My bootup time is slower

[jlee6890]

I have the 13" Macbook Air (2010), 4GB/1.86GHz model and my start up time use to be 14-15 seconds...today its 25-26 seconds, about 10 seconds longer. Any idea as to why? My shutdown time is normal and has not changed.

Apple's way of hinting that you upgrade to Lion

Actually, we need more data. Did you recently install anything that'll auto-boot on startup?

how do you check this? Mine seems slower after only a month or so....

I can't remember, but I think I did update a few days ago. No application installations though for sure.

Flash problem

MacBook-Air seems very sensitive to Flash which auto-boot on start-up. I had the same problem and installed Click-For-Flash. Start-up time shortened and battery life almost doubled.

Sometimes updates can slow boot times for a few reboots. Also, you didn't do a secure erase, did you? That can also slow boot times. If you did the latter, do a search for the TRIM Support Enabler as that might help you restore your boot times.

There was a problem with iTunes updates some time ago which made Air boot slower...

Try this

open terminal and type (cut and paste the commands below):

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



*enter password after 1st command

Weird, it's back down to normal boot time of 14-15 seconds. All I did was shut it down and power it up a few times, then used my MBA as normal for a few hours, tried again and it went booted up pretty fast again.

what does this do?

I think I fixed mine - I loaded clamXAV and it was set to look for updates upon startup..that took a few secs...now about 17 secs...
