A Microsoft file hosting and synchronization service.
Hi Rob,
Regarding your concern, this is most likely a macOS compatibility issue, rather than a problem with your Microsoft 365 business account. Microsoft’s current OneDrive system requirements specify macOS 14.4 or later. Since your Mac is running macOS Ventura 13.7.8, it's expected behavior that a newly installed current version of OneDrive can be installed but then fail to open.
In this case, I suggest you consider upgrading your macOS to macOS Sonoma 14.4 or later via Apple menu > System Settings > General > Software Update, then download and reinstall OneDrive from Microsoft’s official download page.
If your Mac cannot be upgraded, the only supported option is to access your business OneDrive through OneDrive on the web.
