Leopard OSX 10.5 Notes: The latest OSX version from Apple has some fairly high requirements. If you are bent on running it the QuickSilver models below that feature 867mhz processors or better will run Leopard. The G4 Sawtooth and Digital Audio models below that will run Leopard on models above 867 mhz. The DVD software however requires a better video card be added to those models for playback. We have Video Cards for either units that give you much improved performance call and ask. Read Bob's Mac Tech Tips for more information about Leopard on older hardware.

We have added SYS ratings. This is Norton Sys Info numbers for the system's performance as configured. They are for comparison info only and weights CPU, FPU, Graphics and Drive Performance to determine an overall average performance level. Your results may vary. We will fill in the numbers as time for testing allows.
