If you have macOS 12.3 or later installed as the main operating system of your Mac, you may have issues opening Dropbox online-only files inside your virtual machine - the files might be shown as zero bytes in size.
Access online-only files from the virtual machine
Note: Online-only files have a cloud icon next to them.
- Open your Dropbox folder on the Mac side in Finder.
- Right-click the file you want to have available.
- Click Make available offline.
- The file will be downloaded within your Dropbox folder and can be opened from the virtual machine.
Once an online-only file has been downloaded in Dropbox, you’ll see the cloud icon change to a green checkmark.
