I've downloaded every update for my iMac that's been published from Apple. Repaired Permissions before and after installing. Never had a problem until now. This one has proven to be a real pain in the ass.

My connections fell off, dropped out, disappeared all together, et.al. Finally did an Archive and Install to rid myself of it. I don't understand why you can't roll-back updates to the Extreme Card, like you can with the Extreme Base Station.

Or maybe Apple just wants to sell more external hard drives and Time Machine software?
