You can get the QEMU virtual machine to release your mouse focus by pressing CTRL + Alt + G.

Both Intel and AMD CPUs are supported, but the recommendations are Ivy Bridge (or later) Core and Xeon processors, or Ryzen and Threadripper processors (from the macOS-Simple-KVM FAQ).

See the KVM checklist from here to find out if your CPU supports this

Your computer CPU needs to support hardware virtualization.

After installing macOS in the virtual machine, the total size of the Sosumi folder ( ~/snap/sosumi) on my system is about 31,5 GB, but this can get larger as you install extra applications in the macOS virtual machine.

You can find the snap package source on GitHub. This snap package, created by Alan Pope of Canonical / Ubuntu, makes it easy to install and run macOS in a virtual machine on Debian / Ubuntu, Fedora and other Linux distributions (after installing snapd), shipping with basically everything you need to get it running. So this may not be suitable to be used for heavy tasks, but it's perfect for testing. It's worth noting from the start that Apple doesn't allow installing macOS on non-Apple hardware, so to use this legally you must have Linux installed on Apple hardware.Īfter using Sosumi for a few hours on my Ubuntu 20.04 desktop, I can tell you that the installation takes quite a while (about 50 minutes on my system), and the macOS system may be a bit slow, but it's usable. It does not ship with macOS, but downloads an installer image for macOS Catalina. Sosumi is a snap package based on macOS-Simple-KVM that makes it easy to download and install macOS in a virtual machine (is comes bundled with qemu-virgil, which includes virtio-vga, a paravirtual 3D graphics driver).
