So I've been having a problem with my minecraft. All versions lower than 1.5.2 won't work. Every time I try to launch 1.5.2 (or lower) all I get is A Mojang logo that just stays there. I do not have any cheats, mods, or anything like that, pure vanilla. I use a MacBook Pro . Here is the crash log

Someone is closing me!

Please help me anyone,

Does this folder actually exist?

I have the same problem .-.

Yes, It does exist. I am on mac that is why

Also I wanted to say that sometimes, instead of the Mojang logo, there is a black screen or glitched screen
