MacBook Air won't start up even though it's fully powered. The white screen with the apple logo appears when I turn it on, then it shuts right back down. Can someone help me?
Hey Msazama30,
First, I would start off your troubleshooting by following the steps in this link:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/TS2570
Then, if that doesn't work, try out the information in here:
Step by Step to fix your Mac
https://discussions.apple.com/docs/DOC-3353
Welcome to Apple Support Communities!
All the best,

my macbook air won't get past the white apple screen. I've tried power cycling the batter but won't help
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -
My macbook 2007 won't start up past the logo screen.
My macbook 2007 won't start up past the logo screen. I've tried to boot the computer off the install dvd that came with it but it comes up with a box saying that Mac OS X can't be installed on this computer. It has a yellow triangle over a hard drive in the box. What do I do?
You need to start the MacBook with the original DVD that shipped with the MacBook. then run disk utility on your hard drive to repair it, also repair your permissions.

My MacBook Air won't start it's grey with apple logo Howe do I fix this?
I have 2008 MacBook Air today I can't start up. When I press the power button it shows gray screen with apple logo and that thing spinning . How do I fix this?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again.

This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
Hello, Need help with a macbook air, running mountain lion. I don't know which version because my computer won't start.
It appears to boot normally all the way to where the desktop can be seen and the cursor is drawn properly and the cursor can be moved around using the touchpad. It may or may not login to my wifi network according to the icon in the top bar. I see all the normal icons in the bar at the top - including if I see that the wifi has connected, I also see that the airplay icon appears there.
However, nothing on the menus can be selected using the touchpad by pressing or tapping or any gestures other than moving the cursor around.
The touchpad does however tell if there are 2 or 3 or 4 fingers down because if I for example put 4 fingers down and swipe to the left I get the dashboard, and if I swipe up with 4 fingers I also see the correct screen. And if I put 2 fingers down the cursor does not move which is correct - and if 3 fingers down and move, the cursor moves which is also correct (no windows can be opened though so there are no windows to move around).
Also, the applications popup bar at the bottom of the screen does not pop up when the cursor is moved to the bottom of the screen.
Looks like the keyboard is working OK because if I push the power button in the state decribed above, I get a popup window that asks if I want to shut dwon the computer, and presssing the return key chooses the highlighted choice (shut down).
So... pretty useless computer right now, it will start but can't choose anything or open any apps.
Thanks for any help.OK got it to work... used external trackpad and for some reason it would operate corectly. THen the internal trackpad also started working suddenly also. So problem solved, but no idea what caused it to start working.

Macbook Air Won't Start Correctly
WHello.
I have the previous version of the Macbook Air. When i turn it on, everything seems to be normal. I input my username and password and login.
But then, the icons on my desktop won,t show up. The dock and the top tab is in place. The computer is working -somewhat slowly- but my icons on the desktop won't show up and my keyboard shortcuts don't work. For example, i had command+d set as show desktop, but this command won't work. Neither does the right click with two finger tap on the trackpad.
What could be the problem ? Any suggestions ?
Thanks in advance.Restart.

