"my cc" not working mac (apple blossom)

i just downloaded s4s in my mac trying to remove or fix some of my broken cc but for some reason every time i try to click on the "my cc" option it just exits me out of the application without doing anything ?? im very confused and i cant seem to find anything online to help me. 
with the unlikely chance of anyone actually seeing this plz help :') 
(all the other options seems to work "animation","build","cas" and "objects" just not "mycc")

thanks
