We will first try to reset your PRAM.
1.Shut down the computer.
2.Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3.Turn on the computer.
4.Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears. Let computer chime 4 times
5.Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6.Release the keys.
Please let me know if that didn't work, so we can continue troubleshooting
I will stand by while you try those instructions
When computers have trouble booting up, some possible causes are Hard drive failure or a corrupt operating system. We are going to determine which one it is.
Turn your Mac off. Turn it back on and this time hold down the Command key (right next to space bar button) and the S keys at the same time. Then type the following command...
/sbin/fsck -fy (note the space between fsck and -fy)
If you can't run /sbin/fsck - fy then type only fsk - fy
Hit return and the disk utility should run and let it finish. When it finishes and there is no error, then type reboot and hit return. Let the Mac boot up. (Disk Utility will fix all system errors, bad preferences files etc)
I will stand by while you try putting your computer into single user mode
Were you able to boot to a black screen?
When you typed in
/sbin/fsck -fy what happend?
Lets try a different route. What operating system are you running?
I understand, I will do my best to assit you. When did you purchase your computer?
Have you ever updated your operating system?
I assume you no longer have the install disk too correct?
Ok. Can you press and hold the power button until the computer powers off. Let me know when the machine is off
Press the power button and immediately press and hold Command+ S (the command key is located right next to the space bar) Press both buttons until a black screen appears
Ok, now type in the following command.
Your computer will now check to see if your hard drive is ok. This can take some time
Ok, let me know when it is done checking your computer
How is it going so far?
At the bottom of the screen, does it appear to be checking anything
Can you read me the last line on the page?
it should look simular to this
/sbin/fsck -fy did you remember to put a space between fsck and -fy?
When you hit enter, do you now see
Ok, we will need to start again. Please remember the space between fsck and -fy)
1.Turn your Mac off. Turn it back on and hold down the Command key (right next to space bar button) and the S keys at the same time. Then type the following command...
Ok, allow the computer to check your system
Did this happen after you typed in /sbin/fsck -fy ?
So the computer ran a system check and then rebooted?
Hmm that is strange. Lets try to boot into safe mode. This will take some time to boot and you will see a solid progress bar underneath the apple logo.
1.Make sure your computer is powered off.
2.Press the power button. Immediately after you hear the startup tone, press and hold the Shift key.
3.Release the Shift key when you see the gray Apple and progress indicator.
4.Let the Mac boot up...(This can take some time)
Did the progress bar show up under the apple logo ?
No it should look like this
When you booted your computer, did you immediately hold down the command and shift key?
Im sorry, it is just the shift key that needs to be pressed
Ok lets try one more time
As soon as you hear the chime
Press and hold only the shift key until you see the apple logo
Ok so it appears that your computer may have issues with the hard drive. Do you have a backup?
When you unpacked your macbook air, do you remember seeing a small jump drive?
Since your computer does not boot because of the hard drive or the operating system, we will need the installation drive to boot to. This will allow us to troubleshoot further. None of the steps we tried so far are working which leads me to believe there may be in issue with your hard drive
We can try one more time to put your computer into single user mode and type in a different command. If that does not work, we will defiantly need the installation disk. If you can not find it, you will then need to take your computer to your local apple store where you can use their install disk.
1. Shut down the computer
2. Power it back on and this time hold down the Command (⌘) key and the S keys at the same time.
3. type only fsk - fy
Does it look like your computer is scanning for anything?
try /sbin/fsck -fy
It looks like your hard drive is failing or has failed. Or may just need a simple re-installation. How far is the nearest apple store from your home?
Ok best of luck. Im sorry for the not so great news. I will also follow up with you in 2 days to see if you were able to obtain an installation disk
Thanks for the follow-up. My tech friend downloaded everything to a hard drive, wiped the laptop clean, re-installed all the data and I now have a hard drive attached that is backing up everything.
Working well, although when the hard drive goes again, it's time to buy a new one.
Thanks for the time spent.
