I'm really upset about this issue... I have a 1.9 GHz imac G5 and feel that my computer is perfectly capable. Does anyone know any way to enable the effects on a PPC mac? I want this thread to be the master thread for this issue. I was thinking if I could get a friend with an Intel mac to send me their ichat, maybe leopard installs a different version for PPC?? Also, maybe there's a way in the terminal to trick iChat (maybe a preference or system file) to think that I'm on an Intel. PLEASE give suggestions because maybe one thought will help other people or me create a full solution.
