Hey Wai Lee I have OSX 10.2.6 running on an original tangerine ibook and it works nicely .. Especially for the apps you list down there .. I am not sure about the HD space and the RAM though ..

But at least I can give you some hope that it works in general Greetings from Sydney P __________________________ http://nackentravel.blogspot.com __________________________ on 6/16/03 7:36 AM, Spike T Frog at SpikeTheFrog at attbi.com wrote: > Hi, > > I am looking to upgrade my other ibook, an original tangerine version, > up to OS X.
