New MacBook Air 11 inch, 2013, Kernal_task running 300% constantly

I have just purchased a brand new MacBook Air 11 inch, 2013.
I noticed that the fan was running constantly when I booted up and have tracked it through the activity monitor to the Kernal_task which is eating up 300% on the CPU. I have no thrid party software or apps installed. It's brand new out of the box and the only thing that has been done is install the Mavericks updates as instructed by the apple update software.
And yet the Kernal_task still runs at 300% and the fan grinds on constantly regardless?!?
Is there anyway to fix this? Or have I got a dud model. It seems to be very strange for a brand new Mac to be like this. The fan and the Kernal_task as chewing through the battery and making the whole point of purching this Macbook Air a bit pointless.
Is there anyway to kill the Kernal_task without bricking my Mac?
Cheers,
S

Take it back for replacement since it's in warranty.

MacBook Pro 15-inch Early 2011 vs MacBook Air 13-inch 2013

Hello. I currently own a MacBook Pro 15-inch, early 2011 model. It has 8 GB of RAM, a quad-core, 2.3 GHz i7 processor, hi-res, anti-glare display, an AMD 6750m and Intel HD 3000. I bought it off of an Apple product store on Ebay about 3 and a half months ago. It was 1,350$. It was in perfect condition when I bought it, and it still is. I'm really into producing music, and I use Reason 6.5. I also do some other small things on my laptop, like word-processing, web-browsing and I bring it to school everyday. I was wandering if I should sell this laptop on Ebay, and buy a brand-new Macbook Air, 13-inch, 2013 model. The laptop is a little thick and heavy, and its battery-life is nothing compared to the MacBook Air. I really value battery-life I would probably upgrade the RAM to 8 gigs, and maybe upgrade the processor to 1.7 GHz, maybe upgrade the SSD to 256, but I might not. I was wandering if this would be a good idea. How much would I be able to sell this laptop for on Ebay? Is the MacBook Air weaker or stronger than the laptop I am using now? Screen real estate is something that matters a lot when using a music program, which is why I initially went for this laptop. Now, since the MacBook Air is smaller, I know that it displays just as much as this laptop does, so I don't think that the screen size would be that big of a problem. I am thinking about saving up for a 27-inch iMac, which would then be my primary machine, but if I were able to buy one, it wouldn't be for awhile. Anyways, Thanks to anybody who can help me!

Is the MacBook Air weaker or stronger than the laptop I am using now
Its stronger in alloy form factor, slim design with only ONE moving part, no HD to crash from mechanical failure of impact etc.
Ive got an Imac and current Air, and owned several Air, the air is the hands down choice for myself and I wouldnt part with it for any amount of money. Also own a couple macbook Pro, new and older one i rebuilt.
Here is an excellent video comparison between the 11” I5 vs. I7 2013 Macbook Air.

Macbook Air:
Only one moving part, ultrafast boot time SSD, the full power of laptop with the weight of an Ipad (close).
Air is the only Mac that has Haswell, 802ac wifi, and incredible 12hr. batt life in 13" I5. HOWEVER NOW the new Pro have 802ac wifi
Recommend buying the Air with 8gig Ram.
Pack around a regular laptop around about 20 days, then an Air, .....after that the standard laptops stays at home.
Only one moving part, the fan. No moving HD heads to crash or moving platters. Runs a LOT cooler than anything else out there (which = durability). Heater is a killer on a scale of 10X over that of accidents.
Also the AIR has far fewer parts to fail inside than a standard laptop. Really only a few replacement parts
The speakers on the Air, contrary to what most people would assume, are much louder than on the macbook Pro.
The Air in general is faster due to the SSD, also if you have a 802ac Router (i.e. Airport Extreme) then the Air over wifi is a LOT faster.
If youre going to be dragging a notebook around campus all the time, the Air makes things a lot more lovely.
The FINAL consideration of course is your application USE, and needs regarding same (see specs and video above)
The new Air, NOW with Mavericks is just 'king of the hill'. Nothing touches it

Nice to see you again.
The macbook Air is 'stronger' than the Pro only in terms of containing MUCH fewer parts, far less to fault, easier to repair
both have unibody aluminum alloy frames.

I have a brand new MacBook Air 11 inch, 4gb RAM and 256 gb SSD where the screen flickered abnormally and got dead all of a sudden while uploading a photograph in FB. Can anybody help?

