Hello Mojang! I have figured out a crash that has occurred on only my Mac, and not on my brothers'. I don't know why, but when I run the Minecraft Launcher with WIFI on, it loads for about 0.5 secs and then stops and closes. I have no idea why, but this bug is also preventing my Minecraft Launcher from updating, making it so that I can not run the latest snapshots to try them out. This has affected my Mac OSX. There are no screenshots below because I can't take one, since the Minecraft Launcher isn't loading in the first place. This bug has been affecting my Minecraft for the last month and it really is bugging me and stopping me from playing Minecraft easily.
