Macbook Air suffering loud fan, extremely slow
Hi,
I'm using a MBA Mid 2013 (warranty ended by June 31), and below is my story (verry sorry if it's long and waste your time).
By the third week of June, my MBA got a problem with the sound. Since it's still in warranty duration, so i took it to an Apple authorized service center in my place. They kept it for a week, and after that, my MBA's sound problem gone. But:
Actually, I made some quick tests in that center, and everything seems normal. So that, i closed my MBA and left the center.
When i got home, i opened my MBA to retouch some photos, but the MBA is extremely slow (opening a photo in Preview took around 1 min), and the fan went crazily loud.
I opened the Activity Monitor. Surprisingly, there's a process named kernel_task was taking ~300% of the CPU, thousands of the CPU time.
I did some research in the community, and found a solution: "Reset SMC". I tried that solution and magically, the problem has gone. So that, i thought it was just a software problem, instead of a hardware one.
The warranty expired...
The first half of July:
Everything seems OK and my MBA is stable.
The previous week:
The kernel_task error seems back. At first, i repeated the SMC reset solution and it still worked. But few times later, that solution turned useless.
Although my Mac was still usable, but during the kernel_task error, it's very slow that i could not do anything. Sometime, the kernel_task automatically turned normal (and my Mac is fast again).
At that time, i tried a list of other solutions and found something:
- Reset PRAM: The key combination was very hard to be succeed. Mostly, my MAC normally boot to the OS.
- Safe mode: Same.
- Recovery: Same.
- Apple Hardware Test: Same. But, in a success one, the result said that there is a problem with my thunderbolt (When i check in the System Information, the thunderbolt part said that No Hardware Found...??).
So, I guess that there's few problem with the OS.
So that, in the previous weekend, i tried to re-install the OS (Maverick). My Mac seems normal again.
But today, after a sleep - wake cycle (close, and open the Mac screen), the kernel_task disaster was back.
In this evening, i tried to re-install the OS once again, with a different installation. But... the problem seems more serious.
When i booted by a usb to install OS, the fan still loud and my mac still slow, which lead to the OS install could not be completed (stuck at 13%). And now, i almost cannot even choose the Startup Disk. Although i pushed and pressed the option key, my Mac will automatically boot to the Utilities for restoring the OS (because i formated that Mac partition).
Now, i'm very disappointed and confused. My mac is slow and the fan is loud anytime, i cannot install the OS. A software (perhaps?) error now turns to a hardware (perhaps?) error?
Could someone please tell me what is that error, and is there anyway to fix it?
Thank you in advance!
Well, when you use a secondary display you are making the graphics processor work harder. That would explain the fan noises. Also, be aware of where you place the comptuer. Try not to block the back so it can vent and not place it near other warm devices.

My Macbook Air has suddenly become extremely slow and is always crashing?
Hi, I would really appriciate some help right now.
I have had my Macbook Air for a little more than 2 years. It has always worked pretty well. However, recently I went on vacation for 1 week without my laptop. When I returned home and went to turn on my computer, I noticed that it had become extremely slow. Firstly, turning on my computer has become an abnormally long process. It used to take about 2-3 minutes to turn on. Now, it takes a solid 10 minutes. Not only this, but once my computer has finally turned in, it usually takes another 10 minutes before I can open an internet browser. When I click on the browser (I used Google Chrome) no window will pop up, and after a few more clicks, my screen will freeze completely. Sometimes I will get the rainbow wheel and sometimes the screen just completely freezes without it. Sometimes I will try closing the lid of my computer and then reopening it, but when I do this, the screen stays black for a long period of time even after I have reopened it, almost as if the computer is off. After an excessive amount of key smashing and an abnormally large amount of time, the screen will finally stop being in sleep mode and show my desktop. Even then, my computer will still barely work. Once I finally get a window open and start using the internet, google chrome will end up crashing within at least 20 minutes. The entire screen will freeze, I won't be able to scroll down or exit out of the window, and I then usually have to repeat the painful process that I described above when I attempt to open my broswer.
It has been over a week since I returned from vacation, and I deal with these issues every time. My computer has always been fine in the past, why is this suddenly happening?
I have tried to remove some of my applications my going into Finder and highlighting the application and clicking Move to Trash, and then emptying the trash. This hasn't helped at all. Do you think that it would help to delete some of my files and data (pictures, documents, screenshots, downloads, ect) or is this irrevevant?
I would really appricate some help! I am really sick of having to deal with this. I have no idea what is going on or how to fix it, or why this has suddenly happened after a week of being away from my computer.
Thank you so much. If you need any more detail or have any more questions, please ask.It's likely that the internal drive is failing, or you have some other hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the Lion recovery partition, if present. -
Macbook Air late 2008 running extremely slow
I just bought a Macbook Air late 2008 online & when i recieved it it had been wiped out and set back to it's original favroty settings. The battery is completely dead so it must be charged at all times. Everytime I use the laptop it is extremely slow & laggy. When opening apps, typing, watching videos, everything. I upgraded to the new Mavericks software available at apple.com hoping it would fix the problem but it didnt, & the laptop is still just as slow. Also everytime i turn the laptop on the date & time are set back to Jan 2008. I am a new mac user & I have no idea how to fix this problem.

