Fix OneDrive Sync Problems on Mac Mini M4 (macOS Sequoia)
Question details
The user is experiencing persistent OneDrive synchronization issues where the application repeatedly requests a restart when trying to sync to an external APFS location.
- Product
- OneDrive
- Device & OS
- Mac mini M4 running macOS Sequoia
- Scenario
- Syncing files to an external APFS drive using OneDrive on a new macOS installation.
- Observed behavior
- OneDrive repeatedly reports that it needs to restart before it can sync the external location, creating a loop that standard troubleshooting steps cannot resolve.
Ensure your macOS Sequoia is updated to the latest version and verify that the external APFS drive is securely connected, properly mounted, and has read/write permissions enabled.
Perform a Clean Reinstall of OneDrive using App Cleaner
Completely removing OneDrive and its hidden residual files before reinstalling from the Mac App Store resolves persistent sync loops and external drive compatibility issues on macOS Sequoia.
Standard uninstallation methods, such as dragging the OneDrive application to the Trash, often leave behind corrupted cache and preference files. These remnants can cause the app to remain stuck in a restart loop when attempting to sync with an external APFS location.
Using a dedicated uninstaller tool ensures all configuration files are cleared, allowing for a fresh setup.
Download and open a dedicated Mac application uninstaller, such as App Cleaner. Locate Microsoft OneDrive in the applications list and select it for complete removal, ensuring all associated cache, containers, and preference files are checked.
Click 'Remove' or 'Delete' in the utility to completely uninstall OneDrive, then empty your Mac's Trash to ensure no files remain.
Open the Mac App Store, search for 'Microsoft OneDrive', and click the download icon to install a fresh copy of the application.
Launch OneDrive, sign in to your Microsoft account, and during the initial setup, choose your external APFS location for the sync folder.

If you are tired of troubleshooting complex OneDrive sync errors and external drive permissions on your Mac, consider switching to WPS Office.

Frequently Asked Questions
Why does OneDrive keep asking to restart on Mac?
This restart loop typically happens due to corrupted application cache data or conflicts with macOS permissions, particularly when attempting to sync files to external drives formatted as APFS on newer macOS versions.
Can I sync OneDrive to an external drive on macOS Sequoia?
Yes, you can sync OneDrive to an external drive, but Apple requires the drive to be formatted as APFS. If you encounter setup errors, performing a clean reinstall of the app often resolves underlying compatibility issues.
Is simply dragging OneDrive to the Trash enough to uninstall it?
No, dragging the application to the Trash leaves behind hidden preference files, application support containers, and sync configurations. Using a dedicated removal tool ensures a clean slate, which is essential for fixing sync problems.
Will uninstalling OneDrive delete my cloud files?
No, uninstalling the local OneDrive application does not delete your files stored in the cloud. It only removes the local sync application and settings, which you will reconfigure upon reinstallation.
