Macbook air problem using airplane power

I was on a Continental 737 using my normal power adapter - when plugged in the track pad would not function properly. It would not respond to my touch. When I unplugged it, every thing was OK. Any one else have this problem?

I had the very same problem on one of my visits out of country and resting my palm on the palm rest when using the trackpad solved the problem.

Dlink - macbook air problem

I have bought a dlink router, at first there was no problem, but later on my macbook air started using up to 40 min. to find the router, now it can't find it at all. What can I do to make my air find the router? I have a another PC with windows 7 that finds it, also my phone has no problem finding it. What is wrong?

Hello,
the dlink routers normally cause no serious problems with MAC's. The problem may be located in the settings of MAC and/or Router. Eventually also the Router have only a "hickup".
First Aid
Switch OFF the wireless network on your MBAir
delete the (your) network from the "known networks" list in the System Settings of your MBAir
reboot
rejoin the wireless
You may eventually also reset (start over) your dlink while on ALL wireless units in the net the WiFi is switched OFF.
Give the router a few minutes to run up
Then reconnect all participants one by one. Reconnecting the next one not until the previous have a clear connection to the wireless.
If none of the above solves the problem or you have already tried that, it would be very helpful if you may provide us with some infornation about your infrastructure and settings either in the router and the MBAir.
e.g.
router type
used protocol(s) with the router in your wireless network
used security method
used band (2.4GHz, 5GHz or mixed mode)
eventually used "older" systems in your wireless that eventually need compatibility mode
wireless configuration of your MBAir
and so on. Whatever you think it could be a useful information.
This will be very helpful for us to help you on fixing your problems.

My MacBook Air, once pressed the power button, comes up with a file containing a question mark. I have tried re-starting it but this logo continues to appear and will not go. I cannot log onto my mac. Any suggestions as to what this is please?

You need to reinstall OS X:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Call the Airline and see if someone turned it in. That is about all you can do. There is no other way to track it. Also, read this: http://support.apple.com/kb/ht2526

What do you mean by "power surge alert"? What exactly does it say when you try to connect it? If you're talking about the message about a USB device drawing too much power, that can sometimes be caused by a bad cable or something stuck in the port. Do you have another cable you can try?

Start by doing an SMC reset http://support.apple.com/kb/HT3964 and see if that resolves it.

Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
If this does not help, contact Apple.
Best.

Migrated powerbook to new macbook air with mavericks and the macbook air is using much more storage

I migrated powerbook to new macbook air with mavericks and the macbook air is using much more storage than the powerbook.

I'm trying to figure out why the new macbook air takes almost twice as much storage as the old powerbook with the same content.

MacBook Air problems

I have a MacBook Air with Mountain Lion. I just noticed today that I'm not getting a start-up chime when I turn it on. Also, for a couple of weeks now the following has been happening intermittently: When I open the lid, sometimes I don't get a sign-in prompt and the screen is totally black. I close the lid and open it again, and the prompt appears. Also, sometimes I get a kind of 'ant races' screen (white), so again I close the lid and reopen it and it's ok. I'm worried that something is failing here. I should point out that I'm no expert in computers. I went online to research this and tried an SMC reset, but that didn't do any good. I had resinstalled the operating system a couple of days ago since it had been running really slow since I installed Mountain Lion, taking about a minute to power down. It used to immediately turn off when I hit the power button. I hope these descriptions are clear enough and would sure appreciate any help anyone can offer!

I did the pram reset and that seemed to solve the problem. However, this a.m. I started it up, no chime, and I was getting weird boxes dragging on the screen that I couldn't get rid of when I tried to log in. I closed the lid and it came back up normally. So I ddi another pram reset. I'm not sure what's going on here, but I'm afraid I have a bigger problem. Can anyone offer any input here?!

MacBook Air USB external drive power source

I have a LaCie 250GB USB external drive on my MacBook Air and the computer is not being able to power the drive without me connecting the hard drive to an external power source. when the drive was had about 80GB of data it would do it, now that the drive has about 180GB of data, it does not work. Can anybody recommend a solution or an external drive that can hold at least 250GB that can be powered by the MacBook Air without need for external power source?

