My macbook air wont boot up

I get the grey screen with the spinning timmer animation.

See if you can boot into safe mode, if not youll need to reinstall your OS, how old is your AIR? Yours might have come with a boot OS memstick, of if running Mountain Lion you can erase and reinstall via net connection.
Mac OS X: Starting up in Safe Mode
Learn how to start up in Safe Mode.
To start up into Safe Mode (to Safe Boot), do this:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup in Mac OS X v10.4 through Mac OS X v10.6.8, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically. During startup in Mac OS X v10.2 through v10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
To leave Safe Mode, restart the computer normally, without holding any keys during startup.

My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

That normally indicates an issue with system memory. The startup sequence can't complete the boot due to a memory issue. Take it in for service.

My macbook air wont boot up past the loading screen. UPDATE

My 2008 macbook air will turn on, and then go to the apple screen with the loading wheel, but after a few minutes of loading it just shuts down...
Here is an update of the problem after i messed around with it for a bit.
I start up the macbook while holding Command+s
Then it brings up the prompt.
I then type: /sbin/fsck -fy
It then outputs a message saying:
disk0s2: I/0 error.
Invalid sibling link
(4, 42746)
**The volume macintosh HD could not be repaired.
/dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
After that, i type in: /sbin/mount -uw /
Then I type: exit
It runs the logout scripts and then immedietly boots up fine, like the computer has no problem.
It works fine like this, but i dont want to have to do those steps every time I want to use my macbook...
Any help on how to fix this?

I have a similar problem. Not sure you're on here (since the post is really old) but did you manage to work it out? How?

My Imac froze earlier today as I was dragging an image from safari into indesig and when it froze the weirdest pattern overlaid the screen. It looked just like the opacity pattern from photoshop with grey and white squares. I turned the computer off using the power button and unplugged everything.
Now when I try to start it these weird lines appear on my start up screen (see link)...
http://meijerladdaruppgrejer.wordpress.com/2012/07/24/oops/
as you can see the apple and the wheel appears as normal...
... then it moves to a normal looking white screen (perhaps a bit greener than usual) and around 30 seconds later freezes at the blue screen.
I've tried the cmd + alt + p + r several times but it won't help.
If i press alt during start up I can see and choose my hard drive but just end up at the blue screen again.
Can I try starting it up in safe mode or something?

My macbook air wont boot.

Hello everyone.
I dont know what is going on with my mba. I just cant turn it on. No sound no fan,nothing. The light charger is green,sometimes is red. This is the third time. Its only happen when i shut down my mba without macsafe. I dont know why. Tried smc reset but nothing different. I even shake my mac but still nothing. I dont know if it something wrong with the logic board.
Thanks for the help.

Do not shake your Mac under any circumstances.
only happen when i shut down my mba without macsafe
What exactly is, "macsafe" ??
And which OS X is installed?

Your boot drive is damaged in some way. If you have an original installation disc, you can boot from that and run Disk Utility. From DU you can select your internal hard drive ("Macintosh HD" is the name Apple puts on it - you may have renamed yours) and select "Verify Disk". If errors come up, try "Repair Disk". If it repairs, then you should be able to restart and boot from it. If it doesn't show up or won't repair, your drive is probably hosed.

My MacBook Air wont startup after login

my MacBook Air wont startup after login???

Try to boot your computer in Safe Mode: restart and hold the shift key down.
This can take some time, so be patient.

If thyis leads to the computer booting, you can restart without holding the shift key down.

My MacBook Air wont turn on. HELP!

My MacBook Air wont turn on, I bought this past September (as a birthday gift for myself) and this Sunday I was using it perfectly, then at night it didn't turn on. I tried several times to turn it on and it did once, I thought "Yes finally" but two minutes later it turned off and never to turn on again. I have taken care of my mac book so much, that I really dont know whats wrong. I bought on I trip I did to the US and I live in Honduras, we don't have an Apple store here not even a Genius bar for me to go and see whats the problem, I thought this machines were for life, like I literally cried so bad because I had to work SO hard to buy this computer and now its just not working.. why? I dont know. If theres any tricks to making this turning back ON please let me know.
Thanks APPLE...

okay, since you are in Honduras, I'll share what my Genius told me when he reset the SMC on my 11 inch mid-2013 Mac Air yesterday. He took it in back of the Apple store, came back in about five minutes with everything working. I asked him if there was anything I had done to cause the problem, he said no, except it might be better to actually "shutdown" the computer from the Apple pull-down menu when you aren't going to use the machine for more than a couple of hours (e.g., overnight). If the instructions in Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support didn't work, As for self-repair, he said this is what you would have to do (but he also said, you really don't want to do this yourself): you have to remove the bottom of the Mac Air (under the keyboard), and disconnect the battery. Then, with the battery disconnected, you plug in the power cord attach it to the Air, and then turn on the computer from the keyboard on/off switch while powered only by the power supply. That should reset the SMC. Then shut down the system from the Apple menu (not the keyboard button/switch), reinstall the battery, replace the bottom/cover, and see if it works. Just remember that fiddling inside the back of a Mac can be dangerous to the Mac and your warranty! Good luck

How do I get macbook air to boot up off of the network

how do i get macbook air to boot up off of the network

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.

My (UK bought) MacBook Air wont open open Chilean (.cl) websites - anyone know why? Or what I can do to change this?

Go to the main Library folder and look for a folder called Application Support / Microsoft.
There are a few folders in there, and you may have to do some digging. In one of them (mine is called MAU2.0), there should be a file called Microsoft Autoupdate. Open it.
It looks like this:
check the button for manual updates.
That should let you open the apps without triggering an automatic update.

Yours would appear to be an original 2008 vintage model, which unlike the more recent MBA systems did not have a recovery partition.
There is no downloadable source of the MacOS reinstall disk that I know of (none that are legal at any rate) but you should be able to get a copy of the DVD from Apple. The user guide for this model (http://manuals.info.apple.com/en_US/MacBook_Air_Users_Guide.pdf if you also do not have that) explains the procedure for MacOS reinstall using the original disk.
