[ale] [OT] Upgrade G4 Mini to OS X 10.5?

[Joe Knapka]

Hi folks,

My ex-wife has a G4 Mac Mini that refuses to work with her new iPod
until it's upgraded to OSX 10.5.  Is it even possible to do this?
Apple doesn't seem to provide 10.5 for G4 machines, unless (as is
likely) I'm missing something obvious.  I also tried torrenting a
"Universal" 10.5 installation DVD, but it wouldn't boot on her
machine.

Any advice appreciated.
