Hi I'm totally unfamiliar with ibook. I bought this ibook with no CD's and I want to start over with a totally fresh install. There is an administrator account on as well as my account. What OS discs can I consider? I've been looking on e-bay. Or am I limited to what I already have installed? I just can't install stuff like my USB wireless and frostwire, as well as optional browsers, etc. Thanks Some HELP in posting on Computing.net plus free progs and instructions Cheers

You can use any Mac OS up to and including the latest version, 10.5 Leopard. I'd limit my choices to 10.3 or higher. Before ordering any system though, check and make sure your iBook has a DVD capable drive or you'll need to do a little extra searching to find the OS on CD, and I'm not sure you can get 10.5 on CD.

Thankyou golpher, My optical drive is from what I can see a CDR/DVD combo. So If I get the new Install CD or DVD I will be able to reformat and re-install without worrying about the previous administrator log-in password? Thanks

Yep. Once you get past the language screen, under the Utilities menu in the menu bar select Disc Utilities. Once it is open select the internal drive on the right side and then reformat the drive HFS+. Once that is done quit Disc Utilities and continue with installation process.

Thanks a million! I appreciate your info!

I have a mac mini ppc running 10.4.11 and classic. I have an iBook (Tangerine) running 9.2.2. I have both the original boot disks for the mini and a downloaded version of OS X on the mini's desktop (a .dmg file that an OS<10 can't use). The Tangerine has a CD drive but not DVD. The system profiler says it's working on a G3 processor and 300MHz. How can I get OS X onto the Tangerine? I know, once it's there, I will likely need some memory and processor upgrades - suggestion on what to add and even where best to get them, would be much appreciated - but first I need to get the OS right. Haaaaaalp!

Golfer is only correct if the 900MHz iBook is a G4 one. There are G3's of that flavour, and to the best of my knowledge Mac OS X 10.5 Leopard requires a G4 processor, 867MHz or better. I think Tiger is your best bet. Medion MIM 2080 Toshiba T2130CT Macintosh Performa 450 All working wonderfully.
