Setapp is broken after I moved some folders

If you moved your user home folders to an external disk or another Mac (such as an M4 Mac Mini), Setapp may no longer open. This happens because macOS blocks Setapp due to changed permissions. To fix this, you need to restore Setapp’s permissions.

Example of home folders

Prerequisite: Make sure you are signed in to your Mac with an administrator account.

To restore permissions, follow these steps:

1. Open Finder and choose the volume that now contains your home folders.
2. Choose File > Get Info, or right-click it > Get Info.
3. Scroll down and expand Sharing & Permissions.
4. Click the lock  and enter your administrator password. It's required to make permission changes.
5. Clear the "Ignore ownership on this volume" checkbox.
6. Restart your Mac.

Now you can open Setapp and enjoy all its features.
