I’m successfully syncing two Macs via Dropbox. The setup procedure is as follows:
On the origin computer:
Make sure the Dropbox software is installed and configured with your account.
Open the database you want to sync.
DevonThinkPro -> Preferences -> Sync tab. All your open databases will appear in the first pane. Select the one you want to sync.
In the second pane, set the synchronization times.
In the third pane, set the sync destination. This will be your Dropbox account. Double check the sync times after you do this, as the settings sometimes don’t seem to “take.”
(The first time you do this, Dropbox will ask if DTP is allowed to use your account. Say yes, obviously.)
Click the button to “Sync Now,” and wait for it to finish.
On the destination computer:
Make sure the Dropbox software is installed and configured to access the same account.
Go to the Sync tab and click Import Database. DTP will offer you first the chance to select your Dropbox account, then ask which database you want. The selected database will then appear in pane 1.
Proceed as above.
The first sync will take some time because DTP has to upload, then download, a complete copy of the database. After that, it will only need to copy the things that have changed.
From here on out, the sync should be pretty seamless. Always make sure that it’s completed before you shut down the computer you’re using.
