    Which part of the shut down process is taking 10-15 seconds? Getting to the gray screen or when you're on the gray screen with the spinning wheel indicator?

     

    What was running prior to you shutting down? What is open when you shut down? What if you do a clean boot and then immediately shut down, is it just as slow? What startup processes do you have?

    I am getting a grey screen for 3-4 secs and later a spinning wheel until it shutsdown. I keep no running processess at the time of shutdown

    Yeah , clean boot and immediately shutdown is same as before. I have two startup processess of which either of them are not ticked.

     

     

    Please help me.

     

    Thanks in advance.

    Your signature and post don't mention which version of the OS you are using. If you updated to 10.8.2 that might be the reason for the shutdown delay. Many people are reporting signficcant shutdown delays after that update.

    I bought Macbook Air 2012 Mid (Ivybridge release-present on website rightnow)

    It came with free Mountain lion upgrade , So i updated.

    So is there anyway to repair that problem ??

    Thanks in advance.

    There are multiple ways to "fix" it:

     

    1.) Take a deep breath, count to 10 and it'll be shut down.

    2.) If it came with Lion you can downgrade back to 10.7.x

    3.) Don't shut down the machine if you're unable to wait the 10-15 seconds, the machine has an SSD the wake from sleep is faster than starting it up anyway.

     

    Truthfully, I don't think there is a fix. Every machine I've dealt with running 10.8.2 or 10.8.3 all experience a delay in shutting down. Just think what it'd be like if the machine didn't have an SSD! My 15" MacBook Pro takes a solid minute if I had a lot of stuff running.

     

    Sorry there's no better answer, if you hear one from Apple, feel free to relay it here.

    Jason - if you have access to a computer running 10.8.3 you can't talk about it since it is in developer beta  (I think)

     

    The 10.8.2 update brought longer shutdowns - honestly until someone mentioned it I never noticed - that's how often I shut down my computer

     

    If this is a bug I'd expect the 10.8.3 update will fix it but it may be that Apple found an issue that requires a longer shutdown - perhaps there are some new cache evaluations or something. At the moment the only 'fixes' I know of are reverting to 10.8.1 (assuming you have a copy since I'm guessing that if you download Mt Lion now you'll get 10.8.2) or to Lion.

    Yeah , i guess so....

    Thanks for the help anyway.

    And when can i expect it to be available for download ?

    My mistake for the accidental slip with 10.8.3, been working with a bunch of Lion machines in the shop lately and they were all running 10.7.3. That being said, I don't even think 10.8.3 is available on the Developer portal, yet. No more mention of that, though, otherwise the forum police will bear on this thread with the wrath of the strength of 10,000 retirees.

     

    The issue exists in 10.8.1 as well from my experience. Our fleet of 13" Retina MacBook Pros exhibit the same issue that the OP is reporting (15-30 second shut down sequences). None of them run 10.8.2 because the update rendered the machines unusable, it's also why (I suspect) that Apple pulled the 10.8.2 for those machines. Personally I've noticed it on all the machines since the upgrade to Mt. Lion, it's just not that obvious on the MacBook Air due to the SSD (I suspect).

     

    Personally I'm curious to know what is that's happening in the background, the OS (at that point) has been secured and shut down. The only thing I've been able to correlate is that the more inactive RAM I had allocated at the time of shut down the more time it takes to shut down. I shut down all of my programs before shutting down the machine so my wired RAM is usually sub 1 GB (on 8 GB of RAM). Perhaps Mt. Lion is doing something with that RAM, a secure wipe or some other system level task.

     

    It's definitely a "feature" of Mt. Lion, though. Of the multiple machines I've tested that can run Lion and Mt. Lion the issue only occurs in Mt. Lion (dual boot).

    All but one computer I regularly use have SSD or hybrid drives and I seldom reboot or shutdown any longer. Um not true. My desktops start up and shut down on schedule so I never see it happen. But it did seem to me that 10.8.2 made the shutdown/restart time longer.

    What's not true? That the non-SSD drives take longer to shut down? That on the non-SSD machines it's not that obvious? The difference in shut down time between a non-SSD 10.8.2 machine is significantly longer than an SSD machine. On my Lion MacBook Air, the shut down process is 4 seconds with no programs running, on that same machine running Mt. Lion (10.8.2) it's 7 seconds. I don't consider 3 seconds to be "significant" in terms of time, do you?
