Today I buy minecraft for mac, and when I give the launcher and I play the game window opens, if you maximize doi or adjust the size of the game screen, I get all the blank screen and I get a warning that your computer has crashed and is rebooting.

I tried to do anything more fler on startup, or on the screen of a player, multiplayer options and the same thing happens.

I have updated java.

What I can do?

thanks

Also add something else:

I have a keyboard Spanish, and cuandoe stoy playing in chat I type the letters: ñ 'ç'

There is no way to write them, and other players can.

Em also happens in single player.

I have Spanish language in Spain and also prove to the English language, and there is no way to write them.
