I have got my daughters very old ibook. (The bulky white one!) 2 questions. Its Mac OSX Version 10.4.11 Memory 512 Processor 1.33 ghz I would like to clear the whole computer (back all her stuff onto an external HD) Then just use the computer for Garage Band. (With a keyboard and amplifier.) My question is... How do I back up everything to the HD How do I clear the computer back to nothing but the apps ie factory settings Can I update Garageband on this system? And if not am I missing out on much by not having an up to date version THANKS!
