a front end for QEMU in SwiftUI that works on Intel and M1 Macs. QEMU works both for emulation (running x86 on Apple Silicon and vice versa so you can run Windows 7 on your M1 Mac or Debian ARM on your Intel Mac) and virtualization (it’s faster to run the same architecture such as Ubuntu ARM on Apple Silicon).
It is completely free and open source but the Mac App Store version costs $10. The free and App Store versions are identical and the only feature you get with the App Store version is automatic updates. You’re welcome to use the free version as much as you want and you can purchase the App Store version if you have the means and wish to support the development.
