Hi Dearwolf,
Thank you for posting your query in our community.
Per your description, may I confirm that whether you encountered a problem that OneDrive used too much CPU on your Mac.
If yes, here are some suggestions for you, and I hope they can help you:
- You can click OneDrive icon>Settings>Preferences>Office to "Use office applications to sync Office files that I open" and uncheck it.
- Start or restart your Mac, then immediately press and hold the Shift key to let your Mac enter in safe mode to only open OneDrive and check if the issue persists without the inference of third-party software and font. For more information, please refer to the article: How to use a "clean startup" to determine whether background programs are interfering with Office for Mac (microsoft.com)
If the above 2 methods do not help, please reset the OneDrive app to check if there is any improvement.
- Quit OneDrive. (Select the cloud icon in the top tray, the select Settings > Quit OneDrive.)
- Find OneDrive in your Applications folder.
- Right-click OneDrive and select Show Package Contents.
- Browse to the Contents > Resources folder.
- Double-click ResetOneDriveApp.command (or ResetOneDriveAppStandalone.command, if you're using the standalone app).
- Start OneDrive and finish the setup process.
If the issue persists, I could appreciate it if you could provide me the following information and let us check them for you:
- You Mac OS version information;
- Did you make any change before the problem happen, such as: system update, Office update?
Best regards,
Jazlyn
