I recently aquired a 500 mhz g3 iBook. I am currently running 10.2.. I own 10.2,10.3 and 10.4. I would love to upgrade to 10.3 but the disc has a scratch on it and wont install properly. Any suggestions for that???? Also, I would love to run 10.4 but the iBook has no DVD drive. I've read some stories about installing it from another computer (such as my iMac), but I'm a little skeptic. How will the performance be? And will the install go smoothly and continue to run smoothly? What about potential hardware issues? I have to upgrade from 10.2 because some of the apps we need have to run in 10.3 or higher. Help me out here folks!!! What should I do???
