to low to use blender 3.43 ..the latest version i think - the processor and ram I have should be fine I have mac OS 10.2.8 - though I can't see myself on a 10.4.x anytime soon. I have an old E-mac ( and i'll ask about updating it in the mac forum)- I'm basicly looking for an earlier version of the program so that i can learn it by the time i upgrade both blender and my current system. knowing at the rate things are going blender will be version 6 by then...
