Finding things in Finder · Moved and offloaded apps in Finder
How do I see where a moved app actually lives on my external drive?
Short answer: Open the Apps window's Moved tab: each app shows its destination, and Reveal in Finder opens the app on the external drive. Or select its shortcut in Applications and choose File → Show Original.
Open the Apps window's Moved tab. Each moved app is listed with the date it moved and its destination on the drive, and Reveal in Finder opens Finder at the app itself on the external drive — not the shortcut in Applications.
From Finder you can also select the app's shortcut in Applications and choose File → Show Original.
Leave the app where it is on the drive. To bring it home, use Move back in the Moved tab, which restores it to exactly the folder it came from.
