MacBook Air late 2010 very hot after installing Mountain Lion? Can i back to Lion?

My MacBook Air, late 2010, is very hot and the vans are going too speedy after installing Mountain Lion. Can I deinstalling Mountain Lion and returno to Lion? What are the steps for this deinstallation? Thank you.

Technically, there is a way, but it is definitely not something I would recommend, as downgrading isn't usually supported/encouraged.
I found a website that has instructions but it clearly states it's not for the inexpert, so proceed at your own risk. Also, I don't think you can download Lion from the AppStore anymore?

Macbook Air Late 2010 display flickers after installing Yosemite

Hi !
I'm from Germany.
i have upgraded my Macbook Air, Late 2010 from Mountain Lion to Yosemite last Saturday.
The Installation works fine. At the first Time i have no problems, but:
One Day later i start my Macbook Air normally. Now the left side of the screen is flickering.
There are vertical lines to see. The right side of the integrated screen is ok.
i have resetted the SMC and the Power Management.
Please help, what can i do ?
Greetings
iRoGo

I noticed a similar issue with my MBA 2012 after installing Yosemite. The screen flickers slightly most of the time now. It's more noticeable with dark backgrounds. It almost 'vibrates' and is very annoying. Reminds me of an old monitor with a low refresh rate. I reset the SMC, PRAM, etc. and contacted Apple, who had me go through the same steps. The flickering is still present when booted into Recovery Mode. When I boot into Safe Mode the issue gets dramatically worse and I see screen artifacts like iRoGo describes -- parts of the screen blanking out, whole screen/parts of the screen flickering on and off, lines appearing, etc. It's basically unusable in Safe Mode.
At this point the issue seems to be hardware-related (i.e. issue persists in even in Recovery Mode), but I'm suspicious seeing that it manifested right after installing Yosemite. I will be bringing my MBA to Apple for service later this week...

Blinking cursor when installing Windows 7 on a MacBook Air (Late 2010)

Hi.
After spending several days trying to solve this, I turn to this forum.
I have a MacBook Pro Retina (Mid 2012) and I had no problem installing W7 on that machine.
My wife has a MacBook Air (Late 2010), on which I am trying to do the same.
I use an external LaCie BD/DVD reader/writer, which I also used for the MBP without problems.
After partitioning and restarting, the install DVD doesn't seem to want to work with the MBA, though. Only a blinking cursor appears. Occationally some message like "Error code 5" or BOOTMGR image is corrupt. The system cannot boot."
I've tried starting with Alt, and when the screen appears where I can choose the Install DVD, there is no HD image, as on the MBP in the same situation, but just an image of a disk under which is written "EFI boot" - and it keeps poofing, appearing, poofing appearing. Actually, the first of these poofing images is actually called Windows, but choosing this returns the same blinking cursor.
I have tried resetting the PRAM and SMC, as well as repairing the disk.
Any ideas how to solve this?
Best,
Richard

Can I install Window 7 Professional on a boot camp partition on my 1.8/2GB/64GB SSD MBA?
Today I installed Win7 Preimum on my brand new MBA (1.8/4GB/128GB SSD). I started with a stock MBA and first installed the new version of Parallels (7). After that installation, I installed Win7 Premium, followed by MS Office for Students and MS Streets and Trips. I should note that I also added slightly over 500 tunes for iTunes.
I was hoping to only install Excel and Word, but I never saw an option to go custom and as a result, all of Office for Students got installed.
With Parallels I didn't have to partition the hard drive. While I'm not totally sure, I think Parallels "grabs" empty space as needed, either for OS-X or Windows.
When I finished the installation, the computer reports that I still have 87GB.
I would assume if you went the route above and installed all the same programs, you would end up with 43GB of free space.
I intend to use my MBA as a road warrior, mainly surfing with some light Excel/Word. Unless you really need the Professional version, you might consider just installing the Premium version if the size of the program is much larger.
I've only been running for a few hours, but the machine seems very robust in both OS-X and Win7. Re the size of your hard drive, you might consider picking up a small external hard drive. I have a Western Digital Passport that is about the size of a cigarette pack and has the look of something that Apple might have made. 500GB for about $70.
I'm wondering if your 2GB of RAM might be a little on the weak side for going this route?

