# App safety levels

Every app on the Internal tab gets one of four safety badges, Safe, Caveat, Override or Blocked, which decide whether it can be moved and whether you must confirm a known risk first.

Before Storage Studio offers to move an app, it checks how the app is installed, how it updates and what else on your Mac depends on its location. The result is one of four badges on the **Internal** tab of the [Apps window](https://storagestudio.us/wiki/the-apps-window): **Safe**, **Caveat**, **Override** or **Blocked**. The badge decides whether the **Move** button appears.

## The four badges

| Badge | What it means | Moving |
| --- | --- | --- |
| **Safe** (green) | No known issues with moving this app | **Move** starts straight away |
| **Caveat** (orange) | Safe to move, with a small side effect worth knowing | **Move** starts straight away |
| **Override** (red) | There's a known risk | **Override → Move** asks you to confirm the specific risk first |
| **Blocked** (grey) | Can't be moved safely | No **Move** button |

The line under each app's name says why it got its badge, and hovering over the badge shows the same reason. The **?** button at the top of the window has a guide to every badge and label.

## What leads to each badge

**Blocked** — Storage Studio won't move:

- Storage Studio itself.
- Apps built into macOS.
- An app you've already moved. Use the **Moved** tab to bring it back.
- Apps signed by Apple, because macOS or the App Store may update them where they were installed.
- An app that is open right now. Quit it, click **Refresh**, and the badge is worked out again.
- Apps managed by Setapp, which re-downloads apps it thinks are missing.

**Override** — you can move it, but only after confirming:

- The app was installed by macOS or an installer as a protected, system-owned app. Moving it needs your administrator password.
- The app's updater is known to reinstall apps where they used to be, or Storage Studio can't tell how its updater behaves.
- The app's own files point to its original location, so parts of it may look in the wrong place after a move.
- The app uses a helper tool or a background item registered at its original location.

**Caveat** — it moves normally, but:

- macOS may ask again for permissions such as the camera or microphone the first time you open it after the move. Click **Allow**.
- It's in your Dock, so its icon may briefly show a placeholder after the move.
- You used it in the last few days.
- It updates itself, or was installed in a way that Storage Studio watches so it can redo the move after an update.

**Safe** — none of the above applies.

## What the badge doesn't decide

- **Offload** and **Uninstall** are offered for every app, whatever its badge. They work differently from a move: see [Offloading and restoring an app](https://storagestudio.us/wiki/offloading-an-app) and [Uninstalling an app completely](https://storagestudio.us/wiki/uninstalling-an-app).
- A badge is worked out again every time the window scans your apps, so it follows the app's current state.
- When a move starts, Storage Studio checks again that the app is still there, isn't already moved and that your drive is ready. If something changed, the move stops and the reason appears at the bottom of the window.

Sort the list by **Safety** to see all the apps you can move freely together.
