Why does my MacBook Pro (with OS X 10.8.2) startup slow and is slow to shutdown?

    I have also experienced this with my 2012 SSD MBP.  Shutdown and startup to and from useable has increased from less than 10 seconds to more than 30 seconds.  Quite annoying, and not why I forked out over 800 smackers for the SSD and 2.7 GHz.  Seems interesting - Apple improves features that I don't care about (Facebook integration, etc), then makes changes to battery life *supposedly*, haven't verified it - but my battery life seems as terrible as ever since upgrading to Mountain Lion -  then screws up the best feature of 10.8.1 - the incredibly fast shutdown and startup.  I timed it at 6 SECONDS before the upgrade.

    Try these:

     

    system preferences - startup drive - select your drive as the start up drive then restart.  if that doesn't do it for you, then go to disk utility and verify your disk permissions - if errors are found - repair them then restart your macbook once the repair is done.

    Done!  No change, but thanks Bimmer.  Chrome crashes a lot too, FWIW.

    Nearly the same for me - startup didn't change, but the shutdown time went up from 2 seconds to nearly up to 20 seconds - even with all applications closed beforehand...

    Bimmer, after ultraspiralce and Mr. Germany's experience, I will hold off on trying that approach.  Thx for your time though.  I may go make a G-Bar appt and get some help or get my curiosity satisifed. -GFS.

    GFJS - please update us on your findings here.

     

    There's another thread on MacRumors - nothing is coming of it yet, but we might monitor it also -

    I do have to say that the OS is perfectly useable, other than the occasional Chrome hiccups and slow shutdown - I can't really find anything else wrong with it.

     

    Many thanks!

    Alcon, I will update you after my visit to the Apple Store.  I agree that "OS is perfectly useable and a slow start-up and shutdown is relative compared to my old PCs!  -GFS.

    Agree with you, i can´t understand what is going on with the latest software not only Lion, also iOS6, it´s a shame now it looks like apple have terrible issues with the upgrades. Amazing my Pc looks faster than my MBP.

    I had the same problem but this fixed it for me:

     

    1. Shut down your computer with "Reopen windows when logging..." CHECKED. (The shut down might be slow this time ~ 20 seconds).

    The default setting for mine was unchecked. If yours was checked by default, try UNCHECKING it at this point.

     

    2. Turn your computer on

    3. Every time you turn your computer off, it should shut down in about 2 seconds. (It does for me)

     

    Good Luck!

    Thanks for the suggestion.  It didn't take care of my shutdown issue, and I wonder why it fixes some and not others.

     

    I'm also going to lean toward taking back my earlier statement that 10.8.2 was "completely useable" and change it to "10.8.2 might just be a piece of crap"- while I was performing the above steps, I restarted and there was no menu bar visible afterwards.  After I clicked around for about 20 seconds, the menu bar finally popped up.  It's not the first time I've observed this happening, and it NEVER occurred before 10.8.2.

     

    Shutdown time is more than 30 seconds, which is greased lightning compared to my 2006 Vista PC, but unacceptable for this machine....

    Hahahaha, absolutely 10.8.2 piece of crap, now My problem is solved i just get back to 10.7.4, i realy hope Apple fix the problem. Sad but thru "we need Steve J. Here"

    I agree - so strange.  Lion 10.7.4 was SO STABLE and ran everything perfectly for my machine.  I can only hope that 10.8.4 will be the same, but I can't wait too long for it.  Otherwise, I'll have to go back.

     

    Cheers guys - I'll check in if I find out anything and please keep us all updated.

    hm... that's weird.

    Someone at MacRumors suggested to clean the system cache and it seemed to have fixed this issue for him:

     

    sudo chown root:admin / (enter password when asked)


    sudo kextcache -system-prelinked-kernel


    sudo kextcache -system-caches
