It also uses Hypervisor Framework for much faster speeds on the Mac: > UTM employs Apple's Hypervisor virtualization framework to run ARM64 operating systems on Apple Silicon at near native speeds. On Intel Macs, x86/x64 operating system can be virtualized. In addition, lower performance emulation is available to run x86/x64 on Apple Silicon as well as ARM64 on Intel. For developers and enthusiasts, there are dozens of other emulated processors as well including: ARM32, MIPS, PPC, and RISC-V.
