Think twice about rushing to install macOS 12.3 if you use Dropbox or Microsoft OneDrive for cloud storage. Both services use kernel extensions that Apple is deprecating in its next Monterey update.
Dropbox and Microsoft are working on updates that will eliminate this problem. However, those are also in beta and could come with issues of their own.
macOS 12.3 breaks Dropbox and OneDrive
“The kernel extensions used by Dropbox Desktop Application and Microsoft OneDrive are no longer available,” Apple confirms in its macOS 12.3 release notes, which were published alongside the first developer beta last week.
Apple notes that “both service providers have replacements for this functionality currently in beta,” but those updates aren’t widely available yet. In other words, it’s best to avoid macOS 12.3 for now if you rely on these services.
Dropbox has also confirmed in documentation of its own that its current macOS app — which is still designed for Intel chips — does not work under macOS 12.3. Its next big update won’t just fix this, but it will also add Apple silicon support.
What to do if you’ve already updated
If you installed macOS 12.3 before finding out about this issue, you can download and install the Dropbox beta. Sadly, the OneDrive beta isn’t open to everyone; you need an invite and there are none currently available.
The other option is to simply access your cloud drives through a web browser. It’s certainly not the most ideal experience, but it may be good enough for now.
