How to Fix OneDrive Open at Login Not Working on Mac

Product: Microsoft OneDrive
Device & OS: macOS
Scenario: Setting up automatic cloud synchronization when the Mac boots up or a user logs in.
Observed behavior: The "Open at login" option repeatedly becomes unchecked on its own after several days, preventing OneDrive from launching automatically.

Before you start

Ensure you are logged into your Mac with an administrator account, as modifying system startup items may require elevated privileges.

Solution 1Recommended

Add and Enable OneDrive in macOS Login Items

Manually adding the application to your Mac's official Login Items forces macOS to recognize and launch it upon startup.

Sometimes application-specific startup settings fail to communicate with macOS. Adding the app directly through Mac System Settings ensures the operating system handles the startup process.

Open System Settings

Click the Apple menu located in the top-left corner of your screen, then select 'System Settings' (or 'System Preferences' on older macOS versions).

Navigate to Login Items

Click on 'General' in the left sidebar, then select 'Login Items' on the right.

Add OneDrive

Look for OneDrive under 'Open at Login'. If it is not listed, click the '+' button, navigate to your Applications folder, select OneDrive, and click 'Open'. Ensure that the toggle next to it is turned on.

Add and Enable OneDrive in macOS Login Items

System-Level Priority: Adding the app directly to macOS settings overrides temporary app-level glitches.

Solution 2

Enable the Startup Option in OneDrive Preferences

Check the built-in application settings to ensure the startup flag hasn't been accidentally disabled.

Solution 3

Reset the OneDrive Application

If the setting continues to revert automatically after a few days, the app's configuration files might be corrupted and need a reset.

Frequently Asked Questions

Why does my Mac keep removing OneDrive from login items?

This can happen due to minor macOS permission glitches, conflicts with third-party optimization software, or a corrupted OneDrive preference file. Resetting the OneDrive app usually resolves the underlying configuration conflict.

How do I manually start OneDrive if it fails to open at login?

You can manually launch the application by opening Finder, navigating to your Applications folder, and double-clicking the OneDrive icon. It will then appear in your top menu bar.

Will resetting OneDrive delete my locally synced files?

No, resetting the OneDrive application will not delete any of your actual files or folders. It simply resets the application's configuration preferences and initiates a fresh sync check to ensure your files are up to date.
