10.9.2 causes slow shut down speed?

Question

Last week I bought a MacBook Pro retina and one of the many features that impressed me was its shut down speed. For the first 5 days I had been using it, the laptop shutdown in roughly 3 seconds,
However after I installed 10.9.2 update the shut down speed went up to 20-30 secs. This is with all foreground and background programs closed by the way.
I can pretty much confirm that the update is responsible because all I have done on the laptop so far is watch some YouTube and write some documents on pages.
Has this effected anyone else? Is this a known issue or do I have to accept the possibility that my macbook might deteriorate with each update?

Answer 1

Just something not too far away from these issues.
I have a 2008 Macbook (not recent I know but bear with me), the machine has 8gb ram and recently (past 6 months) 10.9.0 and an SSD
I noticed my shutown times were almost instant, longest possibly around 2 seconds after the install of the SSD so as you can imagine, I was delighted, most apps open almost instantly, the usual Safari, Firefox, even Xcode was quite snappy.
However, recently and by that I mean in the past couple of weeks, the shutdown times has increased to anywhere between 10 and 30 seconds, not new apps installed, not updated to 10.9.1 or 10.9.2
I guess, my point here is, could it be somehting that has been installed/updated without user concent, obviouly not 10.9.1/2 as I'm still showing 10.9.0 or perhaps just coincidental.
