Ignoring visibillity rule and showing launcher due to game crash (mac)

When I try to log on to minecraft it closes out the minecraft screen, deletes minecraft and tells me my launcher crashed (p.s sorry if I made another post about this, I havent been on here for a while and I couldent find it.)

Some pictures of it. (p.s running on Imac, just recently updated to os x)

[ note in the second picture, the crafting table appears, and dissapears]
