Apps · App updates after a move
Why is a moved app asking for my password to "add a new helper tool"?
Short answer: It's the app's own updater, not Storage Studio, and it can't finish while your fast drive is unplugged. Click Cancel, then reconnect the drive or move the app back.
That prompt comes from the app's own updater, not from Storage Studio. It usually appears when an app you moved is open while your fast drive is disconnected — the updater can't reach the app's files, so it can't finish.
It's safe to click Cancel. Then either reconnect your fast drive so the app updates normally, or move the app back from the Moved tab. Apps that update very often, like browsers and chat apps, are usually happier on your built-in drive.
