Unsure how to open client (Mac)

I have been having difficulty opening the game ever since the new Riot Launcher.

1. I click League of Legends and nothing happens...
2. I click Riot Launcher and it tells me "The game cannot be opened this way please launch directly"
3. I click League of Legends icon again it launches the Riot Launcher successfully

This is how I have been signing in since the new launcher was released.

Am I missing something?
