Long Shutdown Time of MacBook Pro (10.5.8)

[Tomlija]

Hi guys!

I am having issues with the shutdown time of my MBP. Namely, until couple of days ago, everything was fine and the shutdown process lasted for about 5 seconds tops. The other day, when I was about to go to bed and shut it down, the shutdown took unusually long time to execute. From that day on, every shutdown is the same. It lasts for about 40 seconds. This is kinda not that funny, because from time to time, like every couple of months the shutdown would be long like this, but the next shutdown would be very short. I consider this to be normal, as far as I read the various forum posts. What bothers me is that since couple of days ago, every shutdown lasts for about 45 seconds and it is not a problem, since the computer works fine, but is kinda irritating. I also have to mention that no major changes (installation or removal of programs) have been performed prior to this issue, and that my login items list is empty.
I have tried the following:

* Zapping the PRAM
* Executing various Onyx scripts, and used Onyx it to clean various caches.
* Reading, verifying and repairing permission using Disk Utility.


None worked for me.

I am pretty sure there are numerous threads about this or similar subject, but I have not found the one that describes this issue that I have.

If anyone of you, guys had the similar problem, any help, advice or tip would be greatly appreciated.

Sincerely,
Matt

Has any new software been installed that my be causing issues when shutting down? You could check the Activity Monitor and see if there are some out of the ordinary processes that aren't shutting down. Are you having any issues with performance while the machine is still on?

Thanks for the reply!

No, no new programs have been installed since, and otherwise, computer works just fine. Are you saying that I should turn on the Activity Monitor and then, with Activity Monitor open, shut down the computer and see what is going on with all the processes?

Dear CANEHDN,

I boot my OS from the installation DVD and did Disk Repair from the Disk Utility as well. It said that my start-up volume appears to be OK. Later, I used Macintosh HD to boot the OS, and when I restarted it, it still took a very long time for the computer to shut down. I really don't know what else to do.
Maybe it has to do something with me installing Security Update 2010-002, Quick Time Player, and iTunes update a couple of days ago, but I doubt it.

Any ideas, please?

Cheers.
Matt
