People running OneDrive versions older than 22.0103 would also face issues running Files-on-Demand, a function used to open files within Apple's File Provider platform, Microsoft said. "Both service providers have replacements for this functionality currently in beta."

"The kernel extensions used by Dropbox Desktop Application and Microsoft OneDrive are no longer available," Apple said in a blog detailing the new build last week. It explains that Microsoft will be using Apple's File Provider extensions for future OneDrive versions, that the new Files On-Demand feature will be on by default, and that Files On-Demand will be supported in macOS 12.1 and later.Apple removed kernel extensions in the beta version of macOS 12.3, causing testers running OneDrive to see the prompt "OneDrive couldn't start." Testers using Dropbox had trouble opening online-only files due to the same problem. Microsoft's documentation for OneDrive's Files On-Demand feature is more detailed. The page notifies users that Dropbox's online-only file functionality will break in macOS 12.3 and that a beta version of the Dropbox client with a fix will be released in March. Apple says that "both service providers have replacements for this functionality currently in beta."īoth Microsoft and Dropbox started alerting users to this change before the macOS beta even dropped. The extension means that files are available when you need them but don't take up space on your disk when you don't. If you're using either Dropbox or Microsoft OneDrive to sync files on a Mac, you'll want to pay attention to the release notes for today's macOS 12.3 beta: the update is deprecating a kernel extension used by both apps to download files on demand.
