MacBook won't turn off
i have a problem for over the year now. My MacBook won't turn off. It stops on this screen https://www.dropbox.com/s/qtwx936284ar0p...
It was on Lion and after updating to ML. I can't do system updates because of this.
I was trying resetting SMC, NVRAM, PRAM.
I wan't doing a format of HDD, because I'm worried about bringing the problem again.
Maybe You can help.
Sorry for my english. I hope You understand it.
Is this a good question?
