Here's my setup: I have both a 13" non-retina MBP and a 15" Haswell rMBP, both running Mavericks. I also have a Thunderbolt display. When I connect the display to either laptop, I like have the TB display show pictures from one iPhoto album (a bunch of album cover art spoofs) and another album (my niece). When I disconnect the TB display, the MBP's display changes the the cover art spoofs. So I change it back to my niece. When I reconnect my TB display, both display my niece album. Is there a way for my laptops to remember what to show on each display when connecting/disconnecting the display?
