For example you can't use Intel Kernel extensions, Virtual Machine apps that virtualize x86_64 computer platforms (Parallels for example), or AVX/AVX2/AVX512 vector instructions.

Rosetta 2 has a number of significant limitations. However, the translation process takes time, so users might perceive that translated apps launch or run more slowly at times. Emulating Windows XP x86 under M1 Mac via UTM & QEMU While VMWare does not. When translation finishes, the system launches the translated executable in place of the original. When I saw qemu/utm on m1 mac, I was wondering how hard it would be to run. If an executable contains only Intel instructions, macOS automatically launches Rosetta and begins the translation process. Once translated, the application is in effect a native arm64 binary making native macOS system calls. The entire binary is translated from x86 to Apple Silicon and launched. Rosetta 2Īpple's emulation, on the other hand, happens before the application launches. You can run most any Intel Operating System and associated applications. This post explains how to run OL9 as a guest on the M1 Mac, accelerated by the MacOS hypervisor framework. Several webpages such as How to run Windows 10 on ARM or Ubuntu for ARM64 in QEMU on Apple Silicon Mac and QEMU on M1 Mac describe how to set up a QEMU environment with Alex's patch. There are generally few limitations to QEMU's Intel emulation. The combination of QEMU and Alexander Graf's amework support patch allows us to run Windows 10 and Linux for 64-bit ARM processors on M1 Mac efficiently. From the Linux kernel down to your /bin/ls command. With this framework, it emulates every instruction doing everything with Just in Time translation. In order to emulate a a Linux system, QEMU must also emulate storage devices, console output devices, ethernet devices, keyboards, and the entire CPU.

However, they tackle the problem in vastly different ways.
