2012 Macbook Air Kernel Panics post after installing Mountain Lion

I recently purchased a 2012 13" Macbook Air. No Issues under Lion for over a month. After upgrading to Mountain Lion (and taking the firmware update to support power), I've been experiencing consistent shutdowns whenever I close the lid and let the machine sleep for more than a few minutes. I've been submitting the error reports and gave apple a call yesterday and we went through some troubleshooting steps but the problem has continued. Is anyone else experiencing this problem? Trying to figure out if it's a Mountain Lion or firmware bug that I will need to live with until a fix comes out or if it's possibly a third party software incompatability issue. Any help or thoughts would be greatly appreciated!

Hi guys! Just installed ML on my early 2009 MBAir (after market upgraded to a 240g SSD, but still just 2g of ram), and I panicked a bit at first when it turned out to be painfully slow and not displaying right (+slow trackpad!).
Bear in mind that the first thing ML will do is index your files for spotlight, which takes a while and is a bit of a resource hog that will slow everything else down and cause your machine to heat up.
I let it work all night, but by morning, my CPU usage was STILL at 100% and everything slow...
Activity monitor showed nothing over 10% CPU usage... First tip was to display ALL processes in Activity monitor, and not just MY processes, to see what exactly was sucking up my CPU!
Then, and it seems to often be the culprit on MBA's, it turned out that the kernel_task process was using up to 170% of my CPU usage (!). Problem is, that process sort of does a million things, so it can be hard to pinpoint the actual issue.
One of the things it does though, is work against overheating...
Given the download+install+indexing, my machine had been working all day and night, and was indeed getting super hot. Turning it off and letting it cool down for a whole fixed it all.
Kernel_task is back to normal, CPU usage is normal, display and trackpad are back to perfect. And in the end, ML is snappier than SL for me, even with the bare minimum in memory!
Good luck! <3

MacBook Air 2011 Fan increased after installed mountain lion

Hi all,
I have a Macbook Air 2011, Intel core i7. After when I installed ML I noticed that battery go down very fast (about 2:40h) and the Fan speed RPM is about 6500 all time, but I haven't any strong operation pending or App. I have the same app open since lion (Internet, chat, jdownloader) in background (skydrive,evernote,weatherhd) the same app and background task I have with Lion.
In monitor activity all task is from 1% to 20-30% of usage.
Any Tips?

I only have the fan kick in when the graphics is getting hit hard (playing games, driving external displays, etc) with crappy intel on board graphics.
Is your MacBook Air in a protective case, skin or having anything block the vent hinge?
Definitely sounds like the OS thinks it needs to keep running the fan.
You might try this smart temperature desktop widget and monitor your temperature to see if there is any sane reason for the fans to be on (they are loud!).

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

HT1338 Why is my MacBook Pro running so slow after installing Mountain Lion 10.8.

Why is my MacBook Pro running so slow after installing Mountain Lion 10.8. I have restarted, created more free space on my hard drive and run disk utilities. Simple operations result 20 seconds or more of the spinning wheel. Some are so slow that the operation does not happen at all. Itunes music cuts out during operations.

Check out this article by Thomas Reed for help http://www.reedcorner.net/understanding-upgrade-nightmares/. Also, make sure all apps are compatible with Mountain Lion using www.roaringapps.com. Do you have any antivirus installed? Make sure all apps are updated as well.

MacBook Air late 2010 very hot after installing Mountain Lion? Can i back to Lion?

My MacBook Air, late 2010, is very hot and the vans are going too speedy after installing Mountain Lion. Can I deinstalling Mountain Lion and returno to Lion? What are the steps for this deinstallation? Thank you.

Technically, there is a way, but it is definitely not something I would recommend, as downgrading isn't usually supported/encouraged.
I found a website that has instructions but it clearly states it's not for the inexpert, so proceed at your own risk. Also, I don't think you can download Lion from the AppStore anymore?