My MacBook air won't start? Black screen
I closed my MacBook air and when I opened it again it won't start. I tried to reboot it but the screen stays black. I hear the ventilators turn slowly when I try to turn it on but nothing else happens. The light on the macsafe charger is on. A few hours earlier the charger won't work but the MacBook worked well. After a while it worked again and I charged the computer and surfed on it without the charger later. It happened a little later. I tried to reset the PRAM and the SMC but the screen still stays black. I tried to start it with a external hard drive but nothing. I tried to connect an other screen but still nothing. I'm desperate!
I have an appointment at the genius bar next Tuesday but I hope it will start again until then.
What can it be. Is it possible that the charger had a diffect and that something overheat?
Thanks in advance for your help. And sorry for my English, I'm french.Hello!
My friend is experiencing this very issue and your response would be most helpful as he is out of warranty. Please do keep me posted! -
Macbook Air won't start up past the "apple" page, and has a spinning icon. help!
The computer was left on for over a week while I was out of town, came back and it was slow, then it started doing the "spinning beach ball" so I shut it down and now it won't start up again.
Hey Sarah.
The spinning beach ball of death is a tricky issue to fix.
You can delete everything in the caches folders located at:
~/Library/Caches
/Library/Caches
Also try an SMC/PRAM reset:
PRAM RESET:
Shut down the computer.
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. You must press this key combination 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.
SMC RESET:
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.
If you still boot to the apple screen your next option is to boot to the Mac OSX install DVD and run a disk check/repair.
Hold down option with your OSX DVD in your drive, click on the cd that appears, boot to the OSX DVD.
Click on utilities in the menubar, go to disk utility, select Macintosh HD, run a check/repair.
If this fails you'll need to run the Max OSX installer and reinstall your Mac OSX.
P.s since you have a Macbook Air your install DVD is the usb stick you would have got with your MacBookAir. -
Macbook Air won't start after Yosemite update
Hi all,
I have a late 2013 model macbook air (just out of the 1 year warranty). I updated to Yosemite last night and to complete the install I restarted the macbook when prompted, but it never turned back ok.
I can now hear the macbook trying to start up but it does nothing. I have tried to reset the SMC and I can see the power adapter change colour from orange to green for a few seconds but this does not appear to fix the issue.
Any help is appreciated,
PeterIf that doesn't work, this link may help you identify the problem
https://www.ifixit.com/Wiki/MacBook_Air_Troubleshooting#Section_MacBook_Air_won_ t_turn_on
If you still think its SMC issue you can try manual SMC Reset (At your own risk ). Steps are..
1. Open the lower case
2. Disconnect the battery connector and after few secords connect it back and close the lid

I contacted Apple support because I couldn't download apps on iTunes.
I got called back by Apple who redirected me to a technician.
The technician had access to my macbook air screen and via her directing me on the screen and via telephone she had me remove a bunch of stuff from my computer.
After that it seemed initially that the iTunes problem was fixed because the iTunes box showed that it was downloading the app. But it just said it was dowloading it but there really wasn't any progress visible.
So I decided to restart the computer but it would never start back up.
I scheduled an appointment at the Genius bar closest to me for tomorrow.
Is there anything else I can do/try?Since I do not know what she had you remove it will be hard to say what exactly to do. If your original problem was automatic downloads here is what apple says.https://support.apple.com/en-us/HT202180 First i would try a pram reset. Command/Option/P/R keys at startup for three chimes. Then if no startup Go to recovery. Command R or Option R at startup. Then use the utility option and check /repair startup volume and also permissions. If still no response you might have to use recovery to reinstall your operating system. You should have your files backup up even though a reinstall does not normally delete personal files.

I shut down my MacBook Air last night with no problems. This morning I pushed the power button and I got a circle with a slash through it and a rotating Apple. My OS X won't load. I chone the disk utility repair (based on suggestions on other forums) and it's been "updating boot support partitions for volume as required" for over 30 minutes now. Not sure if this will work. My next option is to reinstall the OS X Maverick. I'm worried because I don't have a backup and need the files on my laptop (dumb move and will never do that again). Anyone else have problems like this? Could you get your files off the hard drive?
Welcome to the Apple Support Communities
What are you referring to with "changing colours"? During startup, you should only see a grey screen with the Apple logo. If the color is different or it changes, the graphic card or the display is damaged, so take the computer to an Apple Store -
Macbook air won't start without charger if powered off for at least 5 hours.
Hi,
I have macbook air and it doesn't turn on if I shutdown it for at least 5 hours and next time I need to start i have to plug the charger just one time after that It starts and can be used for whole day.
I am not sure what the problem is I charger battery to 90% before shutting it down.
Yes my battery cycles are too much. Details are :
Health Information: Battery cycles : 785
Condition : NormalHi there abhishekgahlot,
You may want to try resetting the SMC as an initial troubleshooting step. Additionally, take a look at the battery condition. The articles below have more information.
