Hi @Pedro Nunez
Is there any error message during the process?
I suggest you try following steps to have a check:
- Make sure OneDrive is syncing properly before you attempt to move it to the external SSD.
- Click on the OneDrive icon in the menu bar.
- Go to Preferences > Account and click Unlink this Mac.
- After unlinking your account, restart OneDrive. It will prompt you to set up OneDrive again.
- During the setup, when it asks you for the location of your OneDrive folder, choose the Change location, select the desired location on your external APFS drive and follow the wizard steps to confirm it.
- OneDrive will now start syncing with the external SSD. Depending on the number of files, this might take some time.
- Ensure the SSD is connected and mounted when your Mac is on and when you want to sync your files.
