The developers of Findings are looking for people to test the latest features.
Findings Sync can already be enabled in the version 1.0.6 of Findings for Mac. First, make sure you have the latest version using the menu Findings > Check for Updates. After restarting the app, you can enable Dropbox sync in the 'Library' tab in your preferences (accessed via the menu Findings). Note that because of OS X security, you will need to give access to your Dropbox folder by selecting its location on disk (typically the Dropbox folder in your home folder). Do the same on all your Macs, and have all your experiments and protocols in Dropbox, available everywhere! Please let us know if you have any question or problem: send us an email using the Help menu in Findings
