Hi Fab,
Thanks for your interest in MIR.
Right now, Vienna MIR is a Windows Vista/7 64-bit application only, and it hosts VI / VST / VSTi plugins. We have plans to release MIR for OSX as soon as we could overcome the hurdles we still encounter on this platform. There's no release date I could tell you.
For the time being, BootCamp might be the way to go on a Mac. Be aware, though, that MIR has very high demands regarding the hardware (both CPU and available RAM ... 12 GB is a good amount for medium-sized arrangements).
