I think so. Run the actual binary in your terminal, and see what output is, there might be a clue there:<br><br>1. In Finder, go to Applications, Utilities, and run Terminal. <br>2. Type in "cd /Applications/OpenLP.app/Contents/MacOS" (without the quotes) and press Enter<br>3. Type in "./OpenLP" (without the quotes, but with the ./) and press Enter <br>4. You should see the icon bounce in the dock, and hopefully an error message in the Terminal. <br>
