Recently I updated to mac OS X Yosemite on the beta. Whenever I try to launch a mod pack they give me white screens. Is this a known problem with OS X Yosemite or with my computer. I knew that some applications would not work with the upgrade, but I was just wondering what could be causing this. It never crashes, and whenever I redownload the packs it never works. Also wanted to tell everyone about this problem incase it was not just my computer. If this is a known problem for OS X Yosemite, when will an official OS X Yosemite build come out?