Macbook Pro 2011 loud fans and slow computer functioning?
Today my Macbook has suddenly begun to act slow and the fans are running quite loud. I read online that I should try checking the activity moniter, and I did this, and a program is currently taking a large portion of my CPU. However, I am unable to quit it and I'm sure it is the problem. In one of the description fields it is lableled "root" and says "kernel_task". Someone please help me out!
Actually I'm still running snow leopard. But this problem is confusing me so badly. I have tried several times to totally restart the computer by holding down the power button for a few seconds. The MacBook restarts fine but upon startup the fans start running loud again and the Performance of the computer is clearly slower than normal. For example, when I maneuver with the trackpad down to the dock the icons are very slow to respond. Also, normally upon startup my keyboard illuminates upon viewing the log in screen, however for some reason this is not happening either.
I hope someone on here has the solution to this it would be greatly appreciated. -

What is your definition of "good for gaming?" I think that's the biggest problem with any machine that features an integrated chipset. If you're looking to get 60 FPS in an 8-on-8 game of Modern Warfare 2 at ultra graphics settings, that isn't going to happen. What sort of games do you play? What are you requirements/expectations. If the purposes for this machine exceed 50% "for gaming" you really need to consider the 15" MBP with a dedicated GPU, the differences are quite significant. -
I opened up my Macbook Air and my fan started running on high and stayed on... meanwhile it was lagging so bad all of a sudden that I can barely use it.. the mouse jumps and my programs won't open, like its backed up. I cleaned up my memory recently so I know it isn't backed up. The fan stays on high from the moment I open it to whenever I shut it down. It has never done this before, what could be the problem???
Thank you, but I followed all instructions to reset the SMC and it has not helped. Looks like I'll have to take it in to Apple for repair.

My macbook internet download speed is extremely slow. I have tried 2 other computers, another mac and windows and the download speed is over 10mb but with this macbook pro it is less than 1mb. What is causing this and how to fix?
To find out how much space you have & what is left, open up Disk Utility/Machintosh HD/First Aid. The info will be at the bottom of the window.
Sluggish Finder - Bunch of icons on your desktop? An overcrowded desktop slows down your Mac.
Get rid of needless Finder calculations - Open a window in Finder/View/Show View Options: ensure "Calculate All Sizes" option is unchecked.
Internet related - It's likely that your broadband connection is the bottleneck. You can check your speed on http://www.speedtest.net to see how fast your connection is. If your web browser specifically performs slowly, quit and relaunch it.
If browser remains sluggish, empty its cache.
Safari/Empty Cache
Firefox/Preferences - select the Network tab of the Advanced preferences and click the "Clear Now" button in the "Offline Storage" area.
Application related - Launch "Activity Monitor" - Applications/Utilities - click the CPU heading and see what float to the top. If an application takes up a large chunk of CPU and won't let it go, it could be dragging down your Mac's performance. Quit it by clicking the Quit Process button at the top of the Activity Monitor window.
Too little ram - max out your ram.

