    There's a patch out for MBA 13" models running 10.6.7. Have you applied that?

    Did you do anything else? For instance, erasing the free space in Disk Utility will cause a slowdown in boot times. Downloading the TRIM Enabler discussed in the Mac Pro forum can help if you did that.

    Occasionally, an update will also cause the next reboot to take a while, but it usually fixes itself.

    The more we know, the more we may be able to help you figure out what is going on.

    I am getting my computer tomorrow, is this trim enabled something I want to use or is it speculated that apple will be bringing this in an update soon?

    TRIM will be active in OS X 10.7 (Lion), and possibly in an update for 10.6 before then. In the meantime, there is a thread in the Mac Pro forum with a link to a program that will activate TRIM on any Mac equipped with an SSD that supports it (including the late 2010 MacBook Air).

    That's still faster than most of laptops today. :p

    Mine is about 16 seconds.

    There are several threads showing that an update causes a temporary slown down of reboot times. The caches need to rebuild, just wait a few reboot cycles, and everything should be back to normal.

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

    paste that into terminal, enter your password and it should speed up boot time. (password doesnt show so make sure you type it correctly)

    My 11" ultimate boots and is ready to log in in 10-15 seconds, as did my 11" 128Gb 2GB

    I erased my free space in my Disk Utility and noticed a slowdown in both the bootup and the shutdowns. Is this gonna be permanent? Any solution for it?
