This is a rather vague post but basically are there any applications or tests (either 3rd party or native) that can test if my mac is running smoothly? I have not been impressed or noticed any difference since the switch to 10.6 and I have even had issues with crashes, shutting down, and speed. Thanks for your help.

Macbook Pro, Mac OS X (10.6.2), 2.5 GHz, 4 GB RAM, 250 GB Hard Drive

    HI Tyler,

    Several things come to mind...

    Boot from your install disc and run Disk Utility. If it finds errors on the startup disk, Disk Utility can repair them.

    Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    *(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
    Select your start up disk and click Restart

    While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*

    You can also boot from your install disc and run the Apple Hardware Test, instructions Here.

    Go here for hlep to
    Maintain Mac OS X

    The most important thing you can do is back up your important data in case you should have to reformat the drive.

    The X-Lab document Carolyn referred you to is an excellent read, overall, but there are a couple things to comment on. First, the Unix maintenance scripts run overnight, and although they'll never run if you shut your machine down overnight every night, this is not true if your machine sleeps overnight. In that case, the scripts that were supposed to run will run as soon as your machine wakes up.

    Secondly, I would disregard their recommendations to keep on top of virus definitions and scans... don't bother with anti-virus software at all. Most Mac AV software is known to cause more problems than it solves (especially since it can't actually solve any problem at this point in time).

    It would be best to identify some specific issues and ask about them. You will probably be asked about the contents of your log files via Console.app and what applications you have installed and how you installed them - i.e. did you install them in 10.6 or did you upgrade 10.5.

    You said "since the switch to 10.6..." How exactly did you make the switch? I've never been a fan of the 'upgrade' instead preferring a 'clean install.' If you didn't (and can) I'd suggesting a big backup, a wipe of your system media, and a nice clean install of Snow Leopard. Follow it up with a Combo Update.

    That said, someone already made the suggestion of running Disk Utility tests. You could also look to a third party application like TechToolPro or Disk Warrior (which can report on different Mac 'health' issues.)

    The Upgrade path in Snow Leopard is very good. An Uprgrade install has gotten a bad rap altogether, but I think a SL upgrade is the way to go unless you are moving from a system that has problems already.

    I have to agree with Barney, there's absolutely no reason for this level of paranoia. I upgraded Leopard to Snow Leopard and my system works perfectly. The only reason to do a "clean install" is if your system is having problems and that's the easiest way to fix them.