MacBook Air 2.0 Fan Noise While Idling
I picked up a 1.86, 128 SSD MacBook Air last Sunday and have run into an issue with the fan. At first, the computer was near silent as I've experienced with every Apple laptop I've used. However, while reinstalling OS X to trim the printer drivers and language translations the fans kicked on to full bore. After restoring my system with Time Machine, the fans now make a rattling/vibrating noise from the time I start the machine, or wake from sleep.
Since I didn't notice this at first, I'm guessing that I am experiencing an unfortunate defect with my machine. I was hoping to gauge those of you who have purchased this machine to see if this was an isolated case or if this is normal for the Air.
Also, the noise is not extremely loud, and isn't noticeable with a bit of ambient noise in the room like the TV or music. When it is just me and the computer it is quite distracting. Thanks for the help.unfortunately that's not a desired solution since I already own a MB Pro. The MBA should be the light OS X laptop to carry around. That's why we cope with the little number of ports and even with a battery that cannot be changed by own means.
Because of the poor graphics and the related processor work producing loud fan sounds by just watching a you tube video / a flash site or doing any other not really power intense stuff I sold my MBA rev1 and bought a rev2 to overcome the graphic card bottleneck and overcome this problem.
And that's where we are right know ... stuck with a better machine in terms of power but not in terms of the display.. left alone by Apple so far in the middle of nowhere with this issue so far. I even can't go to an Apple store and ask them to open any MBA and give me one with a perfect display. We ain't got an Apple store so far in Germany. It's thrid party electronics stores selling those products over here and they actually deny opening the devices before being sold and handing me over a perfect one. Despite of that I have to buy it and afterwards return it for "repair". That's "real customer service" with greated satisfaction. So the only way for me is to gamble and to order directly from Apple Store online and return it if it's not a perfect one. It did this twice but due to the forums experience and due to my personal experience I went for a refund after the second rev2 and now are waiting for a couple of weeks until I will give it a try again. But as long as Apple does not officially react I doubt much will change.
However compared to the number of posters and the sold devices the percentage of complaining users is so low (0.000.x %) Apple probably does not see a reason yet to react. The only thing that keeps me from thinking that it's minority problem is that so many people are reporting that so many MBA rev2 in Apple Store would show the problem to and that even the store genius and stuff admit the devices to have this "faulty" screen. That's my only hope in terms that maybe something in the future will change and that maybe there comes a day (hopefully in the near future) where I can go and buy and get a perfect MBA rev2 and thus an Apple Laptop that I can use what it was designed to be an "almost" perfect lightway OS X device. -
My Macbook air laptop sound, fan and speed is messed up, how do I fix it?
Where do I start. One random day I came home to find out that my sound has been muted. I tried to fix it with headphones, reseting the PRAM, google, and even by asking my schools computer tech. Some times the mute button would disappear and the sound bar would be in color but their would still be no sound. After the computer tech went on his account on the laptop to un-mute it, which he couldnt, he told me that my built in speakers dont work and would need to be replaced next year. Im like okay no problem, that same day i closed my laptop and found that the light was still on, I asked a friend and he said the black bar between the keypad and screen is what activates the laptop to shut off, which means its broken, so in between class periods i either shut down my laptop or put it to sleep. The next day my laptop starts to run slow and as soon as i power it on the fan runs immediately but the laptop isnt hot. My mouse moves at normal speed but my applications are running slow. This all happened in one week which is this week. My battery dies at a normal pace though.
More information
This is a school given macbook air for a magnet program called iPrep, so i cant download anything with our administration password
This is my second laptop out of the 3 years ive been in the program. My first laptop started to break after the sound got muted and my laptop ended up with an X on the battery and would only turn on when a charger is plug but would go super slow. This makes me scared cause i dont want that happening at all to this one.
Problems
Sound is muted, it sometimes un-mutes but there is still no sound, internal speakers broken
When closed the screen display is still open
Computer applications go slow, fan turns on immediately
Any help, this is bothering me so muchHi Jollified,
Does your sound work when you try to use head/earphones? If so, try the following:
Plug your Headphones into your Mac.
Play a sound through them (a song for example), then stop the sound.
Make sure 'Preferences' is isn't open. If it is, Quit.
Launch System Preferences > Sounds.
While the Sounds tab is open and set to 'Headphones', pull out the Headphones from the jack.
You should see your Mac reset to 'Internal Speakers'
Also, I see you have tried resetting the PRAM, have you tried resetting the System Management Controller (SMC)? Resetting the System Management Controller (SMC) on your Mac - Apple Support
As for your MacBook not sleeping when you close the lid, there are many reasons this can occur.
First of all, check out Apples article on the issue: OS X Yosemite: If your Mac won’t go to or stay in sleep If you find these steps don't help, try a few of the following:
A common cause for the Mac not sleeping is your printer. If there are queued jobs waiting to be printed, but your printer is switched off, for some reason you Mac just wont like it and simply will not go to sleep. System Preferences > Print and Scan > Open Print Queue
Do you have an Ethernet Cable connected? People have reported in the past that removing their Ethernet allowed their Mac to sleep. This goes for other things you may have connected directly to your Mac also.
Try heading into your Mac Preferences > Sharing and deselecting 'Internet Sharing' as well as 'Printer Sharing'.
Also deselect Wake For Network Access by heading to System Preferences > Energy Saver > Power Adapter > Wake For Network Access.
Energy Saver > Schedule > Startup or Wake - Uncheck.
Alternatively, set your system preferences to Never Sleep, and put into Sleep manually: System Preferences > Energy Saver > Computer Sleep > Never.
Good luck! -
Macbook Air (1st Generation) is crazy slow - running on 10.6.8
A friend just gave me his old macbook air (1st generation) to see if I can get it into working condition. It currently works and is running on 10.6.8, however it is EXTREMELY slow.. I am wondering if it is possible/recommended to revert to 10.5.6 - something I saw in another forum - but I'm not even sure how to do that. Anyways any simple tips (for a novice computer guy) would be much appreciated.
Thanks!You can also free up some RAM and make the performance better by deactivating the Dashboard. Open terminal, and do the following command:
defaults write com.apple.dashboard mcx-disabled -boolean YES
then do:
killall Dock
I'm not sure yet how to activate it. This command doesn't erase the dashboard but it deactivates it. Or, you can just instead of deactivating it, remove all open things on the dashboard, such as the calculator, the note thingie, the clock, etc. -
is it normal for my brand new macbook air to get really loud when I'm playing non-intensive games from the app store?
Yes that is normal.
“During processor intensive activities—such as processing HD video or playing a game that makes extensive use of the graphics processor—the fans speed up to provide additional airflow.”

