LNuke

Please help me! A while ago i played Hack/Mine but now it doesn't work anymore. In all newer Versions the Game doesn't even start. When i click play, the Launcher hides for a moment and 3 seconds later it pops up again. In older Versions of Hack/Mine i just get a white screen. I've been waiting for 20 min. But still there was a whitescreen. I got a Macbook Air, 1.7 Intel Core I5, Intel HD graphics 3000 384mb. Running OS X 10.9 Hope you can help me with that Problem! ps: some other packs have the same problem. but some work. THANKS! Hope i can play this wonderful modpack in a while!! LNuke
