MacBook Air is laggy and the fan is out of control

My MacBook Air 2013 is laggy and the fan is out of control. The fan is out of control even when I start my macbook up. I don't know if it has something to do with Yosemite or something else. I have tried SMC restarting, and nothing has changed. I would really love to hear if anyone else is having this problem, and I would love to hear if any of you have any tips. Also I checked if anything is using up my CPU a bunch, and nothing is out of the ordinary.

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.

Batteri is dead and the fan is out of control

My batteri isnt charging (its dead, can make it without AC for 3min) and after 2 min of using the computer the fan goes from 1500rpm to 6200rpm. Ist because the batteri isnt working as i should or is the problem something else that make the fan go out of control?

.. but without AC the computer work just for some minutes.
If i remove the AC-cable and then check the battery status, it look like this:
Batteri:

When I try to drag and drop to combine events in iPhoto, the drag accelerates out of control when it reaches the top or bottom of the screen. How can I slow it down?

Album overview
A photo album in iPhoto is just like one you would create with printed photos: It’s a collection of photos you select from your library and arrange in the order you want.
You can create photo albums to:
Focus on a particular subject, such as your favorite nature photos
Group pictures that you want to send to a friend, post on a webpage, or burn to a CD or DVD
Gather a decade of anniversary photos
iPhoto has two kinds of photo albums:
Standard photo albums: You create these albums (B, shown below) by selecting particular photos. You can add new photos by dragging them to the album (or using the Add To button), and you can remove photos at any time. All adding and removing is done manually; iPhoto doesn’t update standard albums automatically as you import new photos.
Smart Albums: iPhoto creates these albums for you, based on criteria your specify. iPhoto then updates Smart Albums (A, shown above) for you as your library changes. For example, you could create a Smart Album containing:
Photos of specific people, such as your family members. As you import new photos, iPhoto uses Faces to detect your family members, and automatically adds new photos of them to the Smart Album (after you’ve confirmed the matches in Faces).
All the photos of your daughter taken on school field trips in third grade. Use Faces (to name your daughter) and keywords (to mark certain photos or events as “field trips”) to help specify the photos you want iPhoto to place in that Smart Album.
Only photos taken with a specific camera, or photos matching other Exchangeable Image File (EXIF) information.
You can make as many albums as you like, and you can include the same photo in several albums without making multiple copies of it.
After you create an album, such as “Australia Adventures,” it appears in your Source list below Albums.
In full-screen view, the album appears as a stack of photos below Albums.
To further organize your library, you can group several albums (along with slideshows and projects) into a folder. For example, you could create a folder containing several years of birthday albums or a collection of albums with photos of your camping trips.
To create a folder, see “Create a folder in the Source list and move items into it” in “Customize the Source list”.
Folders appear only in the Source list, not in full-screen view.
Note: A photo album is different from a photo book, which is a collection of photos you create to get professionally printed and bound. See this topic: Photo book overview.

Where does the air from the fans come out?

I was wondering where the air from the fans in a 15" MacBook Pro come out. I know that the fans run all the time so I wanted to know where the air comes out so I know not to cover that part of the computer when it's running.

In the link I posted (actually from an Apple manual page): "Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents."
At:[http://www.resourcesforlife.com/docs/item3485] -- "The hot air exhaust is in the middle and on the right when looking at the back of the computer. "

24" iMac - noisy fan

Early 2009-model iMac 24" - previously fan was silent, replaced screen/HDD under Applecare and suddenly the fan is making a very obvious whirring noise which gets extremely high pitched at high fan speeds. Sent to AASP twice (two different stores), they say they can't hear it and will therefore do nothing- what can I do? This noise is driving me crazy, as I work in a silent room. SMC reset does nothing.

For the first one, they took it into their tech workshop and tried it - second one was in another country! Ambient temperatures are around the same too.
Fans make a noise from boot is the problem (even before the Apple logo appears) - temperature readings are normal, fan speed too (~ 38C/800rpm ODD). When I use SMCFanControl to increase fan speed, the noise increases proportionally - that's how I figured it was the fan (previously, I had no idea what was making the noise). Great idea though.
I only have access to one AASP in my city, and have to travel for 2-3 hours to get to my nearest Apple Store (and I don't drive...). I'm sure if I were there and *made* them hear it (ambient noise tends to eradicate any noise made by my iMac) I'd get my iMac back to its perfect state. Gah.

HELP. New IMAC loud fan

Just recieved my 2011 imac i7 with 16 Gb of memory running on Lion. The fan right out of the box , with only the apple software pre installed is extremely loud and runs constantly. What do you all recomend i do at this point? I will be utilising this for heavy duty graphics and motion.Very dissapointed.Should i cut my losses on this and return for a Mac Book pro instead as i am reading about a fan problem with these Imacs.
thanks-Kev

All the fans run constantly. But if the fans are very loud you should get the unit replaced while still within the 14 days from purchase.

IMac G5 fan always at maximum speed after booting into si...

