Or should i just pull the HDD from the older iBook and just run the above on the iBook G4's? What's the best way to factory reset these things without a Mac OS X disc? Only 1 of these machines has some semi-sensitive info on it (the older iBook), the others probably not so much add user, select time/date etc.)īut i do not think the above necessarily properly wipes the HDD?
