Kazuki713 started following [1.6.2] Half-Launching Installer on Mac 10.6.8 (fails to launch)
I'm having the same issue as well, just a blank window with a few buttons that don't work. I'm trying to install build 871 for 1.6.2, and it seems to have the same problem with all of the versions I've tried except build 789. For some reason that one works fine. Unfortunately, I'm trying to set up my Minecraft for a modded server which is using 871, so installing 789 won't do me much good. For what it's worth, I'm also using Mac OS 10.6.8 and I have the latest version of Java available to me.
