Hi. I'm getting some mixed info between the folks at the Apple store and the "specialist" at an independent Mac service company and am hoping someone can clear up some of this info for me. First, I recently brought my old G4 Powerbook into the apple store hoping to upgrade it to Leopard (it's currently Panther). The sales guy, not one of the "geniuses," tells me that my machinebecause it is not intel-basedis not capable of being upgraded to Leopard and they no longer sell copies of Tiger. Then, I go to an independent mac specialist place where the guy there tells me sure he can upgrade it to Tiger for me, but 1. my machine actually can be upgraded to Leopard, and 2. that he wouldn't recommend me doing it myself as it can be problematic if I have any corrupt files on my machine resulting in very costly repair. So the point is, do I believe the Apple store guy and still only do the upgrade to Tiger or do I believe the specialist guy and buy Leopard? Also, do I have him install it or is he just giving me a sales pitch for his services? I've never experienced anything being difficult to install on a Mac and can't believe that this would be any different. And last but not least, should I avoid running Leopard on this machine completely? As I was trying to find out the answers to the previous questions, I've run across numerous posts and articles about people having problems with Leopard on various older machines though I couldn't find anything about my model in particular. If it matters, here are my machine's specs: V 10.3.9 1.33 GHz PPC G4 1GB DDR SDRAM Any help is greatly appreciated. Thank you!
