Dropbox support for macOS 12.3

Users on macOS 12.2 may see a compatibility warning about the Dropbox system extension. Dropbox will still work as expected and you can dismiss this warning by clicking OK.

Dropbox is actively working on full support for macOS 12.3 (Monterey) and higher. A private beta version is currently available to select users. If you’re interested in joining, you can turn on early releases to be notified when you’re eligible.

If you choose to update to macOS 12.3, you may have issues opening online-only files in third-party applications on your Mac. As a temporary workaround, you can open online-only files directly in Finder.

​​Note: On macOS 12.3, online-only files will show as zero bytes in size.

How to open files when they’re online-only

Note: Online-only files have a cloud icon next to them.

To open online-only files:

  1. Open your Dropbox folder in Finder.
  2. Double-click the file you’d like to open.
  3. The file will be downloaded within your Dropbox folder and will open in a new window.

To make an online-only file available to open in third-party applications:

  1. Open your Dropbox folder in Finder.
  2. Right-click the file you want to have available.
  3. Click Make available offline.
  4. The file will be downloaded within your Dropbox folder and can be opened through any third-party application.

Once an online-only file has been downloaded in Dropbox, you’ll see the cloud icon change to a green checkmark.
