The latest Mac v2.0 patch has a bug for new users of the app, and does not affect users who upgraded — it will continually pop up the help message box. We have patch 2.0.1 already submitted to Apple, but for the technically savvy who want to fix it immediately:

1) Shutdown the app and open up ~/Library/Preferences/com.deckedbuilder.deckedbuilder.plist in your favorite text editor

2) Add the following XML lines at the end of the file before the final </dict>:
    <key>help.firstCollection</key>
    <true/>
    <key>help.firstCollection2</key>
    <true/>
    <key>help.firstDeck</key>
    <true/>
</dict>

3) Restart the app

A special thanks to Miguel Iglésias Marques and Dan Ignat for reporting the bug and helping to test the fix.

We do apologize for the inconvenience!
