In the last week and a half, I have noticed that my 27" iMac (which used to shut down between 3-5 seconds) is now taking 10 or more to shut down. I haven't installed any major apps lately, nor have I really "changed" anything, which is why I'm wondering if anyone else has experienced this too?

I "have" gotten a few updates in the last few weeks or so from Apple for the Mac, but I don't know if that has anything to do with the price of tea or china.

Anyone else have this problem, and/or know what it might be? (something in the processes that has changed, or taking up resources?)

As a side note, the iMac itself still performs very fast, and I don't notice ANY change in the performance of it - which is a GOOD thing! It's still lightening fast, it's just the shut down that's bugging me lately as it's slowed down.
