So my 6 year old sister is using an old iBook G4 to play her computer games....however she wants to FaceTime or video chat somehow with my other sister who is not at home! We have a USB webcam and the iBook G4...from what I understand you don't need an intel processor to video chat but I'm stumped on how to get this working! iChat says no camera is plugged in and there is no FaceTime natively on the computer. Its running OS X 10.5. Advice?