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

I get the impression that most of the users on older hardware experiences similar temperature issues on Lion for a long time now. Awaiting for confirmation from the original poster.
In the meantime I'm just cautious with regards to pushing the machine to such extreme temps, since something tells me such behaviour which includes monitor flickering and the likes is nothing but abnormal for any type of use...
Any clues if 10.7.5 does anything on this? If not I'm afraid i see myself going back to SL for good...

I have macbook air late 2010 model... it works fine otherwise but it has started being overheated in normal situations where normally it used to work fine and draining more battery....... battery time is almost half now.
should i reset SMC... would it help?

I'm doubtful it's a missing driver too, but I feel as though it's driver related. The first time XP was installed, after first boot without installing drivers, it was without sound etc, but fundamentally the system worked. Now after first boot, it's very buggy. Thanks for your suggestion Tonny. I ran the tool but it turns out the HDD is fine. Besides, everything runs fine in safe mode.
Does anyone know if (generally speaking) there is any firmware on the graphics card that would get updated via a Windows update? i.e. is it possible that Windows update downloaded a driver for the graphics card that installed new firmware that wasn't all that compatable with XP?

HOWTO: Make Virtual WiFi work in Windows 7 for MacBook Air (Late 2010)

I just spent several hours figuring out what is a bug in the Broadcom WiFi drivers for my new MacBook Air, and thought I would post how I fixed it for others until Apple can get Broadcom to fix their drivers.
Virtual WiFi:
First, what is Virtual WiFi. Virtual WiFi is a feature in Windows 7 that allows a single WiFi adapter in a computer to look like more than one adapter. The most common use for this is for software like Connectify that allows you to use your laptop as a wireless access point (AP) when you travel. For example, you might settle into a hotel room, pay for an Internet connection for your MacBook, and then want to share that connection with your iPhone, iPad, and other devices. For Virtual WiFi to work, the WiFi drivers for your WiFi hardware need to indicate that they support the feature, and then in Device Manager in Windows Control Panel, under Network Adapters you will see the "Microsoft Virtual WiFi Miniport Adapter" listed. Notably, this adapter was missing after installing Windows 7 and BootCamp 3.1 on my MacBook Air (Late 2010).
Why it Doesn't Work:
The strange thing is, this was working fine on my wife's MacBook from 2008, with similar Broadcom WiFi hardware. It turns out that whoever made the Broadcom driver file made a small copy-and-paste error, and neglected to support Virtual WiFi for the slightly different chip that is in the MacBook Air versus the MacBook. By fixing the driver file, the issue can be fixed. The problem is right here in the file, which we'll get to more below:
%BCM430N_DeviceDesc% = BCM43XNM_NT61, PCI\VEN14E4&DEV432b
%BCM430N_DeviceDesc% = BCM43XNG_NT61, PCI\VEN14E4&DEV432c
%BCM430N_DeviceDesc% = BCM43XNM_NT60, PCI\VEN14E4&DEV4353
My wife's MacBook uses the first line with DEV_432b at the end. Note that it uses the installation section BCM43XNM_NT61 which refers to Windows 7 and correctly installs Virtual WiFi. The newest MacBook Air uses the last line with DEV_4353 at the end (a slightly different chip). Note that it incorrectly refers to the installation section BCM43XNM_NT60, which is Windows Vista with no support for Virtual WiFi.
How to Fix It:
1) You first need to extract the Broadcom drivers that are in the latest version of BootCamp so that you can modify the INF file. To do this, I followed all of the instructions in the BootCamp Assistant from Mac OS X on my MacBook Air to download the WindowsSupport folder with BootCamp drivers, which you can save to the hard drive or burn to a CD. Once you have this, open the folder "Boot Camp\Drivers\Broadcom". We need to extract the file BroadcomNetworkAdapterWin7_32.exe or BroadcomNetworkAdapterWin7_64.exe depending on whether you are using a 32-bit or 64-bit version of Windows 7. I was able to do this with WinRAR installed, by right-clicking and selecting to extract the file to a folder.
2) In the folder from the last step, there are 31 files on my installation, but the one we want is bcmwl6.inf. If you open that file the first two sections (BROADCOM.NTamd64.6.1 and BROADCOM.NTx86.6.1) are the ones with the error as reproduced above. The first section is for 64-bit installations, and the second section is for 32-bit installations.
3) Modify the last line of each section to change BCM43XNM_NT60 to BCM43XNM_NT61, and save the file.
4) Now we need to install the driver from this folder onto the MacBook Air. I did this by opening Device Manager from Control Panel, right-clicking the "Broadcom 802.11n Network Adapter" under Network Adapters, and selecting "Uninstall" followed by "Update Driver Software". Point the update dialog to the folder where you modified the driver, and let it install.
5) Note that because the INF file is modified the driver is no longer correctly signed. You will see a warning to this effect, and you should select to install the driver anyway.
6) You should now see the "Microsoft Virtual WiFi Miniport Adapter" in Device Manager, and software like Connectify should work to share your WiFi connection.
Hopefully Apple will fix this the correct way soon, by getting Broadcom to fix their driver and updating BootCamp to include it. At the time of this writing, the Broadcom driver version is 5.100.57.8 so anything later than that may be fixed.
Good Luck!

