A few days ago, just before the end of last year, Aspyr has released the Unleashed expansion pack for the Macintosh. For reviews of the game, please check out our review index. Our own review is still to come very soon, it's been delayed because Andy was busy with Sim Brother and a lot of other things since the game has been released. You will hear about that soon enough..The Macintosh system specifications are:

MacOS 9.2.2 or Mac OS X version 10.1 or later

G3 processor at 233 MHz or faster (450 MHz recommended)

192 MB of built-in RAM (additional 128M recommended if running OSX)

2 MB VRAM (8 MB recommended)

750 MB of additional hard drive space

Quicktime 4.1.2 or later
