Anything to Record Gameplay and Skype for Mac?

So my friends and I wanted to start recording our games and Skype calls for fun and to post on one of our youtube channels. So i though I would make my own and stuff. The only problem is that I have a mac and most recording products that record Skype and league audio and video are for windows. Are there any programs (preferably free) for Mac that I can download that will record my league games with audio from both the game and Skype call? Also sorry if this is the wrong section to put this lol