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install.

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

We're sorry.
We can't find the article you're looking for.
Please return to the Apple Support homepage.
Sigh.

Bluetooth inactive after installing mountain lion - your computer restarted because of a problem

Good day
I read up on forums, and I think my reboot error is due to my bluetooth that is inactive, which happened after installing Mountain Lion
My Bluetooth worked before under Snow Leopard
I have deleted the file under library to no avail
I have rebooted with cmd option P R to no avail
I have repaired permissions and this is the only message that pops up, and bluetooth still does not work after reboot.

This is not difficult and you will not have to download from the app store.
your computer has what is called a recovery partition that came with it.
simply hold cmd+R while you boot up. let go a second after you hear the chime.
you will boot into the recovery partition.
Use disk utlity to format your usb drive and then exit Disk utlity and go to Reinstall Mountain Lion.
it will ask you which disk you want to install ML onto. Choose your new USB drive.
easy peasy

Issue when updating my 2,1 Macbook Air from 10.6.8 to Mountain Lion.

I am trying to update my 2,1 Macbook Air from 10.6.8 to Mountain Lion however when I go to install it, it says "This update requires OS X version 10.8.". I cant see a resolution anywhere and so was hoping you guys could help?

Yes, and that's good and correct.
Now:

If the installation of ML doesn't start automatically after the download, you'll find a file named "Install Mac OS X Mountain Lion.app" under Applications. That will get it going.

Ethernet connection issues after installing Mountain Lion

After installing Mountain Lion I can't get my iMac to connect by ethernet. It says that no cable is connected. The cable/connection is fine. When I plug in my MacBook Pro running Lion, the ethernet connects just fine.

same exact problem. in fact, my iMac24 (2009) worked flawlessly until I installed the latest update to Mountain Lion. I then checked my MBAir (2011) and it too has a problem when using the USB/Ethernet adapter. Neither can get an ethernet connection. I deleted my network preferences and rebooted my machine, played around with my Ethernet switch and even reboot my gateway/router. I've never had to do any of this to my network until Mountain Lion. Wireless is the only thing that continues to work on both machines.

After installing Mountain Lion doesn't external hard drives mount or stay mounted. Anybody else with this major problem?

After installing Mountain Lion doesn't external hard drives mount or stay mounted.
I have tried resetting my Mac's PRAM but the problem still remains.
Even USB memory sticks are unmounted efter a few seconds.
Anybody else with this major problem?

I have the same problem, although mine has not been solved by ESET update, finder settings, PRAM & SMC resets or anything else.
Don't get it, my external hard drive still works on both my housemates computers - one macbook pro (with snow leopard) and one dell, just not on mine with mountain lion.
Any ideas for me guys?

My wifi is very slow after installing mountain lion on my Mac book pro

My wifi is very very slow after installing mountain lion on my MacBook pro.
What can I do?

Ha ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.

After installing Mountain Lion finder quits when I open desktop folder - why?

After installing Mountain Lion, finder quits when I open desktop folders. Not all folders.. I does it to new ones.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the name of the crashed application or process in the Filter text field. Select the messages from the time of the last crash, if any. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in the Console window, look under User Diagnostic Reports for crash reports related to the process. The report name starts with the name of the crashed process, and ends with ".crash". Select the most recent report and post the entire contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

Can't activate FaceTime after installing Mountain Lion

After installing Mountain Lion, I opened Facetime and attempted to activate it using my Apple ID, this was what I got:
"The server encountered an error processing registration. Please try again later."
I created a new Apple ID and tried again; same thing. I contacted Apple Support for help. After hours of instructions, reboots of my MacBook, reinstalling Mountain Lion, and a lot of patience later., the outcome was the same. It just couldn't be activated.
Today, I tried to activate Game Center, know what? Similar problem. This was the error message I've got:
"The requested operation couldn't be completed due to an error communicating with the server."
Any idea?