That is one heck of a post for a newcomer here. Your instructions worked like a charm, with one exception:
When uninstalling the Broadcom Device, I had to check the box to delete the driver, and then had to scan for new hardware to get the device to show back up. Then I was able to load the edited driver software.
I am not complaining, but very grateful, as I was pulling my hair out on this one.

Help, how to downgrade my macbook air late 2010 from os x yosemite to snow leopard

A very good friend just updated my Macbook Air late 2010 (OS Snow Leopard) to OS X Yosemite. Now my Macbook air is messed up. No sound. Left shift key not working.and so forth. I am wondering if I can return it back to my previous OS?
How to return it to my previous OS? Please help me. No need to back up anything, as everything is in my dropbox.

1. 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.
Select Disk Utility from the main menu. Click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. When formatting finishes quit DU. Select Reinstall Lion from the main menu and click on the Continue button.

Repeating Console Message 10.6.5 on MacBook Air (Late 2010)

I just finished setting up the system on a new MacBook Air (13" 1.83ghz). I'm getting the following console message that repeats every 10 seconds. How can I stop it? Thanks.

My parents new 13'' MacBook Air (late 2010) would not fall asleep. After resetting the SMC to no avail I checked the console and saw the exact same message. After deleting the plist and rebooting the machine it is falling asleep now.
I never installed any third-party program relating to the battery and there is a folder called /usr/local however there is no sub-folder libexec nor did a "locate" in Terminal find the daemon batteryd.
Came across a similar thread on the Japanese Apple discussion forum (clicky). Since I cannot read Japanese I can only guess at what the various posts say. There seems to be talk about it being an Apple software related issue specifically regarding the HAL.
I checked on my MacBook Pro (mid 2010) and there is no such plist. Will check another 13'' MacBook Air when I get the chance.
If you delete the file com.apple.batteryd.plist in the folder /System/Library/LaunchDaemons and reboot the machine the message in the console will go away.

Face time not verifying apple id on macbook air late 2010....HELP please...!!!

hi i am juraij.....i hv macbook air late 2010 11.6inch and i have been trying to set up my apple id for FaceTime but every time i put in my id and password and sign in it shows my other associated apple id and ask to mark the one that i want to link with FaceTime .....after doing so it says to verify and when i verify..it take some time about 5-10 seconds and then take me again to the very first page i.e., it asks again for apple id and password and it continues...and also face time preferences is GREYED OUT.....PLZ help......

