I have an iMac G4 that I've just sold and I plan to do a clean install of Tiger for the new owner. I've already deauthorized iTunes on this machine - but before I choose the 'Erase and Install' option I want make sure it is going to do what I want...which is return the machine to like new condition -- leaving no hidden files, etc. behind that might contain sensitive data. You hear horror stories all the time about Windows machines that continue to hold on to data no matter how hard you try to erase it. So what's the concensus - will this get the job done? Is there anything else anyone would advise doing before sending the machine off? Thanks - Oh, and while I'm at it -- am I correct that there is no need to reinstall Panther before Tiger (the machine is currently on 10.4.1 - I just want a clean install)?
