How to Fix Microsoft OneDrive Not Syncing on Mac in macOS 14 Sonoma

Microsoft OneDrive allows users to store files in the cloud and synchronize them across multiple devices. On macOS, OneDrive automatically syncs files between your Mac and your cloud storage so that any changes are updated across devices. However, some users running macOS 14 Sonoma may experience issues where OneDrive stops syncing, shows syncing errors, or fails to upload or download files.

This issue can occur due to outdated OneDrive versions, network connectivity problems, incorrect account settings, or macOS permission conflicts. In some cases, a corrupted sync cache or temporary system glitch may also prevent files from syncing properly.

If Microsoft OneDrive is not syncing on macOS 14 Sonoma, try the troubleshooting methods below.
