Macbook Air constant kernel task and random reboots problem

Hi my Macbook Air has suddenly started playing up after being fine since purchase. While engaged in photo editing in Photoshop a couple of days ago the fans were screaming flat out (not so unusual) but I had a look in Activity Monitor and noticed an ongoing Kernel Task, I never usually see these but now they always seem to be running hogging (at the moment 608 MB of) memory. Now today the machine has shut itself down twice too something that has happened once or twice only in the last two years . I reset the NVRAM but the kernel task is still running.
Any clues what to do next? Could it be 10.9.2 related?
Thanks
Simon

The kernel_task (pseudo-)process is always running. It should not, however, be using more than a few percent of the CPU. Is it?

The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
1. You don't own another Mac.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
2. You do own another Mac.
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.

My Macbook air (late 2010) shuts down randomly!!

Need some help here!! My Macbook air (late 2010) shuts down randomly, sometimes it won't even power on. This happened to me one morning, then at night try turning it back on, it went back to normal, I didnt do anything to it. Today it did it again but it went back to normal few minutes later after hitting the power buttom more than 10 times

Hi Argenisss,
I'm sorry you are having issues with your Macbook Air. Since your post indicates you have the latest version of the operating system, I would suggest resetting the System Management Controller (SMC)
Intel-based Macs: Resetting the System Management Controller (SMC)
Power
The computer doesn't respond to the power button when pressed.
A portable Mac doesn't appear to respond properly when you close or open the lid.
The computer sleeps or shuts down unexpectedly.
The battery does not appear to be charging properly.
The MagSafe power adaptor LED doesn't appear to indicate the correct activity.
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Another troubleshooting step would be to reset the PRAM as well:
About NVRAM and PRAM
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
You can read more details by clicking on the two links above, but these would be two good troubleshooting steps to try.
Hopefully, this information will help ....

I have a problem syncing iCal on my Macbook air (10.7.5) and my iPhone 4s (5.1.1) over iCloud. The following server error message comes up "The request (CalDAVAccountRefreshQueueableOperation) for account "iCloud" failed." Been to Apple - no luck. Ideas?

I have a problem syncing iCal on my Macbook air (10.7.5) and my iPhone 4s (5.1.1) over iCloud. The following server error message comes up "The request (CalDAVAccountRefreshQueueableOperation) for account “iCloud” failed." Been to Apple Store - no luck instore, or with Super genius over the phone when with genius in store, taking data in real time via ethernet!
I had to do a full wipe of my system because of time machine back up issues 2 weeks ago, and the error has only occured at some point since then. I only did a drag and drop of my user account folders/files into an External HDD rather than a copy of my user account (advised by the staff in store at Apple to do this) and when reimported, the Mail folders are all present but each message is in a sub-sub-sub folder that is numerically named. I do not have a mirror image of the hard disk prior to the wipe, only a time machine back up from 2 weeks prior to it being done. I am uncertain if this reinstall has caused the issue.
I am not happy to upgrade the software in my iPhone until I have the calendars working. I have purchased Mountain Lion, but again am concerned about upgrading until the issues are sorted.
I have tried the other solutions on here with no luck. HELP please.
Many Thanks.

Progress Update.
I made a back of what existing phtos and Videos I had on my Iplhone. I used Image capture to do this making an entire back up of photos and videoa that were still intact on the phone.
Image capture is god for this purpose, as it does exactly what you ask it to do without applying any rules or squishing the files back into iphote (which might also be corupted)
Image capture wil do the basic function of retriving the contents of the phone and save them as native files on your hard drive.
Once I did this I erased my iphone, and re intitialised it restoring an older back up from icloud.
As the retore was happneing - I did retreive the missing files that cuased the intial beviour as above, and I could play the videos that were missing in the above scenerio. The wierd ting was however that even though the source files were now back on the device, the thumbnail previews were missing. Where I ahd balck thumb nails for server portions of the resotred content.
I then went to bed as the restore is a long process. When I woke up the library had library had cleaned itself up. Mysteriously the prcess had deleted the files missing the their thumbnails.
This is very perculiar and bad behavior.
I am now repeating the process, and will attempt to download the missing content as it is restored and prior to the phone trying to fix itself.
Here are the lessons learned.
DO NOT rely on Photo Stream to keep back ups and synchornise videos from you IOS device. IT DOES NOT SUPPORT THIS CAPBILITY
DO NOT rely on iCloud Back Up alone - always fd an occassional iTunes back up or more reliably still always take a back up of photos and video files using Image Capture to be doubly sure that you a have backd up any content.
DO THIS NOW - dont wait to loose your phone ofr have your phone repaired by replacement at the apple Store. (I did both :-(

