hey i just downloaded technic launcher today and i can play all the mods fine, except i get random black screens. I play crazy craft for example (the only reason i downloaded technic) and maybe 15-20 minutes after playing my screen goes black. It stays black, unless I switch desktops (im on mac osx) and after switching back to the desktop which minecraft is on it fixes itself for 5 seconds then goes black again. I have to keep restarting lots, and it's really annoying. I've tried other modpacks, crafting dead, other versions of Crazy craft and it still happens. Any help is appreciated

im running on mac osx yosemite 10.10.2
mac air mid 2013 11"
1.3 GHz Intel Core i5
4 GB 1600 MHz DDR3
Intel HD Graphics 5000 1536 MB

I tried to download voidswrath launcher before downloading technic, doesn't even open with latest java on my mac.

thanks a lot guys

also in launcher options for technic ive got memory usage set as 2gb, should i add 4gb since i have 4gb ram?
