I bought my mbp and am no longer in need of my 12" ibook g4. I've cleaned it up nice and shiny and I want to sell it but am not 100% sure I took all the right steps to get the highest price and to make sure I give someone a perfect system. Here's everything: Specs: 12" iBook G4 800Ghz, 640MB ram, 60HD, Airport express, 24x combo drive. New HD installed about a little over a year ago and new battery in January. The CD-rom drive sticks a bit when inserting and ejecting discs, but is perfectly functional. Besides minor expected cosmetic damage, everything works 100%. So far, I formatted the HD and installed OSX. When I turn the computer on, it goes to the welcome screen and asks to register OSX. A few questions: 1. I got the copy of OSX from my ADC membership. Can I still install OSX on my other macs, even if the buyer registers with apple? 2. Do I need to take anymore steps for OSX to work? register with my name, or with generic names, etc? 3. How much can I expect on ebay? Or is ebay not the best place to sell? 4. What else should I do to prepare it for sale? 5. Any other advice would be much appreciated!
