YouTube is heavy on the computer, unfortunately it's as simple as that. You can improve the display by not using full-screen mode, and by using a low-resolution alternative stream as pointed out by the other posters. Or see if you can increase the computer's RAM, and maybe install a clean OS.
Re. overclocking: that is not for the faint at heart. It means changing something to the hardware, or deep inside the operating system, to make the processor run faster than its tested maximum speed. In practice, that will give you 1. something like a 10% speed boost and 2. more system crashes. A more realistic thing would be to replace the processor by a faster one, but as far as I know that can't be done in iMacs. (Please correct me, anyone.) Somehow your post sounds as if he is used to a different computer and/ or a different internet connection where everything goes smooth. Yes, there are cheap Windows-boxes playing YouTube better than this iMac. What to do? You could tell him that Macs are for being creative, not for consuming tons of YouTube crap... -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
