Installed Tiger on my iMac G3 and the first time I ran iTunes it said there was an u/g to 10.6.1 available. Not convinced 10 will run on a G3 I checked the iTunes page on apple.com and, sure enough, 10.6.1 is for Intel, G4, & G5. There's a link for G3 Mac Users which says 8.2.1 is for G3s so I d/l and installed that. When I run this it still says 10.6.1 is available and do I want to d/l it. Will this actually run on a G3 or is the upgrade checker broken?