I have the same time of problem. Although, it's mentioned a using a self powered hub. However, I find this did not work. Apple states that the single usb port on the MBA is high powered to give the ext. super drive they sell the power it needs to connect to the MBA. What I have noticed is no matter which USB self powered hub I use I get the same results. The MBA reports that one or more devices is drawing too much power. Although, the powered hub is supposed to provide power to those devices that require power over USB. I should also mention, all I am connecting are two USB devices. 1 ext. Verbatim 500 Gig Drive. and my iPhone. Since the MBA has only 120 gig drive I had to move all of my movies etc. to the Ext. 500 now if I want to sync my phone or move a movie to the phone I get the errors.

Beachball on boot with MacBook Air + kernel_task using 138% of CPU

My wife's MacBook Air has recently become unusable - when you boot, it seemingly operates fine until the Finder launches, at which point the beachball appears and persists indefinitely. No applications can be launched, files accessed, etc - the only think you can do is hard shutdown.
Booted in Safe Mode and set Activity Monitor to launch on startup, then restarted in normal - kernel_task is using 138% of the CPU consistently, beachball issue present.
Shut down and booted again in Safe Mode and the issue is not present, with kernel_task using an appropriate amount of memory. This is the wife's computer, I'm a PC guy, so I only know little bits of Mac stuff - repaired permissions, etc - to no results. Any ideas on how to move forward in resolving this?
Thanks in advance.

First, you might delete the /Home/Library/Preferences/com.apple.finder.plist file while in safe mode.
Then try this:
Delete caches to resolve some startup problems:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
/sbin/fsck -fy
If you receive a message that says "*** FILE SYSTEM WAS MODIFIED ***" then re-run the command until you receive a message that says "** The volume (nameofvolume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
If you were successful then enter:
/sbin/mount -uw /
rm -rf /System/Library/Caches/*
rm -rf /Library/Caches/*
reboot
I suggest you print out the above in a large mono-spaced font to be sure you do not make any errors when entering the commands. When in single-uwer mode you have 'root' access, so it's important that you not make any mistakes. Note that there are spaces between a command and what follows, so be sure you type each line above properly.

MacBook Air kernel_task using 130 to 150 % CPU overload with fan overheat

After hours and hours to get a diagnostic for this problem, I have solve it.
It seems to be a troubleshooting with the Apple ETHERNET to USB adapter used thru an USB Powered hub (A Kensington here)...
My configuration was:
MacBook Air 1.8Ghz SSD
Wireless BT Apple Keyboard (Aluminum) and Mouse
24" Apple Display (DVI)
USB USB Powered
iPod Classic 80 Go used by iTunes and Time Machine for Backups
__!! Apple Ethernet/USB Adapter !!__
Canon Pixma USB Printer
Overload CPU with kernel_task up to 150% was cycling.
That's the first reason of the difficulty to diagnose it.
Because the adapter was so hot I couldn't even touch it, I thought it was probably in charge of this mess.
Reading some forums, it's possible that there's multiple reasons for an overload CPU time by the kernel_task and this is one of these.
If you encounter messes with kernel_task using an Apple Ethernet/USB adapter, check it first to do anything else.
Hope to have help you...
Nick

it seems to be temperature issue, i.e. the system tries with the kernel task to avoid an overheating of the cpu/gpu. those guys here

Handsoff macbook air problem yosemite

hi, I have a macbook air 2011 and yosemite but the handsoff dont enable... I try ALL OF tips of the world but nothing.. why apple decide to dont support this mac?

Just to post an update: I noticed that if I reboot my Macbook with the HDMI plugged in, sound comes up normally. The problem starts to happen when I unplug the HDMI cable (i.e. to take my Macbook with me to work) and plug it back in. Anyways, I've been doing this ever since I bought this Mac and never had the issue when using Mavericks.
