They are mad that they spent all this money on a mac and that is is performing like some super old PC with the blue screen of death. I know that no one expects this from a mac but it does happen, macs are not perfect, no computer is. The good thing is that there is a solution mac software can help you clean up your computer and regain the speed that you have lost. This is much better than trying to update or replace your computer.
