I was given an iBook 1.42 GHz , Powerbook6,7 and would like to upgrade to Leopard 10.5 from 10.4.11 but have not been able to find where I might be able to obtain a legitimate copy of the universal release. So far my Google-fu has been useless. Do any of you have any suggestions on how to solve my dilemma? I apologize for making my first post a cry for help.
