Dear Sarah Machacek,
Greetings! Thank you for posting in Microsoft Community.
I'm sorry to hear that you're experiencing issues with OneDrive on your Mac. I'd like to help you, please let us cooperate, we can work together to narrow down and resolve the situation.
Firstly, for those folders and documents that haven't synced to OneDrive Cloud, I recommend you back up them to a different folder on your Mac. This helps to avoid losing data.
Then you may try following steps:
1.Restart OneDrive: Sometimes, restarting OneDrive can help resolve syncing issues. To do this, click on the OneDrive icon in the menu bar and select "Quit OneDrive." Wait a few seconds and then open OneDrive again. Put a document into OneDrive folder and see if it will upload to OneDrive Cloud.
2.If it still doesn't sync files, try unlink and re-link OneDrive. For detailed steps, please check Unlink and re-link OneDrive
- Reset OneDrive: If none of the above steps work, you can try resetting OneDrive. To do this, please follow steps in this support article Reset OneDrive
If none of these steps work, I understand how frustrating this situation can be and sincerely apologize for the inconvenience caused. Let me help you further. I would appreciate if you could share following information:
1.May I know the version of your OneDrive application?
2.Is there any error message when it doesn't sync files to OneDrive Cloud? You may check the OneDrive icon in notification area. If yes, could you please share a screenshot of the error?
3.May I know if it worked before? If yes, when did this issue start happening?
Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution.
Thanks for your cooperation and understanding. I hope that you are keeping safe and well!
Sincerely,
