iCloud progress not syncing

I love that this game supports iCloud syncing, but its not working on the Mac version so far. At startup, it prompts me to use GameCenter, which I already am logged in. And when I click the globe icon on the menu screen, then click Game Center, it just opens a blank dialogue box in the middle of the screen that can’t be closed, so I’m forced to quit the game from the dock.

Will score this a 5 star once iCloud syncing works properly!
