Mac Helper Tool Not Installing What

Alright, so I try to launch Origin for the first time ever, already bought Spore so was going to go install it, and either this engine is just glitching or EA doesn't know how to do anything... Anyway. I got a screen which said...

"In order to manage your games, Origin needs to install a helper tool. Type an administrator's name and password to allow Origin.app to make changes."

It continuously asks this after I log in, so how do I play the game I paid for...?
