Bonus Tip: How to Fix OneDrive Error Code 43 on MacBook

Mac users may encounter error code 43 when using OneDrive, which can be caused by issues with the OneDrive app, corrupted files, or permissions problems. To resolve this issue, users can try restarting the OneDrive app, checking the file's permissions, and verifying the file's integrity. If the problem persists, users may need to reinstall the OneDrive app or seek further assistance from Microsoft support.

To resolve OneDrive Error Code 43 issues on a MacBook, users can try restarting their computer, updating OneDrive, checking for corrupted files, and resetting OneDrive. They can also try deleting the OneDrive cache and settings, reinstalling OneDrive, and checking for any conflicts with other cloud storage services.

Method 1. Fix Error Code 43 by Checking Your Applications Folder

Step 1. Navigate to the Applications folder on your computer and check to see if there are any other OneDrive installations present.

Step 2. Delete the duplicates and preserve one app version.

Note: Updating or reinstalling an app on a Mac can lead to multiple copies of the program being created, causing the operating system to become uncertain about which version to use.

Method 2. Use OneDrive in Safari, Chrome, or Edge

If the problem still exists, try these things:

Step 1. Log out of your desktop app and shut OneDrive.

Step 2. You can't access OneDrive Live in a new tab. OneDrive Live is a feature that allows you to access your OneDrive files from the browser, but it's not a standalone website that can be accessed in a new tab.

Step 3. Verify that error 43 still appears, as it's unacceptable for OneDrive Online to have the same bugs as the desktop client. To resolve the persistent issue, try switching to a different web browser, such as Safari, Chrome, or Microsoft Edge.

Method 3. Check the File Name to fix OneDrive Error Code 43

OneDrive may not discover files with brackets, signs, or apostrophes. To resolve this issue, you need to replace troublesome characters in file names and paths.

Note: OneDrive may not support certain characters that a Mac supports, and it can get confused by file names that have spaces at the end, unlike a MacBook which handles them normally.

To resolve Error 43, reset OneDrive settings and start a new sync from scratch, which won't result in data loss.

Step 1. Turn off OneDrive entirely.

Step 2. Afterward, open OneDrive by going to the Applications folder.

Step 3. Select the option to View Contained Files from the app's context menu.

Step 4. Select the Resources subfolder from Contents.

Step 5. To reset OneDrive, double-click on the "ResetOneDriveApp" command, while OneDrive standalone users should run the "ResetOneDriveAppStandalone" command instead.

Step 6: Restart OneDrive and see if anything has changed.
