My three week old 13" MBA with 8 GB or RAM, 256 GB SSD and i7 chip has slowed to a painful 11 seconds start up/boot time, and and even crazier 21 seconds shut down time! My 2010 MacBook Pro is now officially kicking this brand new solid state machines' tail!!! Anyone else having issues or know a settings fix?
MacBook Air, Mac OS X (10.7.4), 2012 13" MBA, i7, 8GB RAM 256GB SSD
Downloaded Mountain Lion last night. Works pretty slick so far, no issues. Shut down times remain at 23 seconds after the upgrade, however, and my MacBook Pro, which I also upgraded, remains faster on the shutdown then the MBA. All programs continue to run at blazing fast speeds as well on the MBA. It is just shutdown that is very, very slow.
Well i experienced the relatively slow start up and the very slow shut down (app. 30sec.) after upgrade to Mountain Lion. I hadn't shut down until 30min. ago. and also sfter start up, to pen some programms, takes longer than usual. My MBA is only 16 days old....i think this has to do something with the new OS X.
Anyone experiencing the same?
My start/shutdown times got a little slower over the weekend after running Mountain Lion for a few days. Nothing dramatic, however. My wife's base MacBook Air, also a 13" and also brand new, slowed down to match my machine after the Mountain Lion download. So yeah, I'd say the new OS slows things up at first.
I too have the same issue. Downloaded ML today on my week old Macbook Air.... and the shut down takes 14 seconds as opposed to 3 seconds before the ML installation. I should have stayed wih Lion!!! Boot up time has marginally increased, about 13-14 seconds now.
I found that HP software is the problem, did you Installed some HP printer?
Sorry, The problem was parallels.
Thanks to 'Softwater' for pointing out Parallels. Yes, I am a Parallels user. This is what I did:
1. In 'Finder', clicked on 'Macintosh HD' under Devices.
2. Double clicked on 'Library'
3. Double clicked on 'LauchAgents'
4. Dragged three files starting with 'com.parallels.' to 'Trash'. Required password.
5. Repeated #1 and #2
6. Double clicked on 'LaunchDaemons' now
7. Dragged one file starting with 'com.parallels.' to 'Trash'. Required password.
8. Restarted the system. This is the last time system takes time to 'Shut Down'.
9. After restart, 'Shut Down' took just a few seconds !
We have to wait for 'Parallels' to come up with an update fix.
I do not have Parallels installed on either of our two MacBook Airs. Have it on my MacBook Pro and will keep that in mind if we slow down on that one. I DO have an HP wireless printer installed on the home network. That might very well be the issue.
I had the same problem since my MBA (i7 1.8Ghz + 4GB RAM) ran on Lion even before I installed HP software for the printer. I upgraded to Mountain Lion hoping it would fix the problem. I was wrong I had another with Mail as it would not connect to my yahoo mail anymore. 😟

My MBA also has a slow shutdown! i hate it! can someone pls help me
This solution worked for me. Thank you very much for your help! 🙂
Same problem. Macbook air is less than 3 weeks old and shut down slowed down after ML upgrade... No parallels installed as well. PRAM reset didn't work for me, so watching this thread for possible solutions to come.
Hi there,
I had the slow shutdown issue since the ML 10.8.0 upgrade. With 10.8.1 same thing.
And the issue was solved one day, about 10 days after the 10.8.1 upgrade without any specific action.
Last week, I have updated my MBP to get 10.8.2. After the installation I use Trim Enable to activate TRIM support again since I change my HDD to SSD (samsung 830). I rebooter the MBP to get the patch activated.
Once done, I noticed the slow shutdown was there again.
I had a look at many forums, no solution work, I did not test reset PRAM and other stuffs. I only ran daily, weekly and monthly maintenance scripts. But nothing worked.
Yesterday, I had a look to applications that automatically start at boot. I notice dropbox was registered twice. I deleted both entries, I re enable it from dropbox preferences.
I had a look at installed printers in the preferences. a Lexmark printer was set. I did not have this printer, a side effect from the vendor who installed my SDD. Hence, I had a check to declared wifi networks. Again, I removed the one of the vendor.
I shutted down my MBP, again 20s.
But after the next reboot, all next shutdowns are now about 3s as usual 🙂
No issue at all.
If you have the slow shutdown issue, try to clean useless printers and wifi networks, reboot and test the shutdown again... Maybe it will be fixed.
It's a low issue IMHO but I'd preferred have fixed this.
La Carotte.
Thanks very much for that. The slow shutdown was very annoying after just installing a new SSD.

I have a 2012 Macbook Air n even i have this problem after Mountain lion. I did a clean install once and fr the frst 3 days its boot was 12sec. and shutdown was 1 sec. But later it went back to status quo.
Hey, even I had the same problem.. my shutdown speed became verry slow..
well i found a solution...
goto finder >> goto folder (⇧⌘G) >> type in "/Users/username/Library" without quotes and replace username with your user name..
>>goto the Caches folder>> move everything to trash.. >> secure empty trash...
VOILA! Your air will now have faster shutdown times.. worked for me..