I have a new MacBook Air 11 inch, 4gb RAM, 256 SSD and use Mavericks OS. It is still under waranty period.
Just few days ago while I was uploading a photograph in facebook, the screen started flickering abnoromally. I tried using the escape button but nothing was working so switched off by pressing the power button.
After few minutes I tried to switch it on but my system never waked up. Called up the Apple Support, did SMC and PRAM but nothing worked. Then I was advised to take it to Apple's authorised service centre.
At the service centre the engineers diagnoised and then said that the MLB/mother board needs to be replaced. Had waited for six-long days and today they had replaced the MLB/mother board. Now, the system came to life but nothing has booted. The screen goes white and a '?' question mark icon keeps on flickering.
After thoroughly diagnoising it the engineer said that now the problem is with the SSD and the worse thing is all my important documents and photographs etc are no more there. And I don't have a backup of the same!
While Apple Support contact centre is assuring they would replace any other parts if found faulty, but I feel differently. First, the MLB/mother board was changed now they say it is SSD problem - so if the SSD too is replaced there are possibilities of more faults coming up. All I can see and feel that this particular machine has turned out to be architectually deffective that calls for immediate replacement.
Right now I am using a friend's windows pc to write this mail.
Feeling completely miserable - all my expectatations gone after investing in such an expensive machine, loss of all my data, wastage of time and energy and to top it all affecting my daily work.
Can anybody please advise what shall I do?

Take the system to an Apple store to be fixed or replaced as the one you have has defective hardware.

I have a new MacBook Air 11'inch and I presume that it should come with the iLife programs. However, when I signed into the appstore with my account I have used with all of my Mac products, it now said I had to purchase each program, like iPhoto, iMovie, ect. seperate. I have already logged in and out of my account and called the "free" part of tech support. How can I reslove this issue?

Welcome to Apple Support Communities
If you really have a new MacBook, iPhoto, iMovie and GarageBand come with the Mac for free.
As you see their price at the Mac App Store, it's clear that there's a problem with your MacBook. Simply return it if you purchased it less than 14 days ago and you will receive a new MacBook

How come my Macbook Air 11inch mid 2013 is running very slow?

I recently bought it new, then couple months later, the fan would play very loudly, and everything went slow and laggy. I checked activity monitor and it says kernel_task is taking up a lot. Please let me know if there are any ways to make my macbook run back to normal, thank you!

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

My new macbook air 10.7.3 is running hot with the fan blowing just by using the internet. Is there something wrong with the computer?

My new macbook air is 10.7.3 s running hot, with the fan blowing after about one hour on the internet. It will also run very hot with the fan blowing when it is closed and in sleep mode, is this normal? My macbook pro did not do this.

May 19, 2012
My Macbook Pro 15" Early 2008 model had been running hot for a long time.
Checked Activity Monitor. (Applications/Utilities)
AdobeResourceSynchronizer was taking 83% of CPU usage.
Did a google search and found information regarding AdobeResourceSynchronizer causing high CPU usage and heat.
http://forums.adobe.com/thread/822790
Problem seems to be Adobe Resource Synchronizer.app
To disable go to: System Preferences > Accounts
Click the Padlock icon, enter password if needed, click Login Items,
uncheck AdobeResourceSynchronizer
I don't know how this got install on this computer.
I suspect Adobe Reader. AdobeResourceSynchronizer.app is within the Adobe Reader application package.
Control Click (or right click) the Adobe Reader app, click Show Package Contents
Location: Applications/Adobe Reader.app/Contents/Support/AdobeResourceSynchronizer.app
Some other Adobe applications may also cause this to run.
After disabling this in System Preferences > Accounts, temperature seems to be acceptable.
Also start Adobe Reader X, go to Preferences, Tracker and in the "Automatically Check for New Comments and Form Data", slide the top slider all the way to the right so is says Never.
After having done all this and restarted the computer, check Activity Monitor again and see if
AdobeResourceSynchronizer is still running. If it is you can click on it so it is highlighted and click the Quit button in the upper left.
This solved my excess heat problem.

If i purchased a new macbook air in september 2013 will i get iworks and ilife for free ?

normally apple give 2 months

I had iWork 09 installed from physical copy and I tried to buy Page 2013 for 18€.
The appstore took my 18€ and let me download page (obviously), numbers and keynote for free as an update for my previous apps from iWork 09... *** ?
I didn't want to pay anything because I own a Macbook Air (bought in september) but they already took my money :'(

New MacBook Air 13-inch - A **** ton of problems after new IOS

K, I just got a MacBook air, not even two weeks ago. First off, I`m a really apple fan, I`ve always liked, specially because of the well constructed integration between hardware and software, but seriously, the previous week has been a COMPLETE nightmare with this computer..t
Just to make it short the number of problemas that are completely driving me crazy and making me consider just giving up this computer
1) ******* google hangouts and skype not recognizing the built in camera on the MBA..
2) NUmber 1 leads to number two which is FaceTime is a pathetic program.. Two main reasons for that are a) quitting unexpectly for no reason, b) sound works fine for 2 minutes and than the sound glitches starts (possible to see at utilities > console)
3) The flash conflict with Google Chrome that makes the freaking sound to keep popping every 3 seconds...
If everyone has any solution for those problems, PLEASE, help me..
I`m really trying not to hate apple..

