    This is my first post here and I really appreciate if anyone can give me some insight to my problem.

    I have a MBP late 2007 model which I updated with 10.5.7 and SMC 1.3 about 3 days ago.

    I then experience the following problems:

    1. Can't shutdown/restart
    2. Very sluggish performance after 45 minutes or so
    3. Also after around 45 minutes internet connection would drop to a zero. (I am using Netgear WRT954T router updated with latest firmware)
    4. Hard restart required every time

    I notice there are other people here also experiencing some form of reduced performance issues but all the solutions offered (like resetting SMC, using OnyX etc) don't have much use.

    Do I need to wait until Snow Leopard to solve this problem?

    Thanks for reading.

    For the 10.5.7 update did you use Software Update or did you download and install the Combo update? Either way try installing the Combo update (again) and see if this helps any of your issues.

    I updated when flagged by my Mac so I suppose that's 'software upgrade'. I will try and find 10.5.7 combo upgrade.

    Just like to report the followings:

    I have reinstalled the update using the combo download and no dice.

    I tried to disable spotlight, no dice.

    But I do notice, using Activity Monitor, that my Macbook Pro's CPU turns to full blast (system usage 95%+) approximately one hour after I turn on/restart the computer. No new and noticable programs hogging the system and the thread counts shoot to over 400.

    I am glad to report that I have solved my problem by uninstalling 'Network Magic'.:D:D:D
