Hi, My 12 inch G4 power book, which I bought 3 years ago did not have an airport card so I bought one two days ago. However, the software program that came with it does not install on the computer because I have OS X v 10.2.8 and the software will only install on OS X v 10.3. I downloaded the older version of that software but that still does not work. Also,I went to system preferences,and tried to find the airport in the network but I could not find it. Do I have to buy the new OS X or is there a way to make this work without doing that? Thanks!