After some advice, I am new to Apple and looking to purchase either the MacBook Air 13inch with 256GB and 8GB mem or the MacBook Pro 13inch with retina 256Gb and 8GB mem. I am an assistant principal in a primary school and also studying my masters at university. I don't play computer games and I don't watch movies. I do store photos and videos of my kids and music on iTunes. I also like browsing the net with numerous windows open, check email etc. I am really wanting long battery life as I do a lot of my work on the couch - not close to a PowerPoint. Would the air do the trick or will it soon be outdated as Apple move towards retina display? Both air and pro seem very thin - almost the same? And not much difference in weight either so both very portable which is also a necessary requirement. Just can't help dreaming about that 12 hour claimed battery life. Any helpful advice/opinions, very much appreciated. Thanks

It's not likely that you'll get 12 hours in reql life. Those benchmarks are set under very strict controlled conditions. Kind of like mileage per gallon claims on cars. If 16GB of ram is an option at all I'd highly recommend you get that. As far as storage 256GB isn't alot, consider storing some things on an external thunderbolt real

My Mac is running INCREDIBLY slow, Kernel-task and LR, PS, PSE, etc. are not functioning well.

Hi! Been trying to follow a thread about the Kernel-task and slow Mac performance. I did download EtreCheck and ran the report. I am a photographer using LR 4 and Chrome is my main browser. Both Chrome and LR (or PSE, or PS or Xee (a photo viewing app) make my computer run beyond ridiculously slow. I have so much work to do for clients and I get stopped in the middle of editing and cannot move forward because my beloved Mac is having issues. I did go through several old apps and the Application Support and Prefernces and deleted what I could of what I knew "what was what". I would appreciate any help in getting my Mac back on track. Thanks!

Problem description:
My Mac is running incredibly sluggish. Chrome continues to lag, and the spinning ball is ridiculous when I am working in LR. I did the EtreCheck and the report is below. I JUST cleared out my LR catalogs and now have just two folders in the catalog from a current wedding I am working on. I will have to consider using separate catalogs for my other genres or even smaller catalogs and just make a catalog for each client. Thanks for looking this over! I am so frustrated.

Several problems exist.
1.
Back up your Mac prior to making any changes to its file system. Time Machine has not been configured properly To learn how to use Time Machine read Mac Basics: Time Machine backs up your Mac - Apple Support.
2.
You inadvertently installed adware. You do not need to download or install anything to fix it.
For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware. Apple's instructions are linked in the Recovery Procedure near the end of that document. Read and follow them carefully. Pay particular attention to the easily overlooked passages directing you to restart your Mac when required.
3.
That Mac's Hosts file appears to have been modified. Fixing a modified Hosts file requires specific instructions. Apple Support Communities contributor and EtreCheck author etresoft recently added a User Tip discussing that concern, and how to correct it: Fixing a hacked /etc/hosts file

I'm relatively new to Mac and want to try and get the most out of the new MacBook Air.
My wife and I have been sharing the same Apple ID. We both have iPhones - she has a 5 and I've got a 4S.
We only have one copy of iTunes and we have been sharing the account. (She doesn't really use the computer for anything beyond writing the odd weekend assignment.)
Would I be better off setting her up with her own and making her as a separate user on the computer? Would this require much work?
In recent times with updates, we have a few problems with the duplication of texts and that sort of thing. Both of our texts are stored on the computer and that sort of thing. Also, sometimes texts I send her are sent through to me from her, if that makes any sense.
Anyway, I don't really want to overly complicate matters when it comes to accounts etc, but I wanted to know if a fresh Apple ID would be the best thing or even a new user?
Any tips etc would be greatly appreciated
Thanks in advance

I have this question too (0) Reply

Your question is almost too much a personal one, begging the question "do we (husband and wife) feel comfy sharing one account on the Mac"   maybe thats why nobody answered you.
It doesnt complicate anything, but it adds steps for switching accounts on the Mac/ purchases etc. of course
since your question is mostly personal, ..I wont answer THAT part of it, but creating a new account is easy.....messing with switching back and forth is also a personal preference 'issue' as well.   I prefer to keep things simple, but...........you and yours, I dont know.......

How do i copy content from one hard rive to another through my macbook air? the copy and paste option doesn't work

How do i copy content from one hard rive to another through my macbook air? the copy and paste option doesn't work

It's because of the extension of the hard drive is a Windows extension ( most likely MSDOS or Ex-FAT), meaning you can only read but not write. If there are no important files (or you can copy the whole thing to your computer/mac) you can just reformat the hard drive and change the extension to NTFS (readable and writable on both windows and mac) or Mac OS Extended (readable and writable on Mac, readable on windows).
Go to DISK UTILITY
Choose the Hard Disk you intended
ERASE
You can choose either
(I personally prefer this one, you know just in case)

I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

Could you show me the detail of the MacBook Air md226x/a? And why is the model number different with another Air?

