UTM is a full featured system emulator and virtual machine host for iOS and macOS. It is based off of QEMU. In short, it allows you to run Windows, Linux, and more on your Mac, iPhone, and iPad.
UTM employs Apple's Hypervisor virtualization framework to run ARM64 operating systems on Apple Silicon at near native speeds.
Run multiple instances of macOS (Monterey or higher) on your Apple Silicon Mac with UTM. This can be useful for developers as well as security conscious users.
UTM looks and feels like a Mac app with all the privacy and security features you expect as well.
While QEMU is powerful, it can be difficult to set up and configure with its plethora of command line options and flags. UTM is designed to give users the flexibility of QEMU without the steep learning curve that comes with it.