My macbook pro (late 2011) is extreme slow, freezing, crashing and lagging too often.
I am new to the forum, I hope this is the good topic to post my problem.
I have a late 2011 Macbook Pro, and it is getting slower and slower. The performance was bad with Mavericks as well, but now, with Yosemite installed, it is much more worse. I have never reinstalled my system (only upgraded the osx), so it is an almost 3 years old setup. In that time I have installed a lot of applications, and also deleted a lot. About a year ago I upgraded the RAM, but didn't help too much. Now with Yosemite my startup time is more than 5 minutes, and sometimes the startup freezes (and I have to push the power button long to retry). Safari with 5-10 tabs is extreme slow, and lagging when I switch tabs or open new ones. To launch a new app, for example skype, i have to wait 1-2 minutes. Everything is slow. Sometimes my finder crashes, and works only if I restart the macbook. Another example: if I open the downloads folder in Finder, I have the spinning loading icon for about 20-30 seconds, and just after this time can I see the content of the folder.
My console is full of errors, I get new records in every single seconds. I repaired the disk permissions, deleted safari cache, history, etc. but nothing helped.
Many people here attached an "etrecheck" record for their threads, I downloaded the app, and made one scan, you can see my results here, I hope someone with more technical skills can help me!
Thank you in advance!
(and sorry for my english - it is not my mother language)

Dec 11, 2014, 12:04:08 PM Self test - passed1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
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. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
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. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. 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.
6. 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. Don't log in as root.
7. 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 the browser window, 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.
8. 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.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. 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 the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
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.
11. 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 what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

MacBook Air heats up quickly, is slow, freezes
Hi there.
My MBA has recently started acting up -- CPU gets pegged and fan spins up to max with seemingly no load. Freezes on occasion -- just basically sluggish and sickly performance. Report follows. Any advice would be very much appreciated:

Am unable connect a MacBook Air to Airport Extreme using a valid password get an error message that password is invalid. The Mac belongs to a visitor from Japan?
Test by simplifying the name for the wireless and set names for the two bands..
eg AE24ghz and AE5ghz.
Then use no security.. does the MBA and iphone then join..
If so put back security.. wpa2 with simple password, no spaces pure alphanumeric mixed case and numbers.
If no connection test with fixed channels .. say 11, 9, 6 in that order for 2.4ghz.
Don't worry about 5ghz for now.. if it still won't join it is somehow incompatible.. you need to reset the Japanese devices but I am not sure how. -
MacBook Air .. Fan CPU and youtube test @ Apple Store...
Folks,
Just spend 3 hours at Apple Store in London.
Speak to genius and start investigating the MBA..
We Open 5 Safari explorer tabs and on each tab you tube is running.
turn on the itunes playing movie in there in itunes.
surfing internet same time.. and leave it running for test 15 min
No core shutdown, well mba get hot but not burning hot and they advised its aluminum case and should feel hot ..so MBP as well.
fan rpm goes to 6200 and CPU temp goes to btw 60 to 78 Degree 'C'
remember 5 you tube video's running and itunes is playing movie and surfing internet
so hammering the MBA...
I said well can we do same test on MACBOOK PRO..
did and guess wat same results and CPU went up to 85 degree 'C' using i stat.
I was also offerd a new MBA at store replacement if i am not happy with mine.. but i decided not too.. coz after that test i feel my MBA is okay no core shutdown and nothing major sign for crash or anything.
if i replace i might get dodgy one.. never know..
so
I got back home running everything and no prob at so far..
Oh yes they rest something on my laptop by restart the MBA and press power button option and shift key together i dont know what that does but it does reset something after install the SDU or SUD driver or something.
so currently working on it and if anything goes wrong i got warranty so take it back any time