Search for MD226x/a on Google.

This problem is often caused by "Google Drive." If it's installed, I suggest you first check for an update. If that doesn't solve the problem, remove it according to the developer's instructions. You may need to boot in safe mode to do so. Back up all data before making any changes.
If you use Google Drive and don't want to remove it, then try deselecting the option in its preferences to "show status icons." According to reports, that may be enough to stop the Finder from crashing.

HT201364 I have a macbook air bought in 2008 and am unsure if it can be upgraded to maverick. Is there a serial number beyond which it is OK?

The model identifier is MacbookAir1,1

No that system will not run Mavericks.

MY NEW MACBOOK AIR IS HEATING UP AND ITS BATTERY IS DRAINING OUT REALLY FAST

MY NEW MACBOOK AIR IS HEATING UP AND ITS BATTERY IS DRAINING OUT REALLY FAST. WHAT TO DO? I BOUGHT IT JUST 5 DAYS AGO.

If you are within the 14 day purchase period you can exchange your MBP for a replacement. If not you can have it checked out at the Apple store genius bar.
CPU intensive applications will place stress on the CPU/GPU which will create heat and speed up the fans. That is normal. If you will, download from the Internet iStat pro and install it. When your MBP gets hot, post an image such as this from mine:
Also open Activity Monitor and set to show 'All Processes' and '%CPU' to display values from high to low. Post that as well like this:
From this information we may be able to tell if there are any issues or not.

Macbook Air gets really sluggish and incredibly slow

Hi, my Macbook Air bought last December (2008) becomes very sluggish, as in really slow after some very light usage.
It usually happens when I'm watching a YouTube video (or any .flv video) in either Firefox or Safari or if I'm browsing for a long period. It's not just the browser that becomes slow, it's the whole computer. The video cannot be watched and it becomes all jittery. Switching between tabs takes a while, and even scrolling down a page has a delay. Typing also has a delay, and the whole experience is just horrible. Moving along the dock, the icons magnify at irregular intervals and launching an application takes extremely long, even the System Preferences Pane.
The happens whether I have three or four applications open with twenty tabs in Firefox or with just my browser and only two tabs. Along with the sluggishness, the fan starts very loud and to get rid of the slow behavior and loud fan noise (the noise wouldn't bother me, but I associate it with slow, slow problems) I have to flip the lid down and leave it go to sleep. When I return, watching the video is ok for a while, but if I have to pause it to do something else or if I do something other than view light web pages like change tabs, the computer slows again.
It's a Macbook Air 1,1 with a 1.6GHz processor and 2GB of ram. I have 50GB of the 73GB of hard drive space empty.
I recently updated it and left if off for a couple of days, but this hasn't helped.
There are only two applications which open when I log-in also, so I have no idea what the **** the problem could be.
Any ideas, and what could I do to fix it?
Your help is EXTREMELY appreciated by this very frustrated Air owner!
Thanks,
Ed.

My first generation Air was sluggish from day one. Part of the problem is overheating, you can see that in the Activity Monitor as process 'kernel_task' taking 150% CPU or more. My fist generation machine crashed a lot, but that was eventually fixed with a firmware update that I suspect made the machine even slower. If I lift my machine up and hold it against a table fan, I can watch the 'kernel_task' CPU % claim down to almost zero.
I suspect another defect with the Air is the disk I/O system. I know the disk is not supposed to be the fastest, but if you have one application that do anything on the disk, everything else slows down to a halt. DMA (direct memory access) was invented 1989 or earlier, so I really don't know why the CPU should stall when some I/O is ongoing. It is so frustrating to watch a CPU load of 20%, have two CPUs, and still have a machine that is so sluggish that it is practically unusable.
I'm a double idiot, because when my first MacBook Air broke (the common hinge problem) I bought a second generation one, thinking that Apple fixed the problems. To be sure I was not the cause, I did a clean install.
Now I sit here tilting my almost new MacBook Air to give free airflow under my machine by my table fan, and still can't really use more than one application at the time, constantly restarting web browsers to be able to scroll pages, exactly the same problems as the first one.....
I have hopes for Snow Leopard fixing part of my problems, the disk I/O problem, but who knows.
I do think I will buy a new copy of CoolBook, the tool that saved me with my first MacBook Air. If underclocking and undervolting, it was kind of usable, could even watch videos!!!
Apple, please, fix MacBook Air!!!!
