Hope someone can help!
Thanks

You replaced the the SSD in a MBA that cannot be user serviced, so that's quite an accomplishment. Your model does not require a firmware update to use Internet Recovery - Computers that can be upgraded to use OS X Internet Recovery. Here's the process you follow:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

How can I reinstall EFI firmware on Macbook air 2011?

There are only EFI firmware update for Macbook air 2011.

Can't install SMC Firmware Update for my MacBook Pro 15" early 2011

Can't install SMC Firmware Update for my MacBook Pro 15" early 2011

Check your Network control panel and turn off Auto-Proxy setting.
This is one of the top #4 "how can they do this' pet-peeve errors.
The other is the often slow 8 hrs to download 600MB even on 10Mb+ cable.
Another, 'the drive cannot be partitioned because there isn't enough contiguous unfragemented free space; some files are locked and cannot be moved."
If auto proxy isn't it, router/modem and DNS settings.

MacBook Air 2011, running Lion 10.7.2, and Safari won't load any pages. Firefox loads everything just fine. What's going on?

I have a MacBook Air 2011, running Lion 10.7.2, and Safari won't load any pages. Firefox loads everything just fine. What's going on?

d Pacifist to reinstall both the Safari
application and the WebKit framework
was that before the 10.4.6 combo was applied?
Nope, I tried the Pacifist route after applying the combo update.
It does sound as if webkit is busted at the moment.
What version of osx is on your install disks?
Not sure, I'll have to check them.
I'd like to avoid a archive & install, but I'm beginning to think it's my only remaining option.

Whatever you read was incorrect. You can upgrade directly to Mavericks. It is in the App Store and is free.
Snow Leopard predates the operating system you already have. That's the reason it will not install on your MacBook Air. You spent $20 needlessly for it, but it's yours to resell if you wish.

After installing Mountain lion, macbook air 2011 very slow

After installation of Mountain lion my macbook air 2011 got very slow. There has been a firmware upgrade too. Can you help?

Hi guys! Just installed ML on my early 2009 MBAir (after market upgraded to a 240g SSD, but still just 2g of ram), and I panicked a bit at first when it turned out to be painfully slow and not displaying right (+slow trackpad!).
Bear in mind that the first thing ML will do is index your files for spotlight, which takes a while and is a bit of a resource hog that will slow everything else down and cause your machine to heat up.
I let it work all night, but by morning, my CPU usage was STILL at 100% and everything slow...
Activity monitor showed nothing over 10% CPU usage... First tip was to display ALL processes in Activity monitor, and not just MY processes, to see what exactly was sucking up my CPU!
Then, and it seems to often be the culprit on MBA's, it turned out that the kernel_task process was using up to 170% of my CPU usage (!). Problem is, that process sort of does a million things, so it can be hard to pinpoint the actual issue.
One of the things it does though, is work against overheating...
Given the download+install+indexing, my machine had been working all day and night, and was indeed getting super hot. Turning it off and letting it cool down for a whole fixed it all.
Kernel_task is back to normal, CPU usage is normal, display and trackpad are back to perfect. And in the end, ML is snappier than SL for me, even with the bare minimum in memory!
Good luck! <3

Dolby surround sound with a Macbook Air 2011

Hi everybody,
I am really struggling here, is anybody know how to have a 5.1 dolby surround sound with the Macbook Air 2011 ???

Is this the latest version of iMovie?
Drag the app from the Applications folder to your Trash (don't empty yet). Also drag the .plist file to the trash by going to Finder > menu bar > Go > hold down Option key > Library. Scroll down to Preferences and place these in the trash (if you only have one, that's fine):
com.apple.iMovie.plist
com.apple.iMovieApp.plist
Than go to the app store and re-download your iMovie purchase. Install and check for any updates.

Offline Installer for Macbook Air 2011 & Mac Mini 2011

I understand that Macbook Air 2011 and Mac Mini 2011 uses a pre-installed OS X Lion with a different build number (11A2063).
However, it seems that with 10.7.2 , there is only 1 build number: 11C74 , as per http://support.apple.com/kb/HT1633 , does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?
Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?
P.S. I am seeking an offline solution because the recovery partition has been damaged, the internet recovery doesn't work (error 3403F & 4403F), and the recovery disk I have created with http://support.apple.com/kb/dl1433 showed an error "could not find installation information for this machine". And the Apple Authorized Service Providers are charging $150 for a simple restoration of the recovery partition.

"does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?"
Yes.
"Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?"
I don't believe there is a 10.7.2 stand alone installer. 10.7.2 is an update file.

You are using Snow Leopard so you have no OPTION+R shortcut. You need to boot the computer from your Snow Leopard DVD or USB flash drive.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

How do I connect my MacBook Air 2011 to a projector?

How do I connect my MacBook Air 2011 to a projector?

It depends on the input connection for the projector, but since many are rduced resolution, VGA seems to be the prevalent common connection.
It's just a matter of buying the adapter that adapts VGA to the Mini DisplayPort/Thunderbolt port on your Air. If it is a DVI or HDMI connection input on your projector, the online Apple Store carries that as well.
This adapter and sufficient length VGA cable is all you need for VGA.
Here's the DVI adapter.
For some reason, I am unable to bring up the Moshi HDMI adapter on Apple's site.

If you used Boot Camp to install Windows you may use Boot Camp to remove it and return your drive to as it was.

Connecting Macbook Air 2011 to Epson projector for Keynote

Hi,
I'm trying to connect my Macbook Air 2011 to a brand new Epson (Powerlite 1760W) projector for Keynote presentations.
I bought the recommended Monoprice mini cable from the Apple store but I can only plug it into my MBA (small squarish socket), the other end dosen't connect to the projector. It seems the projector wants a VGA cable into it.
I'm lost. Do I still need the UBS cable between the two? Do I need a USB / VGA cable instead?
Thanks in advance.

Alison,
In looking at the technical specifications (on Epson's site) for this device it would appear that you can make HDMI work - http://www.epson.com/cgi-bin/Store/jsp/Product.do?sku=V11H361120&BV_UseBVCookie= yes
That being said, the HDMI end on the adapter and on the projector are most likely female. So you'll need an HDMI cable (the length will vary on how far the machine is away from the projector) but I suspect a 3 or 6 footer would work just fine. The cable is a male-to-male.

Is the Macbook Air 2011 able to run the Apple Cinema Display 30" ?

Hello Everyone.
So, I am about to buy a Macbook Air 2011 11".
I want this product because of the ssd driver and the versality of such a light object.
The things is that i work at school with a laptop, and when i come back home, i use my Apple Cinema Display on my Macbook Pro with the Dual Link dvi Adaptator (which cost me 98€ ouch !! ).
So i read that there were kind of retro-compatibility between Thunderbolt and Mini-Display Port on the new Mba.
Is the 2011 mba able to run my external display ?
Thank you.
Nicolas.

Yes.

Guy would this be of any help:
To start up your computer in Apple Hardware Test:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears. If Apple Hardware Test does not start up, see the Additional Information section at the end of this article.
Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
It takes a minute or so for Apple Hardware Test to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
The Apple Hardware Test console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Your test results will appear in the window in the bottom-right of the console.
To exit AHT, click Restart or Shut Down at the bottom of the window.
