Processor: Power Mac G4
RAM: 256 MB (512 MB recommended)
Operating System: Mac OS X Version 10.2 or later

However, SX will also run properly on Power Macs with a G3 CPU (e.g. iMacs and iBooks). Generally it can be said that a specific Power Mac is suitable for running SX when the global performance of OS X (10.2) is satisfying.

A very important factor for the performance of OS X (10.2) is the graphics card. If OS X (10.2) behaves rather slow on your Mac check if the graphics card you're using supports Quartz Extreme, the "composite windowing system" of Mac OS X that has been introduced with Jaguar (10.2).
Quartz Extreme's functionality is supported by the following video GPUs: NVIDIA GeForce2 MX, GeForce3, GeForce4 MX, or GeForce4 Ti or any AGP-based ATI RADEON GPU. A minimum of 16MB VRAM is required.

The use of an according graphics card increases the global performance of OS X (10.2) considerably.
