At this time, Instant Street Dating is only supports Windows systems. However, you can still run it on a Mac or Lunix IF you have 3rd party software installed that can emulate the Windows environment.

For the Mac:

GuestPC (http://www.lismoresystems.com) is an inexpensive emulator which can be purchased online and downloaded.

Microsoft also has a product called VirtualPC (http://www.microsoft.com/virtualpc/).

For Lunix:

http://www.vmware.com/products/player/

http://www.parallels.com/en/download/desktop/

Either will allow you to install almost any version of Windows you can get your hands on, and as long as it's Windows 98 or above, you'll be able to benefit from all of Instant Street Dating's Home Trainer.
