We have a drop-down menu of volumes in our UI, and I'd like to update it when a new disk is mounted. In the Classic days, this would involve watching for a diskEvt event. In Carbon, I think this was kEventClassVolume. What's the Cocoa equivalent?
(A pointer into Apple's documentation on this would satisfy the question. I've been unable to find anything!)
