My MacBook Air will not boot up all the way.

My MacBook Air will not boot up all the way, it only allows me to sign in and then it stays on a white screen. I tried restarting, rebooting, recovery and smc reset. Nothing works, it stays with the same problem. How can I fix this?

Try a safe boot:

My macbook air will not turn on all the way

When I try to turn on my AMcBook Air the screen will not get past the thinking circle

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. 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.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your 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 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
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.

HP Pavilion Slimline s3707c PC will not boot up all the way

HP Pavilion Slimline s3707c PC will not boot up all the way; gives the following message:
Entering Setup
<F10=setup> <F11=System Recovery
<Esc=Boot Menu> <F9=Diagnostics>
Tried to install recovery disc; did not respond.
[Personal Information Removed]

Hi wjackson95,
When you get to the screen mentioned below, can you press the F11 key to enter the Recovery system that is on the hard drive? Alternatively, if you can press F10, you can go into the BIOS and change your boot order to put your disc drive before the hard drive so that the PC boots to your Recovery discs. NOTE: You may have to press F10 or F11 multiple times to get it at the right time.
You might consider opening your PC to see if it has dust buildup. If your PC has overheated, it can cause it to not boot. It can also cause heat damage to the interal parts.
For more detailed boot troubleshooting, see this HP Support document:

MacBook Air will not boot. Error Message says "Your Computer restarted because of a problem."

MacBook Air will not boot. Error Message says "Your Computer restarted because of a problem."

If you can't start up and log in in the usual way, try in safe mode.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally 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.
Log in as an administrator to carry out these instructions. If you have only one account, you are the administrator.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode.
If you're able to log in, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.

My macbook air will not boot

My Macbook Air will not boot. It starts and hangs up at the apple logo. Is there a bypass to see what the problem is?

Try a Safe Boot by holding down the Shift key between the startup tone and the Apple Logo. This will take longer than a normal boot and display a progress indicator. If successful, Go to System Preferences > Startup disks > select your Boot drive and restart.

My brand new MacBook Air won't turn on all the way.

Hi my brand new MacBook Air won't turn on all the way. If I try to restart it or shut it down, it will go like it is starting up, but goes to a gray screen and stays there. I can see the mouse and move it, but it won't turn all the way on. What is wrong with it? It had been working fine since I got it, but today it hasn't been.

You may have to see if troubleshooting this issue can help, though the instructions on a process of elimination by symptoms are tedious in the following support article, and are suggested to be performed ahead of trying the process described in the title.
•Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
For the actual SMC reset, note subsection in above, instructions click-open on blue text:
>Resetting the SMC on portables with a battery you should not remove on your own
If the computer does not shut down, and just hangs there, try pressing the power button down for 15 seconds. Check the suggestions in the above article to see if any of them can be used, if the computer will power-up.
There is another item that sometimes can help, but the main issue you say could be resolved by the SMC reset; this other thing is involved NVRAM (non-volatile random access memory) so here's an article about it.
•About NVRAM and PRAM:
http://support.apple.com/kb/HT1379
>Resetting NVRAM/PRAM opens in above, click-to-see instructions on how to reset.
You may have to call ahead to the nearest Apple Store for an appointment to see a Genius; or at authorized reseller, their service product specialist who should be trained to understand how to proceed, just in case there is a hardware issue behind the symptoms. When you call, be sure to have the serial number and purchase date available, when you call an official store.
Or use the 'Apple - Support - Contact Apple Support' to start the process...

Hopefully this helps somewhat.
Good luck & happy computing!

Itunes library will not close down all the way

My iTunes library will not close down all the way. When I close the library I am unable to log back in or turn my computer off because itunes is still running although I x'd it out.

You're right, you shouldn't have to do that.
Well, you didn't say whether you've tried uninstalling & reinstalling itunes. Make sure it's installed with an admin user account. Then go into the WIndows Event Viewer and see if there are any error messages about any of the itunes processes in the installation package. That could give us a clue of what's going wrong.
Another thing that could be causing the problem is the "apple push" part of itunes, APSDaemon.exe. Read wiclee's post here about it.

My 13" MacBook Pro will not boot up - all I get is blank screen

The MacBook Pro is only 10 months old and is up to date on all OSX updates. I have been using it all day and suddenly this evening it just went to a blank screen and will not boot up. No fan, nothing. Nada.
I have tried the following:
checked magsafe and it is clean of any dirt
checked battery (pressed button on side of Macbook and got 6 green lights coming up)
There are no USB peripherals connected
tried pressing CMD+CNTRL+Start button and nothing happended
tried holding down start button for 30 seconds
The mac has not been dropped or had water on it.
Any other ideas?
Cheers

Which OS do you have...if it is Snow leopard then press shift while starting up, i.e., immediately after pressing power button
if the os is Lion or Mountain Lion press command+r to goto the restore thing and then disk utility to rectify your problem

My MacBook air will not boot up completely

My Machook air has crashed. While using iPhoto to review photos taken with a 12 mp camera, the computer warned me in several languages to restart. This has occurred on several occasions using iPhoto. Upon shutting the computer down and after restarting the computer, it failed to boot up completely, shutting off halfway through the process. I tried resetting the pram however the computer only provided me with a choice of repairing the hard drive or reformatting the computer.
After several attempts to repair the HD/Disk. It gave a message to save what files I could and reformat the drive and reinstall the softwear. However the computer will not let me do so and gives me a message that the HD is locked. Futher attempts to restart or reset ends in failure. The computer will not boot up completely before it crashes/shutsdown.
Thanks in advance for any help.

Make a "Genius" appointment at an Apple Store to have the machine tested.

