I have a volume (saved as an encrypted sparsebundle) that I use from time to time. For security reasons it should be ejected when not in use. Of course I should do it myself, and usually I remember. But not always. Is there an automated way to do this as a back-up for fallible me?
Maybe a Folder Action attached to it that will eject it after a certain length of time (or even better, a certain length of time idle) or at a certain time of day?
Maybe a way to have it automatically ejected when the computer sleeps? Currently, it is still there after computer sleep. (I don't want to use logout because there are other processes I want to keep going.)
