    Not sure. But probably if you erase the drive and start over that may fix it.

    That's what I would do. Almost always a guaranteed fix. Nothing like a fresh install of the OS to clear things up...

    Hey , This Happened to me too and i found sth in the "Hello." user's guide that came with my macbook air ... Go to System Preferences/Startup Disk and click "mac os x , 10.6.6 or Macintosh HD" , click restart and then after the restart go at startup disk again and click at the chain there to keep settings like that , This worked for me , i hope it works for you

    The same thing (slower boot times) happened to me after buying a used MacBook Air 2010 I zeroed out the ssd using Disk Utility having selected "Macintosh HD" to erase. I went back to re-erase the ssd, but this time, I selected the "60.67 GB APPLE SSD TS0..." and under the erase tab, renamed the drive and it worked. My slow boot times were 30 seconds or so, now the boot times are back, at around 15 seconds! I hope this works for you.

    FIXED MINE...Here's How:
    First of all, I have a new MacBook Air (Purchased March 2011). All went well for a couple of week. I added programs and apps, and no problem. Then...I clicked the App folder at the bottom right of the screen and selected Utilities and then Disk Utility App. I selected my Macintosh HD and then the Erase tab and Erase Free Space. Well, after doing that my boot up time went from 15 seconds to nearly 40 seconds. I then began searching how to go about correcting this problem. (First of all avoid the problem by not erasing the free space, but if you already have, here is how to fix it.) Get the little USB chip that came with the MacBook Air. Turn off the computer, insert the chip, turn on the computer. Now select the option to reinstall the OS. Once it is done, turn off the computer, remove the chip, and turn it back on. Now, Click the little apple in the upper left of the screen and select the option to update software. When it is complete, you will see a number of things you need to update. If you try to do them all at once it may it may fail so just update the OS first and one update at a time. You do this by clicking the option at the bottom left of the update window and checking only one item to update each time. Repeat the procedure till all is updated. After that, I then still had some transparent icons in the dock so I clicked each and ran the program to make the icon appear. After doing all of that I restarted and found the computer would log out in a couple of seconds, as it had done when new, and logged back in quickly again - taking about 15 seconds. All was back to normal. This should work for you if you have erased the blank space on the HD like I did.

    "Ever since I upgraded to Snow Leopard 10.6.1, my MacBook Pro startup and shutdown was much slower than before.
    I searched for a quite a while on forums to find the solution, but nobody seemed to know a solution. I finally figured out what it was. It seems that somehow the ownership of my startup volume's root directory (/) wasn't assigned to the root account anymore, but to my account instead. This made the kernel prelinking fail since it requires that root is the owner.
    This is how you solve this after launching the Terminal app:

    sudo chown root:admin /
    sudo kextcache -system-prelinked-kernel
    sudo kextcache -system-caches

    You'll have to enter your password after the first command.
    Hope this helps someone, since it was really frustrating to have these slower startup/shutdown times for me."