Macbook Pro not booting up all the way, weird problems

Last night I was using my Macbook Pro, closed the lid then came back later and when I opened the lid it wouldn't wake back up. Shut it down by holding the power button, then tried booting it back up. You can hear the CD/DVD drive spin up, (got my copy of X-Plane in there) but nothing else happens. Keyboard backlights never turn on, display stays dark, and the sleep light never lights up all the way either, just stays dim. Leave it for a few minutes, then close the lid and the sleep light gets bright like the computer is awake, and you can still here it running.
Sounds like classic SMC issues right? Well tried resetting that several times, no luck. Reset the PRAM while I was at it as well, no luck. Really not sure what's wrong now.
Macbook Pro was purchased spring '08, can't remember all the specs off the top of my head but it was the top-of-the line processor, 2-gig of ram, the nvidia 8600 video card. I've heard that there have been some issues with that card however I'm not yet convinced that this is a video issue. Software update ran just a few days ago, so I'm running whatever the latest version of mac os X is. (10.5.??)

Here's a link to the NVIDIA program:
http://support.apple.com/kb/TS2377
There is a specific test they run to diagnose this problem. If it pulls the right error code, you get a free logic board replacement. Print out a copy of the article and take it along--oddly enough, there are still a few Apple guys that don't seem to be familiar with this program.
So far I have not experienced the NVIDIA problem myself, but I have read a number of posts about it. Some people have reported multiple problems--some so severe that their Mac won't boot up enough to run the test. However, since your Mac sounds unusable the way it is, you may as well make an appointment at the genius bar and see if you qualify for a replacement logic board. That could cure many things.
Good luck!

Macbook Pro will not boot, at all!

Hi all, Thanks in advance for this...
Specs: Macbook pro 2010 model with Snow Leopard (updated recently). 250gb Seagate HDD
I shall start with yesterday, when i let my battery drain to nothing so that it could be recharged fully and effectively.
Afterwards i booted up the Macbook fine with no problems and it sat there charging to 100%.
I shut it down the normal way and returned to it about an hour later when the following occurred:
Upon starting i received the apple logo and the spinning wheel, accompanied by the loading bar which gives up halfway and turns the computer off.
I have tried the following to rectify the problem:
1: tried running the install DVD to boot up into Disk Utility to repair any file corruptions possible, but the spinning wheel and logo just sits there forever not doing anything.
2: Tested the Hardware by using the common check (forgotten how i did it) checking the RAM state and other logic board functions but it came back clean.
3: I ran single user mode - /dev/rdsk0s2 to try and find out the status of files but it Exited under Signal 8 Saying - The volume Macintosh HD could not be verified completely.
4: Based on other forum subjects relating to the signal 8 problem (HDD failure), i swapped HDD and placed one in that i know works hoping to install OSX onto that drive. But again, it holds at the spinning wheel and doesn't go any further.
5: any other commands i tried running under single user mode just brings back: Permission Denied -/dev
6: Tried using my Windows machine as a donor DVD R drive to install, but the Macbook won't give me anything else except 'Macintosh HD' drive when i hold down the 'Alt/option' key, aiming to use the network to my advantage and rule out Optical drive failure on the Mac.
I am running out of options here, i would like to try and install OSX via Memory stick but i have only a windows Xp desktop machine here to help me and it cannot read all the files on the install disc to copy over. Also i do not have the money available to download expensive software to help me.
Stupidly i haven't been able to back up my files and hopefully this Friday coming i will be able to copy all files over to my Mums Macbook as i cannot access the GUILD protected drive on Windows.
Now the way i assume things have happened is by the following: Letting the battery run flat has corrupted a few files which in turn won't let the Mac boot up anymore, But i cannot rule out the Optical drive failing unless i work out how to install OSX off of a Memory stick (bearing in mind i don't have another Macbook to hand until next friday). If the Optical drive is fine then i can only assume that the logic board is dead?
I need to fix this problem ASAP and i have no other ideas on what to do, hopefully you guys/girls can give me some extra field to play on.
I would take it to Apple but i'd rather get some advice before i take that route, Ideally also because i have lack of funds to help me here!

Applejack is just a command-line "front-end" for a number of different command-line tools you can use in single-user mode, and I'm not sure whether it's Lion-compatible. You can always try booting into single-user mode and executing:
/sbin/fsck -fy
That's unlikely to solve your problems, though. Since you can't boot from two different hard drives and your optical drive, that indicates there's a more serious hardware issue, or multiple hardware issues.

Macbook air will not boot 10.5.7 after screen replacement

Hello
Following screen replacement on original macbook air I can only take system to 10.5.6. Will not update to 10.5.7 or 10.6.
Any suggestions?
GeorgeV

BTW, I see the threads on the Thunderbolt update kernel panics. I was kind of hoping Apple resolved the problem since I thought they had pulled the update. Anyway, I do not *think* I am getting a Kernel panic as the boot does not even get as far as the Apple logo. It just sits on the gray screen and does nothing.

MacBook Air will not boot to previous image

I got a new MacBook Air for my company and used a prior image that has been used on previous model MacBook Pro's (Retina 15", 13", Air 2012, etc). When I apply the image, it does not boot. Is there any way I can get the dmg to boot on the new laptop without me having to rebuild it from scratch?
Please advise.

Welcome to Apple Support Communities
What Mac OS X version has the image got? Note that the new MacBook Air isn't compatible with OS X 10.8.4 or older. If the image doesn't contain this version, you won't be able to use that image. Also, note that the MacBook Air may use a special version that isn't compatible with the OS X 10.8.4 version available for other Macs, so you won't be able to boot from the image

My MacBook Air will not boot up all the way.
