Troubleshooting & messages · Moving, offloading and restoring apps
What happens if I cancel the password prompt when moving an app installed by macOS?
Short answer: System-owned apps need your administrator password to move. Cancelling stops Storage Studio before anything changes — the app stays put and works as before.
Apps installed by an installer package (rather than dragged to Applications) are owned by the system, so moving them needs your administrator password. If you cancel that prompt, Storage Studio stops before touching anything — the app stays exactly where it was and keeps working.
To move it, try again and enter your password. If it's a Mac App Store app, App Store updates may not follow it to your drive, which is why Storage Studio lets you decide.
