Why my mac book air warms up more and more often, more and more hot

Why my mac book air warms up more and more often,and more and more hot

I have this problem too when I use heavy applications like big intense games. When you use this, a lot of memory and CPU space is taken up. This causes the fan to spaz out. The fan tries to cool it off, which in turn makes an awkward loud noise. If it makes noise/and/or gets loud, go to "Activity Moniter" and see if anything is taking up a large amount of CPU %. If anything is 30%-70%, that a lot. Earlier, I transfered 2,400 pictures from my iPod to my Air, and it went crazy. Within like 3 minutes of it transferring, it got hot. I looked at the CPU %, and it was anywhere from 80%-somehow like 230%. Anything like games or apps or a lot of internet browsers can warm it up. One other huge thing that can cause this is airflow. If you operate it on like a pillow or something soft and/or somewhere with low airflow/circulation, your computer will get hot. So, either use it in your lap or on something like a table, and try not to overwork the computer. If neither of these things help, bring it in to the Apple store. I hope this helped! Good luck!

My mac book air can't start installation, because i use windows installation in DOS to make partion, now no mac os on it. How to get back the mac os? i have a window based iso image from a friend, because in my country there is no Apple service.

It sounds like you destroyed your boot partition and the recovery partition. Depending on it's age, your MacBook Air might be able to do a net boot. Plug and ethernet connection into it and attempt to boot. If it has the right firmware, it will find a net boot configuration on the net and boot that. Then it will give you a Recovery Partition like display and allow you to reinstall the OS X version that came with it.... assuming that it was Lion or ML. If your computer came with Snow Leopard, then even the net boot won't work.
At that point you need a bootable USB Key, or an external DVD drive AND a Snow Leopard installation DVD.
An Apple Store, if there is one nearby, MAY be able to get you going again. However, whatever is on the SSD now will be toast too.

Why my Mac book air doesn't charge straight away

Hi there, Are any people know why is my Mac book air doesn't charge straight away? Thanks!

Can you clarify that?
I mean, I think it quite normal for the computer to take a second or two before charging begins. It could be the SMC making a determination whether charging is necessary, such that overcharging or "topping off" does not occur.
You should also know that if your battery is already at 95% or higher when you connect the charging adapter, the battery will not charge further. The battery must dip below 95%, for it to begin. This is to prevent "topping off", to minimize cycling, which is detrimental to battery longevity.

HT1338 I dont have a mac book air can you install apps like (angry birds, temple run)

I dont have a mac book air. Can you install apps like angry birds and temple run?

Can you install them on what? Those are both iOS apps (meaning they can be installed on iPods, iPhones and iPads), but iOS apps cannot be run on either a Mac or a PC. I believe that there is a Mac version of Angry Birds as well, which is completely separate from the iOS version of Angry Birds.

My Mac book air will not turn on

My Mac book air will not start. No fan, no noise at all.

Start by working through the troubleshooting tips in: http://support.apple.com/kb/TS1367 and see if you can startup.

New mac book air CAN NOT install win7 ?!

I just bought new mac book air (1.4GHz dual-core Intel Core i5 )
Try to install win7, when go to win7 installation interface, the mouse and touch pad doesn’t work. ( I did try USB mouse, same).
BUT
I use same usb on my old mac book air ( 1.3GHz ) it works fine.
I called apple, a very nice lady tell me i should call Microsoft, because if mouse and keyboard works fine in MAC system that means the hardware is fine.
Is somebody have some idea about this ?
Thanks a lot !!!

If this is a 2nd hand Mac, some of those apps were free to the original purchaser, the Apple ID you saw, but they are paid apps for you.

I have accidentaly droped my mac book air. when i turned it on it keeps on freezing can someone help me?

i had just started using mac and i dont know what to do.

Well, since you dropped it, this problem is not covered by Apple's limited warranty. You should take it in for service and have a professional look at it. We have no idea what kind of damage was done to it when it was dropped.

I've noticed my mac book air charger has turned yellow and the rubber keeping the wires hidden is ripping, will apple care cover for a new one?

i don't ever move my charger from behind my desk and i have no clue what to do, i don't know what is causing the yellowing. i went to the mac store in my town and they said they couldn't replace it because of he discoloration but the apple store might because the are more lenient but i don't want to be charged when it wasn't my fault at all. I’ve barely had it for a year i really can't afford to buy a new charger so i don't want to be charged if apple doesn't accept it.

azuniga127:
Wires and their cover discoloring/fraying in one year? Sounds like a dangerous product problem to me.
If it were mine I would be calling here: https://www.apple.com/contact/
In there you will find phone numbers:
U.S. iPod, Mac and iPad technical support:
(800) APL-CARE (800-275-2273)
Tell them your problem with your computer as well as with the Apple service centers.....and if they put you off ask to speak to supervisors.
I have had laptops for years, since they came out, and I have never had to replacea a power plug except once when the plug-in bent out. No way I could prove or show that was normal wear. But I tried.
Be nice but firm with whomever you talk with. I think you have good reason to expect a no cost replacement under Applecare.

Mac book air won't turn on after shutting down unexpectedly

I was surfing the internet, when it all of a sudden went black and shut off. No warnings or anything.
The light on the charger no longer lights up. I have tried all the tips on apple website and nothing works.
Any suggestions?

Try resetting your SMC.
Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own
Note: This will not delete any data.
The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
I hope I helped.

Since yesterday my Mac Book Air can not find audio output device anymore

My MBA is now 13 months old. Apple wants to charge me $170 to fix a defect that has over 50,000 users asking Why?
I have read the cable is the problem and have ordered a $29.00 cable to repair the issue. But why would Apple want users to suffer and risk the integrity of the MBA? Why not offer to fix the defect and keep customers happy? Or is this planned obsolescence? I for one am not a happy apple customer.

I could not worry about how long it would take the 5th Ave apple store to fix the defective cable. I spend $29.99 and $19.99 for shipping and replaced the cable. It WORKS. Changing the flex cable was medium hard and I was not sure I got it right until the sound came back.
WHat a shame Apple would not fix this issue. next machine I buy I am getting the apple care extension.

Do you have a spare usb keyboard? if so, use it until you can take the computer to the Apple store to have it fixed.
Best.
