How to Get Mountain Lion to Use an Already Existing Time Machine Backup

Almost nothing is more frustrating than spending two days keeping your Macbook laptop in one location while it does a first-time Time Machine backup to your Time Capsule – especially when it’s not really a first-time backup, because you already have a perfectly good backup on your Time Capsule but your Macbook Air or Macbook Pro won’t recognize it, so it starts all over.

And then, when you hit “rescan” it can’t find the Apple Time Capsule at all, even though it had just found it moments before? Here’s what to do.
