Hi I have an old G4 eMac with an 800 MHz processor, it's still using panther. The computer will not recognize my iPhone and I can not upload raw images from my digital camera. I understand that I need iPhoto 6 and osx 10.4 for the iPhone. I only use this computer for music and simple photo manipulation. If I get these upgrades will my computer accept them or has my camera and phone made my old computer obsolete?
