Open source software for running Windows or Linux on a Macintosh. It allows users to switch between guest PCs and restart guest PCs at any point. Q also enables users to exchange files between the host operating system and the guest.

Q is based on the excellent open source CPU emulator QEMU from Fabrice Bellard. Pierre d'Herbemont from stegefin.free.fr ported QEMU to OS X and initiated a cocoa Version. That was the initialization for Mike to develop Q. A completely rewritten cocoa port of QEMU, built directly on OS X, making use of Apples Core-technologies like Coreimage, Coreaudio and OpenGL for in- and output, saving the overhead of crossplattform APIs like SDL, FMOD or GTK.
