    I read that repairing the Disk Permissions in Disk Utility every once in a while will increase the performance of my MacBook Pro. I did it, but I am not quite sure what it did to it. Anyone know? I'd like to know what it does if I keep on doing it.

    No, won't make any difference for system performance.
    This article, though about 6 years old, is still relevant.
