A Microsoft file hosting and synchronization service.
Thank you for sharing your concern.
Based on your description, this behavior appears to be related to how the OneDrive UI components are interacting with your macOS device. Although both FileProvider and FinderIntegration are enabled and OneDrive processes are running, the absence of icons in both the menu bar and Finder suggests that the UI layer (menu bar application and Finder extension) is not properly registering or attaching to the current macOS user session.
To troubleshoot this issue, you can try the following approaches:
Check for menu bar overcrowding
MacOS may silently hide icons when there isn’t enough space, and apps that load later (like OneDrive) are often the first to be clipped.
You can try temporarily quitting a few other menu bar apps or disabling some items under System Settings > Control Center. If the OneDrive icon appears, then it was likely hidden due to layout constraints.
Restart the UI component cleanly
Even if the sync engine is running, the UI process responsible for displaying the icon can become unresponsive.
Open Terminal and run:
killall OneDrive
Then relaunch OneDrive from the Applications folder.
Alternatively, you can use Activity Monitor to quit all OneDrive-related processes (including Finder integration extensions, if present), and then start the app again.
Clear the local UI/container state
A corrupted container can prevent the app from registering its interface properly, even when the toggles appear enabled. You could try to: Quit OneDrive completely (ensure no processes remain).
In Finder, press Cmd + Shift + G and go to: ~/Library/Containers
Locate any folders related to OneDrive (such as com.microsoft.OneDrive-mac) and either temporarily move or rename them.
After that, reopen OneDrive and sign in again. Then check the menu bar to see if the OneDrive icon appears.
