    I was reading through a mac magazine in a book store today and there was a mention of leaving your computer on until 3:15 am because that is what UNIX does for a self reboot or something like that. since old unix computers used to be on 24 hours a day.

    I am probably completely wrong and my memory is ill serving me, so I am curious about what it really is, what I should do, if I should do anything.

    On the chance what I am thinking is right and that since I am not usually up at 3:15 am, I could just change my clock at 3pm and then let it do what it needs to do.

    I have onyx, I am noticing a small decline in my system speed after a few months and want to try something.

    OSX does a little housekeeping in the wee hours, no reboots. If you sleep your Mac at that time, the housekeeping will be done when it awakes.

    really i was under the impression that you hade to keep it awake to run the scripes.

    but if i put my MBP to sleep at night, it will run the scrips when it wakes?
    any confirmation for this?

    I leave mine running at night, so that Time Machine and other maintenance tasks run when they're supposed to, and so that my daily Carbon Copy Cloner clone runs at 12:00 AM and NOT when my computer wakes up.

    That said, if you don't have an important scheduled task that needs to run overnight, I recommend sleeping the machine, for the simple reason that doing so saves power.
