G5 crashes on launch

[oi41]

I have just bought a G5 with OSX 10.2.7 (now upgraded to 10.2.8). As soon as I launch ProTools (6.1.2), the computer crashes and requires me to hold the start button down for 5 seconds to relaunch.

Previously I had 10.2.7 and 6.1 and it actually launched ProTools, but crashed when I tried to create a session or enter any other screen.

The G5 shipped with 10.2.7 (refurbished), but I now wonder if installing 6.1.2 is incompatible and this is causing the crash. Could anybody offer advice on this.

Kind regards, Richard (London)

If you have a G5, you must be running 6.2.3 (or later) on OS 10.3.2. G5's were not supported on OS's earlier than 10.3.

I have since updated my G5 to 10.3 (Panther) and 6.2.2 and all is fine. Clearly, 6.1 and G5 (10.2.8) do not mix!
