Dear JEFF31572,
Welcome to the Microsoft Community.
I understand that you don't seem to be able to access OneDrive on your Mac computer.I understand that you are experiencing problems and will try to help you.
Based on the error message you describe, it appears to be caused by an incompatibility between the system version of macOS and the current OneDrive application.I note that you have not changed your operating system, but sometimes an application update or system update setting can cause this.
So, I'd like to know a little more with you to confirm the direction of the problem:
- Can I ask if you have updated your Mac system or OneDrive recently?
If it's convenient, I hope you can share with us the current version information of your Mac system (you can click on the Apple icon in the top left corner -> click on About This Machine) and the version of OneDrive (click on the OneDrive icon in the top left corner after opening OneDrive -> About OneDrive).
We will do progressive testing and troubleshooting based on the version information you provide.
- Have you changed the path of OneDrive in your computer recently?
- Have you tried some options to troubleshoot? For example,resetting OneDrive or reinstalling OneDriveto check if the problem is with OneDrive itself. I think this will give us further insight as to whether the problem is with OneDrive itself or with the system.
Additionally, in order not to interrupt your work, we suggest you try using the web version of OneDrive first:onedrive.live.com
I look forward to your further updates and hopefully we can follow up with you to get more information to troubleshoot the direction of the issue.
Thank you for your understanding and patience.
Best regards
