This could be a bit of a mess.
Following Apple’s seeding of the first beta for its macOS Monterey 12.3 operating system to the developer community for testing, in its released notes, the company confirmed that it has deprecated kernel extensions used by Dropbox and Microsoft OneDrive and notes that both cloud storage services have replacements for the functionality currently in beta.
Earlier this week, Dropbox announced that users who updated to the macOS Monterey 12.3 beta could temporarily encounter issues opening online-only files in some third-party apps on their Mac. Dropbox has yet to provide a reason for this issue, though it now seems to clearly related to the kernel extensions that enabled this functionality being deprecated by Apple.
Through a support document and email sent to customers, Dropbox said it is actively working on full support for online-only files on macOS 12.3 and will begin rolling out an updated version of its Mac app to beta testers in March. In the meantime, Dropbox users who update to macOS Monterey 12.3 will still be able to open online-only files in Finder.
Microsoft has also confirmed some issues between its OneDrive cloud system under the macOS Monterey 12.3 beta, and has stated the company is working on a new online-only files experience for OneDrive that is “more integrated with macOS” and “will have long-term support from Apple.”
Stay tuned for additional details as they become available.