IMac G5 fan always at maximum speed after booting into single-user mode in 10.4.3
Model: 1.6GHz iMac G5 with 10.4.3
I updated my iMac to 10.4.3, then booted into single-user mode to do some cleaning at the command-line level. I know, as others have discovered, that in single-user mode, the thermal control is off, so the fan gradually increases up to maximum speed and stays there until you reboot or go into multi-user mode. Well, I have never experienced this one before, and I'm freaking out about it... I went into single-user mood one reboot after upgrading to 10.4.3, and after all the println white text lines ended, the [1] fan shot up to maximum speed in 0.35 seconds (it sounded like a high-pitched DJ record scratch during the time interval), [2] the fan stayed at maximum speed when I left single-user mode, and [3] I cannot get the fan to slow itself! I rebooted, shut down, and even tried booting off the Tiger CD, but the instant I hit the power button to turn on the iMac, the fans blast up to maximum speed. They shut down when I put the iMac to Sleep, but then they blast up again in full when it wakes up. I checked my settings in the Energy Saver preference pane, and I have the performance set to "Reduced," which is the lowest possible.
I searched to see if anyone else had this problem or if the KBase had any info, but I didn't see any. I'm thinking about erasing and installing my stuff on the iMac, even though I just did that today.
Again, this maximum speed fan problem is freaking me out. It just started when I booted into single-user mode in OS X 10.4.3. I have booted into single-user mode before (10.4.2) and have not experienced this fan issue. I repeat, the fans blast up to maximum speed after pressing the power switch to turn on the computer, so they do not even wait for the Apple logo to show up on the screen before blasting away. How can I get these fans to not do this anymore?!

for the last few months my 20" 1.8GHz Imac has been very noisy - fans seem to run constantly and noisily. It might have been when updating to Tiger but I was never sure. Today, on the advice of a chat tech, I opened the case and reset the SMU to hopefully cure another problem. I noticed that all the air vents, intake and expel ones, were all quite heavily clogged up - not blocked but clogged with dust and fluff. I cleared it away mainly by blowing but also with a hand held hoover held close by. The exposed fan still as a lot of muck on it but greatly reduced and all the vents are completely clear. Having put everything back together again the iMac has been runnning quietly all day. May have been the SMU reset but equally might just be that the computer couldn'tdraw in cool air, circulate it or expel it properly and the fans had to work overtime to cope. Worth checking if you have noisy fans running at speed constantly.

The "Apple ID Password box along with the keyboard keeps popping up on my iPad and stays there. I have changed my email address on my iMac but my old one still remains on the iPad. Also changed password. Nothing works! I can't use the iPad like this!

The "apple ID Password" box along with the keyboard pops up when I turn the iPad on and it stays there. I have changed my email address on my iMac and also changed my password. The old email address is still on the iPad. Anyway, I can't use the iPad because can't get the apple id password box to go away. Thanks for any help!

This is an older photo but the sleep and home buttons are still in the same place on all iPads. The home button is the round button at the bottom of the iPad and the sleep button is also called the on/off button and it is at the top right corner of the iPad.

On a new imac how much of the HDD is already used with the OS,iLife,apps..

Looking to buy my 1st ever iMac, the one Im going to get is the base one, with 250Gb HDD (I may upgrade to 320Gb for UK £29 though)
My question is how much of the HDD is already used by OS X and everything on it? I understand there is some free trial stuff onthat can be installed eg MS Office, iWork etc I would want these removed as wouldnt want them so how much is left before you start adding your own stuff
I also want to install Win XP on it so need to know what to do, 250Gb in todays computing is very stingy I think, so I need an idea
cheers

Here's are some disk usage information from my 20" white C2D. The numbers
are running totals that include periodic software updates and some of my own
stuff -- but that would be less than 0.5 GB of the final total.
OS-X with "no optional packages" is a very usable system; it includes 'core'
applications such as Safari, iTunes, Quicktime. It does not include any of the
iLife apps or the iWork/MS_Office test-drive bloatwares.
The large increase in disk usage for a minimum Leopard system is partly due
to the inclusion of more apps in the 'core' OS package. Some things that were
optional in Tiger have become part of the "minimum" Leopard install.
The Xcode software development tools are a standard part of every OS-X
distribution, but since most customers have no use for them, they're not
included in the factory-installed disk image. If you don't plan to install
them, subtract 3.4 GB from the final tally.
Factory pre-installed Tiger 10.4.8 & bundled software .................. 16.4 GB
Erase & Install Tiger 10.4.8 with NO optional packages .................. 2.9 GB
SoftwareUpdate to 10.4.10, with NO optional packages .................. 3.1 GB
Erase & Install Leopard 10.5.0 with NO optional packages ............... 6.6 GB
SoftwareUpdate (11/11, immediately after Leopard install) ............. 6.7 GB
Install Xcode SW development tools from Leopard DVD ................. 10.1 GB
Install & SoftwareUpdate iLife'08 (except iWeb & GarageBand) ....... 12.3 GB
SoftwareUpdate to Leopard 10.5.1.................................................. 12.5 GB
IMO, 250 GB is FAR more than you'll ever need for installable software plus
a sizeable collection of music/photos. OTOH, no amount of disk space will
ever be enough for an avid music/photo/video junkie, and everyone should
have an external backup drive. So, stick with the standard internal drive and
buy more external storage.
...a billion here, a billion there -- and pretty soon you're talkin' 'bout alot of money,

Setup Assistant and Migration Assistant do not restore MS Windows, it only does the OS X partition. All of your Windows stuff must be backed up and restore using a MS Windows application. If no one on this forum is able to answer your question then I'd repost it on a Parallels forum to see how other Windows users approach this.

Welcome to Apple Support Communities
The hard drive is not formatted, and it must be formatted in "Mac OS Extended (Journaled)" in order to install OS X.
Close the OS X installer, and go to Utilities menu (on the menu bar) > Disk Utility. Then, format your hard drive in "Mac OS Extended (Journaled)" as Format > http://pondini.org/OSX/DU1.html Finally, close Disk Utility and install OS X

Change from HDD to SSD

Hello, I have an iMac mid 2011 with a 2TB HDD, Although I know it is possible to change out the hard drive, If I wanted to change to an SSD is there any paticular brand or method I have to use to avoid the temperture sensor problem I have heard about with these models? (The fans start spinning at full speed with hard drive change out)
Thanks.

Instead of changng and losing all of that storage why not just add in the ssd?
