Macbook Air startup slower after OS X10.6.7 combo update

[ZipZap]

There is a firmware update an other updates on the Apple site for MBA. Could not having these installed be an issue?

If you use Software Update the firmware updates should already be installed. The EFI 2.0 update a while back was for an earlier display-related wake-from-sleep issue.

when my boot was slow, i ran this on my 11" air:

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

put your password in (it doesn't type the characters so make sure you do it right), hit return and see what happens!

Type your password AFTER the first command (sudo...) and then run the 2nd and 3rd. You have to wait for it to run though, it might take 10-20 seconds. If you try to close Terminal and it says things are still running, don't close it. It should close without any message meaning the commands are already completed running.

This will fix your bootup time, 99.9% guaranteed.

No problem's with boot or running source games or anything else.

Well iTunes freezes my MBA. I was running it this morning without any problems. Did pram reset now going to run the usual suspects of disk utilities. May have to remove iTunes prefs as well.

I held down the shift key during startup to boot into safe mode. Ran permissions repair from disk utility. iTunes works fine now.

Yes! It works! I tried safe mode, clearing junk, removing login items, my boot time was 25-30 seconds. Now my restart time to wallpaper is ~16 seconds.
This is the solution, unless your hardware is bad

Since the update my mba has been slightly sluggish. Moving between spaces there is a jerkyness that wasn't present before and scrolling in webpages also seems to be effected.

I had boot up times close to 30 seconds. After doing the above, it is now back to normal Thank you!

Super. The three sudo commands on the cache cleared up my sluggishness totally on my original model MBA. Thanks.
