Not that it matters much at this point (I imagine), but the Apple guy said there was something like archive and reinstall. There's nothing on this iMac that remotely resembles such an application. Nor in Finder's Help.

As long as I'm at it, how does one burn CDs and DVDs on this machine.
Again no instructions available (at least not where I can find/see them).

And the day started out so auspiciously, with smoother sailing and all. How quickly it all turns back to crap. The depression and neck muscle twinges are coming back with a vengeance.
