After Disabling Resolution Dialog on Mac, game won't launch

Hey, everyone.

I always made builds with Resolution Dialog (Settings screen when launching a unity game) enabled, and it worked fine. However, I was trying something new and I disabled the dialog, then made a build. When I try launching the game, the icon would appear on the dock and the game's title is written on the menu bar, but nothing is happening at all. it just stays that way. To make sure, I built the game with Resolution Dialog enabled again, and it worked with no problems. I'm using Unity 5.0.1f1 on a Mac running Yosemite 10.10.1

Thank you.
