ok so heres the problem.
i've got a G3 ibook with mac OSX v 10.2.1 insalled. i want to download a softwear update for the ibook so that i can run a standard photoshop program. i've downloaded OSX v 10.4 from a windows p.c to an external hardrive and then tried to upload it onto the ibook but it doesn't seem to work, it firstly tries to open the program and then tells me it does not have the access codes required then tells me it incountered an error.
i was wondering if anyone has a soloution to this problem or knows a version of photoshop that would work with this model of ibook.