With flash I had to install is seperate from my browser (Firefox) to make it work properly. Normally you can just download it from your browser with no problems, but on this machine (I got it as a replacement on Sunday) I had to download and install is seperate to make it work properly.
I would try uninstalling both and reinstalling them again just to see if that makes a difference as well.

New MacBook Air 11 inch Battery Problems

I just got my new mac book air home and ran a full charge into the battery. Once i disconnected it from the power adapter i noticed the battery was still only showing around 4 hours of life. Nothing was running on the matchine at the time, other than a wifi connection.
As I started to use the machine (writing an email in a single browser window) the batter indicator began to jump in a seemingly iratic way. After 30 mins of use, the batter indicator was showing less than 2 1/2 hours life remaining.
I've run the latest software updates and the same issue persists. My machine is an 11 inch 1.6GHz model running the i5 processor. I can see a few people have had issues in the past with eratic battery indicator behaviour but cant see any difinitive solution?

There is no definitive solution. The time remaining indicator provides an estimate only based on the current load on your system. When you first start using it, there will be more activity than normal as your system is set up and Spotlight indexes your files.
Think of your computer as being a car. If you're going along a flat road, you can keep the gas at a steady level. At that rate, maybe you can get 100 miles out of the gas you have remaining. Now, if you suddenly go up a steep hill, you're going to have to use lots more fuel and all of a sudden, you may only get 50 miles out of the gas you have remaining.... but if you get to the top of that hill and then start coasting down, you might be able to get 200 miles out of the gas you have remaining. How many miles you can get out of the gas you have remaining will always change if you measure it by what your car is doing "now". However, if you look at the gas gauge instead, it will not fluctuate that way... it will always show you how much gas you have remaining.
To get the same accurate "gas gauge" reading, you should view your battery by the percentage remaining vs. the time remaining. The percentage remaining is the "actual" percentage of your charge remaining. The time remaining is only an estimate based on your current usage and it can fluctuate wildly depending on what your system is doing.

Should I buy a new Macbook Pro 13 inch or Macbook Air 13 inch?

Hi,
I was wondering if I should buy the new Macbook pro 13 inch, or keep my old 2010 1.4 C2D Macbook Air. I am not satisfied with the tiny 64GB SSD that my current Macbook Air has, because just a few weeks after I had done a clean reinstall of OSX Lion, the whole disk almost filled up. The one thing I do like about the Macbook Air, however is the speed of the SSD. Its really quick, and it boots in under 20 seconds. The Air didn't have many performance issues (other than overheating like crazy after playing a few graphics-intensive games).
If I were to buy a new Mac, my price range would be from $1200-$1500. I plan to use Garageband/iMovie frequently for making Youtube videos/school projects, and store a large music library. I also plan to do some moderate gaming and run Windows 7 in Bootcamp/Parallels. I don't plan to take it around much, but I don't want to have to weigh down my backpack in case I have to. My two options now would be the new Macbook Pro 13 inch or the new Macbook Air 13 inch. Could anyone give me a suggestion of which computer to buy?
Thanks!

I went through this same thing when I purchased my first Mac 3 days ago, also between the 13 inch MBA and MBP. I ended up deicding with the 13inch MBP, here's why:
1. More hard drive space, yes it may not be an SSD but more space is more space. I have also heard about people taking out the disc drive and adding an SSD in its place, so there would be an option.
2. The disc drive, I rarely do use it but just in case it's there and easier than carrying around an external.
3. Upgradability, I plan on keeping this Mac for a while because I spent so much on it. On a MBP I can upgrade the internal parts such as the hard drive and RAM. On a MBA everything is soldered together so what you buy is what you stick with.
4. Ethernet port, this is one that could be gotten around by an adapter but I still took it into consideration. Not everywhere has wifi yet including my work where every computer is hard wired.
5. Bootcamp, as well I plan to run Windows 7 on mine and Windows 7 takes a good amount of space so this is another spot where the larger hard drive of the MBP comes in handy. You could always have an external hard drive and run Windows 7 off of that on an Air but then you would have to have it always plugged in when you wanted to run Windows 7.
About me, I am a student so I had a lot to think about and read a lot of reviews online before I decided on my MBP but I am glad I decided on this over an Air. It may be a few pounds heavier also but in the long run for me I think the Pro will be better, I do plan on adding more RAM in the future as software becomes more memory intensive. With you're pricerange being 1200-1500 the 13inch MBP with the i7 processor may be one to look at. From Apple with their student discount, if you are one, you get $100 of plus a $100 giftcard. At BestBuy (where I got mine) the price of the i7 13inch MBP is 1,424.99 and if you're a student you get $100 off but no giftcard. I got the i5 13inch MBP because I don't need an i7.
In the end it all comes down to what works for you, but I hope I was able to help you some.

