Why does an app show no last-used date?
Short answer: macOS has no recorded open date for that app — often because it has never been opened on this Mac or was recently reinstalled. It doesn't affect whether the app can be moved.
macOS hasn't recorded an open date for it. That usually means the app has never been opened from Finder, the Dock or Launchpad on this Mac, or the system's record of it was reset — for example after it was reinstalled.
It doesn't affect whether the app can be moved. Check the app's size and safety badge, and remember that a missing date doesn't prove you never use it.
