    I have noticed a big increase in the amount of time Mountain Lion takes to power down over Lion. It use to shut down in a few seconds. Now it is taking on average around 25-30 seconds. Anyone else experiencing this?

    I think Apple have removed shutdown monitor logging -- this used to work in Lion but is empty in ML ( > shutdown_monitor.log)

    You can try to reboot in verbose mode (⌘v on startup), and see what is shown in the shutdown text. You'll probably see some processes which do not unload properly...

    I've noticed this as well. It's been this way since DP 1. Hopefully we'll see an improvement in 10.8.1.

    I found that my locally attached Time Machine drive does a lot of cleanup sometimes when I power down. If I am remote and do not have it attached, it can shut down in very few seconds. If I am at home and have it attached, sometimes it can take 30 seconds or more.

    I did an upgrade. I did not want to take the time to do a clean install but I might to see if it fixes the problem.

    I use a Time Capsule to it's always remotely attached. I just have never had it shut down in a few seconds anymore. I haven't noticed any system slow downs when it's on as of yet. Start-up is still 10-12 seconds for me.

    I did a clean install and am still experiencing very slow shut down times. My mid-2011 MBA 11" used to shut down in 2-3 seconds on Lion. Now it takes 20-30 seconds to shut down on ML.

    I have the same issue - it's gone from ~1 sec (Lion) on my Late 2011 MBP 13 with Sandisk Extreme SSD to ~15 secs. Once in a blue moon it will shut down in around a second but the majority of the time I have the grey screen with the rotating shutting down icon. This happens even when I boot up and then shut down without opening up any applications. The only 3rd party app I have running in the menu is caffeine.

    My MacBook Pro was taking around 15 - 20 seconds to shut down, it was literally 1 second previously under Lion - SSD installed and this was pretty consistent. It would do this 9 out of 10 times.
    As of today, it appears to be back to shutting down in 1 second - I don't want to speak too soon but I have shut down 3 times today and it's been 1 second each time. So what has changed? Well this morning I had an HP Printer update under software update - perhaps this has been the cause for me. If anyone else has an issue and has been using an HP printer then I urge you to try software update and install the update to see if this fixes it for you.

    i just installed that update myself, unfortunately its still taking between 20-30 seconds to shut down, even after a start up without opening anything.

    its so annoying, never saw the spinning wheel on shut down before ML

    So has anyone tried using verbose boot to see what is causing your slow shutdown?

    Heh -- every time I try verbose mode (command-V on startup) it shuts down in ~1 second, and then the one time I decide not to verbose mode... :eek: I'll keep trying every now and then.

    Hopefully we can find something before the Windows 8 folks arrive...

    Mine has been back to ~1 sec for well over a week now since I installed that HP update. Not sure exactly what the trigger is but it seems to be fixed 100% for me now. Actually nervous about installing 10.8.1 when it comes out now.

    my early 2011 macbook pro takes anywhere from 30 seconds to 2 and a half minutes to shutdown both on a HDD running at 7200rpm and on a sata 3 SSD.... though i recall having this issue was back since DP1 aswell.

    Mine is having the same problem, it took 25-30 sec to shut down, but when I did restart my mb pro, try to shut down again, it back to normal, 3 sec..anyone has the same problem?

    I have a new rMBP and I've been noticing this, too. Not only are shutdowns very slow, but the same is true of restarts. The shutdown takes a long time, and then the computer stays off so long that it appears the restart isn't even happening. I had about a 15-second delay yesterday between a shutdown and the startup chime.

    It seems like my slow shutdowns have been after I've had peripherals attached (iPod, Thunderbolt-to-FireWire adapter, etc.). If I use my rMBP without any peripherals and then shut down, it's usually very quick (1-2 seconds).

    I think everyone in this thread has collectively spent more time thinking and typing about this "problem" than the increase in shutdown time has ultimately cost us.

    You listen Mister, shutting in 3 seconds in Lion was super impressive to me coming from Windows. Now I'm back to 20-30 seconds shut down, especially when I'm about to go to bed, is annoying.

    The solution

    I had the same problem on my MBA runing OS10.8 (and Lion)

    I found this solution on another site

    navigate to the Macintosh HD on your desk top open it go to libary and delete the Java folder then empty the trash can

    You dont need the Java files and if you do visit a site requiring them you will be prompted to down load them and they will be the new ones.


    Try it it works

    Hey all,

    As I posted in my own thread (sorry didn't see this one), here's the main issue I find with verbose mode on during shutdown:

    Anyone provide enlightenment?

    appleid.authentication indicates to me some problem centred around user accounts.

    I have just posted the solution to slow shut down times in OS 10.8 above

    Works fine and no I dont claim it I found the solution on another Apple forum

    So all you peeps should be shutting down in about 3 seconds now!


    fiveainone the problem is the OLD Java file that have been carried over from Lion slow the shutdown of Mountain Lion - get rid of them and you are back to a fast shut down any new java files you download if needed will be fine with OS 10.8 and will not slow you down as the ones you deteted currently are.

    If you are worried save the Java folder to a USB stick!!

    I have never installed Java on my system so that is not the problem.

    I was having the same problem. I recently bought Intel 520 SSD and installed ML onto it. The shut down for me was slower than my old HDD with Lion.
    I had cleared my LaunchAgents/LaunchDaemons and also used CleanMyMac to clear cache files and logs but that didn't do much.

    It took me a while to fix it, but believe it or not this worked for me:
    1. Shut down your computer with "Reopen windows when logging..." CHECKED. (The shut down will be slow this time ~ 20 seconds)
    2. Turn your computer on
    3. Shut down with "Reopen windows when logging..." UNCHECKED. It now shuts down in 2 seconds.

    Good Luck!

    This works for me, unchecking "reopen" means a 1-2 second shutdown. I wonder why? Issues with permissions and exiting apps?

    I would not recommend CleanMyMac, based on the number of complaints that have been posted in this forum and elsewhere. As an example: CleanMyMac cleaned too much. While you may not have experienced problems yet, enough people have that it's wise to avoid it, especially since there are free alternatives that have better reputations, such as Onyx.

    You don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process.

    These apps will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space. In fact, deleting some caches can hurt performance, rather than help it, since more system resources are used and performance suffers while each cache is being rebuilt.

    Many of these tasks should only be done selectively to troubleshoot specific problems, not en masse as routine maintenance.

    Mac OS X does a good job of taking care of itself, without the need for 3rd party software. Among other things, it has its own maintenance scripts that run silently in the background on a daily, weekly and monthly basis, without user intervention.
