Macbook pro 2010 with SSD running mountain Lion - Increased shut down time

Hey guys,

I recently carried out a clean install of mac os x mountain lion on my Macbook pro 2010 with 256 GB SSD. I came across this issue where my shut down time was significantly increased (i.e more than 5-10 seconds) but my start up time was normal as before. I tried to figure out what might cause the lingering shut down with the spinning wheel apperaing on the gray screen but the Console report shows no significant errors or lingering applications

I did some research online and use the follwoing commands:

cd /
sudo chmod 1775 .
sudo chown root:admin .

When I entered the second command i get the following error: Can this explain why my computer takes long to shut down?

Kernel file /mach_kernel does not contain requested arch: i386

Hope someone can clarify this up for me. Thanks in advance

 

Have you made sure that you have un-checked the option to save the state of computer when closing so that your computer starts off where you left off (opening up a browser or a specific program in a specific state)? A clean install automatically sets it as default, though It has never came on after I unchecked that box. I have an SSD, so I don't have to hibernate (however many seconds it shaves off on a regular HDD start up...) so I just start off fresh.

Generally, my shut down time has become longer compared to Lion while the start up time has shrunk by a 1-2 seconds. I ain't complaining considering that I still have space left over on a 120 gig drive after have 40+ gigs of files and the system. I had issues on my Mac before where I was considering swapping out for a bigger drive since I had computer crashed where I had run out of page file space. I think that this is one area that windows might learn from Mac.

 

Thanks for your reply mate. Can you please tell exactly where to find this option you mentioned in your first paragraph?

Also, i did more digging around and came across these commands and tried them out and shut down time dropped significantly and its back to the normal state. Maybe you could give it a try and see if it helps you out.

sudo defaults write /System/Library/LaunchDaemons/com.apple.securityd ExitTimeOut -int 2

sudo defaults write /System/Library/LaunchDaemons/com.apple.coreservices.appleevents ExitTimeOut -int 2

sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ExitTimeOut -int 2

sudo defaults write /System/Library/LaunchDaemons/com.apple.diskarbitrationd ExitTimeOut -int 2

sudo defaults write /System/Library/LaunchAgents/com.apple.coreservices.appleid.authentication ExitTimeOut -int 2


Make sure to quit terminal after this and then enter the following:

cd ~/Library/Preferences/
rm com.apple.desktop.plist
killall dock


These commands did make a significant different and it really brought down the shut down time down. Also, lemme know where to find that option you mentioned?
