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.

  • Macbook Air 11" (Mid 2013) takes time to become active after being inactive for a while

    I've got Macbook Air 11" (Mid 2013). But it has an issue of taking up some time to be active after it has been inactive for a while (like when i dont use it for a while the macbook autosleeps and then when i want to work on it and try to get it active the screen only shows mouse pointer in a black screen and then the other components like the small window where you enter password and other takes time to appear...)
    plz help...I've been facing this problem for 2 weeks now...and wanna fix it as soon as possible....plz help...

  • Can I use my Macbook Air 13" mid 2013 with plugging charger even at 100 % battery full charge?

    I can't decide whether using My Macbook Air 13" mid 2013 with charging power adapter connected even though it is fully charged Or using Macbook Air with unplugging charger after fully charged. Please advice me to maintain my Macbook's battery at good condition.

    It will not hurt it as long as you do not leave it on the charger for an extensive period of time (say, days).

    What is "Other" and What Can I Do About It?
    see here:
    Your Solid State Drive and having enough space inside your Macbook Air & Pro
    Solid State Drive usage premise, or the “more space / upgrade SSD” question
    There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
    In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
    Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
    Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
    Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
    The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
    All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
    Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
    You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
    However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
    A Professional Example
    In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace. 
    You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
    Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
    Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
    Slim USB3 1TB external hard drive
    External Hard Drives
    External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
    1. Data backup and protection.
    2. Redundancy for important data.
    3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
    While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
    There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
    External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

  • Macbook Air 11" mid 2013 battery

    My macbook air 11" mid 2013 serial # C02KTARJF5N8 is showing only 4:30 hrs on the battery meter at the top on a full charge and is advertized to last for 9 hr

    I would suggest going into the apple logo, selecting about this mac, more info, then system rpoert, from there you will see power. Click on this and It will show a charge remaining and cycle count, ring apple with this info and they will tell you if theres a problem straight away. It will alsow show the condition and you will find out more info there. Also if your running RAM heavy apps this will effect battery life, but if theres a fault you will see it there. Any issues ring apple and they will tell you if theres an issue hope this helps

  • MacBook Pro Kernel_Task over 300% ; laptop running very slow

    My new (4 week old) MacBook Pro suddenly this weekend started running very slow with the fan running constantly. I found the "kernel_task" was running the CPU over 300%. I tried various methods mentioned in different threads but nothing worked. I eventually went all the way to wiping the disk and reinstalling the OS. This has NOT fixed the problem. I do not know where to go next. I am posting a copy of the EtreCheck report I ran, and I am looking for any help.
    The next step is taking this thing back to the Apple store. I love my MacBook, but not when it is not lagging like something running Windows ME. I expected more out of this machine than this.

  • 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.

  • My Macbook Air 11" (mid 2013 upgraded with Yosemite 10.10.1) freezes at 30% or 50% when booting.

    I have tried SMC and PRAM resets at boot up but still have the problem.
    I can start in safe mode OK.
    Any ideas welcome.
    Thanks

  • MacBook Air 13" Mid 2013 Display go Blank

    I have set my MacBook Air Energy Saver setting to its default settings...
    When its go on standby mode then i click/swipe on trackpad immidiately , Display going blank but keyboard Is working.
    And if i wait 10 to 15 sec after standby then there is no issue.
    Please Advice me how to fix it

    If you take a look at these (very lengthy) threads, you will see this is a widely reported problem, for which Apple have yet to produce a solution.  It is said that they are working on a firmware update that will address it but this has been talked about for a long time and still no update.
    https://discussions.apple.com/thread/5118135?start=0&tstart=0
    https://discussions.apple.com/thread/5475679?start=0&tstart=0
    https://discussions.apple.com/thread/5495588?start=0&tstart=0
    The current "solution" (which is not a solution) given by Apple is to set sleep mode to 'never', or to wait a few secconds after sleep before waking the MBA, or install the free App 'Caffeine" which allows you to manually activate sleep and wake.
    Some persons have claimed a "bare metal restore" of the operating system resolved the problem but others have tried this without success.

  • Why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?, why does safari is very slow on MacBook Air?

    Hello. I am using MacBook Air. Safari is very slow and it doesn't open many websites. for instance: dizi-mag.com . please help me

    Please answer as many of the following questions as you can. You may already have answered some of them.
    1. Have you restarted your router and broadband modem since you first noticed the problem? If the answer is no, do that now and see whether there's any change.
    2. Are any other web browsers installed, and are they also slow?
    3. What about other Internet applications, such as iTunes and the App Store?
    4. Are there any other devices on the same network that can browse the Web, and are they also slow?
    5. If you can test Safari on another network, is it slow there too?
    6. If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

  • Macbook Air 11'' (mid 2013) My display isn't running as smooth as it was before, especially when using multi-gesture commands

    Hello, the major issue is that when I use a multi-gesture command like 2 finger swipe to check out my notifications or when I use 4 finger swipe to switch between apps, the edges of the app or window kind of get cut. Ignore the ghost effect in the picture. That's just because of the camera. Anyway, so you see that some widgets and the window on the right are like cut. Also when I do 4 finger swipe up or down, the windows don't move smooth at all. It looks more like a horribly done stop motion movie. An other thing is that when I hover over the dock, the magnifying effect vibrates for an instant before it fully magnifies and also when I'm hovering away it vibrates before it returns to its normal size. Also when I move the cursor quickly from one side to an other within the dock, sometimes the dock also gets cut. I started to notice these issues a little while after the update for issues with WiFi and Photoshop, maybe it has something to do with that. Any help is welcome.

    Reset PRAM.  http://support.apple.com/kb/PH4405
    If this does not help, contact Apple.
    Best.

  • Late 2013 iMac running very slow

    EVERYTHING is running slow.  My iphoto screensaver keeps freezing, all apps open super slow (wheel spins and spins) and iCal is not syncing properly with google calendar anymore.  I'm not sure what happened in the past few weeks but it has gotten bad!  My computer is only a couple months old.  I ran etrecheck in hopes someone can tell me what's going on.  I also ran disc utility and it found nothing wrong with my hard drive.  I'm running 10.9.1, 2,7 GHz Intel Core i5, 8GB memory. 
    Thanks in advance!!  If all else fails I will head to the nearest Genius Bar.

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
    Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking  anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal 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 Terminal in the icon grid.
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
    exec sh
    in the window and press return. You should then get a new line ending in a dollar sign.
    Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
    If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.

  • 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

  • Macbook air 2014 is 2013 mid?

    I bought macbook air in russian apple online store 1 month ago. Now I open settings and see that macbook air is mid 2013...
    Why is that?
    Is it normal?
    < Personal Infromation Edited By Host  >

    Weird - I thought I posted an answer to this already. The i7 model wasn't updated, just the core i5 model so it is indeed a mid 2013 computer.
    It's a bad idea to include personal information - like a computer serial number - in your post. I've asked a moderator to edit the post to remove it.