Macbook Air (11 inch) does NOT go in hibernation mode when battery runs out

Hi,
I have a problem with my new Macbook Air. When the battery runs out to 0% it does NOT go into hibernation mode, it just turns itself off and all my data is lost. It never happened to my old 2008 Macbook Air!
I have all updates, the 1.4Ghz Macbook with 4GB RAM upgrade in case that matters. Hope anyone can help? Is there perhaps a setting where I can set at which Percentage (%) the Macbook should go into hibernation? Thanks in advance!

Noone knows a solution? I also still have problems with my Macbook not waking up properly (like everyone else). The main problem is, however, that it SHUTS down when the battery is empty and does not hibernate!
And I can't install the MacBook Air Late 2010 Software Update 2.0 - I always get this message: "MacBook Air (Late 2010) Software Update can’t be installed on this disc. This volume does not meet the requirements for this update."
- The update also does not show up in Software Update, I had to download it manually!
And I believe its NOT because I have 10.6.6 because I have talked to others who have the same problem under 10.6.5!

New macbook air eye strain

I used the 2010 model macbook pro 13 inch for the last two year...sometimes up to 12 hours a day with NO issues at all.
thursday I switched to a new macbook air 13 inch. Now I get horrible eye strain and a headache after 20-30 minutes.
Any ideas on what I can do to fix this? are the displays different?
If it doesn't get better i'll have to return the device. Its that bad!
Any help is MUCH appreciated

Hey jss. Well, same results at 1920x1200 as when the MBPr is in the retina display setting (1440x900). My vision gets blurry after working for a few hours when I look around at anything other then the laptop. It takes about 30 mins away from the computer to get my eyes to sort of refocus. And then left with a mild headache the rest of the day. So, I've decided to return it.
What is confusing to me is that if my eyes have a problem with the LED backlite and this screen tech has been in place since the overhaul in 2009 (???), why don't I have problems when working on my early 2011 17" MBP? Maybe its simply due to the 17" of space. After carrying around the MBPr, I don't want to return to lugging around this beast again. I'm going to check into the anti-glare 15.4 since I believe it uses different tech for the screen.
There are more threads on this subject in the forum, so it seems its something Apple should spend some time researching. It may not be a huge problem, but the number of people complaining about this problem seems to be on the rise.

Phenomenal new MacBook Air! WOW!

I have just received my new MacBook Air 13-inch, and I have written this post to let you know that it is truly amazing.
My heart belongs to the MacBook Pro line, but I just love the Air for short travel.
I have maxed out the specs, which I strongly recommend. It is lightening fast!
I had been really worried about having over 150 GB transferred from my MacBook Pro, as I have always loved FireWire target disk mode, but transferring via the USB Ethernet adapter is impressive. What had taken a little over an hour via FireWire target disk mode had taken me just over three hours via Ethernet.
I do not want to do that everyday, but I am quite happy.
The speed just rocks!
I had purchased the original MacBook Air only to mothball it a few months later. This new MacBook Air works for me very well.
I still do not trust flash/SSD storage, but I am willing to get my feet wet with the new Air.
Anyway, it does not seem that there are differences between the new and old MacBook Air power cords. Is it safe to use a first generation MacBook Air power cord with the new model? One can do this with MacBook Pros, but I just want to make sure.
Thank you!

My new macbook air storage keep going down without doing anything.

so, i got a new macbook air 11 inch, 120 gb. i set it all up and stuff and when i check my storage i only got 99 and stuff left. how can that be? i didn't download anything, all i did was set it up. I download stuff and delete it so my storage keeps going up and down. Then one day, i have to restore my cousin's iPad for her using my macbook which has 99 something gb, then after that's done, the storage goes down to 93 gb. Seriously, i didn't do anything. please explain to me if the stuff i do takes storage or not becauseI have to save storage for school works. Thank you for reading

Move your cursor up to the Apple menu and select About this Mac then select Storage from the options at the top of the dialog box that opens. This Spotlight view will show you how much of the drive is being used to store Applications, Files, Music, etc. Other is something of a catchall group so it doesn't really help.
One explanation for the "missing" space is Backups. If you are using TimeMachine the computer will make backups to the internal drive whenever it isn't connected to the TimeMachine drive. This 'missing' space really isn't missing because if you really need it the computer will automatically delete the internal backups to free it up for you.
Another explanation are cache files and system logs. Your programs and the operating system need to keep temporary files and they aren't always immediately deleted. Your browser(s) also create cache files which makes your internet surfing experience much faster for sites you frequently visit. These caches can be quite large.
To delete/trim system and application caches you can restart your computer while holding the shift key. This is a safe boot and among other things it will delete/trim caches. Reboot normally once you get to the Finder. Also, remember to empty the trash can - putting stuff in the trash doesn't immediately delete it. If you use iPhoto you must manually delete its trash too.