Did you ever verify the primary email address associated with the ID you are trying to use with FaceTime? If you aren't sure, go to https://appleid.apple.com, click Manage your Apple ID, sign in with the ID you are trying to use with FaceTime, then see if it says Verified under Primary Email Address (see image below). If it doesn't, click "Resend" to resend the verification email. Then check the email address for an email from Apple (be sure to check both the inbox as well as the spam/junk folder).

MacBook Air Late 2010 and Apple Hardware Test

I just bought a second hand MacBook Air Late 2010, 13 inches, 2.13 Core 2Duo. Everything works great, system re-installed after erasing the HD ( Mountain Lion) Internet recovery works great, all is ok.
The only thing that I can't work out how to get is AHT. I tried holding down D at the start but nothing. Holdind down D and Alt takes me to the Internet Recovery harware test, but when I try to run it, it comes out that the machine is not supported. I read that to be able to use it, I needed to dowload a firmware update. And so I did. But when I tried to install it it came out that it was not going to work on my system ( bare in mind that I can access and use Internet Recovery)
What Am I doing wrong?
I'm not too bothered about being able to use AHT at the moment, but there will be time when I will need to.
All the help will be appreciated.

It has to be available. It is the only way to restore that system back to as shipped from factory specs and reinstall the ilife apps. In your situation since you have another mac and a valid license for mountain lion and you have a air of a newer model year that can use the internet recovery system you were able to install a version of os x. But if you didn't have a license and that air was just one revision prior to that model year you would be stuck with a computer and no working os on it or no valid os on it.
Basically when anyone is selling an mac computer that computer should be wiped and the original os x version reinstalled. To do that on system older then late 2011, or some of the early 2011 models, you need the original apple supplied reinstall media. Whether that is dvds or a usb thumb drive. Otherwise the seller is selling pirated software and the buyer has no way of updating or upgrading that mac computer.

Since upgrading to ML, the trackpad handwriting function doesn't work on my macbook air late 2010

Hi All,
I've run into an interesting problem lately. I have several macs in my home and two in particular (the imac and mba) that my parents use had Chinese Handwriting enabled via trackpad. However, since upgrading to Mountain Lion from Lion, those macs have an issue with enabling the Trackpad Handwriting option.
First off, I started to troubleshoot the issue with the iMac. After some fiddling around by turning the function on/off it seems to be fixed. I then went ahead and attempted to perform the same "fiddling" and steps on my macbook air (late 2010), and it just doesnt seem to work. The funny thing is, if I try enable it with the keyboard shortcut, the system seems to acknowledge the shortcut and displays an option in the menu bar to hide the trackpad as shown in the picture. But there's no Trackpad Handwriting to to be seen on the screen. I've even tried resetting the PRAM and SMC with no success. Any solutions?

Try swiping down with two fingers. This solved my problem.

My macbook pro is very slow after installing mountain lion

my macbook pro is very slow after installing mountain lion? Is anyone else having this issue?

If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

My Macbook air (late 2010) shuts down randomly!!

Need some help here!! My Macbook air (late 2010) shuts down randomly, sometimes it won't even power on. This happened to me one morning, then at night try turning it back on, it went back to normal, I didnt do anything to it. Today it did it again but it went back to normal few minutes later after hitting the power buttom more than 10 times

Hi Argenisss,
I'm sorry you are having issues with your Macbook Air. Since your post indicates you have the latest version of the operating system, I would suggest resetting the System Management Controller (SMC)
Intel-based Macs: Resetting the System Management Controller (SMC)
Power
The computer doesn't respond to the power button when pressed.
A portable Mac doesn't appear to respond properly when you close or open the lid.
The computer sleeps or shuts down unexpectedly.
The battery does not appear to be charging properly.
The MagSafe power adaptor LED doesn't appear to indicate the correct activity.
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Another troubleshooting step would be to reset the PRAM as well:
About NVRAM and PRAM
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
You can read more details by clicking on the two links above, but these would be two good troubleshooting steps to try.
Hopefully, this information will help ....
