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 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?

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 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 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

Macbook air will not connect to the wifi network

I recently had to replace my wireless network router and now my macbook air will not connect to the network. it worked fine with the old wireless router. Now, i get a "unable to join wi-fi network" message. The network ID (SSID) and password (WPA) are the same as before. I try to manually enter the password, but continue to get the previous message.
Any help in figuring out how to correct this problem is greatly appreciated.
Also, I have several PCs in the house that have had zero problems connecting to my wireless with the new router. What am I doing wrong?

Hi,
Ever since did the last airport utility update this has been happening.
I believe the airport utility update is solely a software update. Repair permission and repair disk (boot from your installation disk A) may help.
Other wise, http://osxdaily.com/2009/12/22/mac-wireless-problems-guide-to-troubleshooting-ai rport-wireless-problems-on-your-mac/ may help, too.
Cheers.

My Mid 2010 MacBook Pro will not boot

My Mid 2010 MacBook Pro will not boot regularly, in safe mode, in recovery mode or from original OS DVD. Is this the logic board?
I've tried resetting the SMC and pram numerous times and even tried switching out hdd's to try and do a clean install on a new hdd.
If I attempt to boot regularly or from recovery drive the grey apple logo appears for a period before the screen goes black and the power LED operates as though in 'sleep' mode. I'm unable to wake it from this state and the same applies to booting in safe mode.
When attempting to boot from the OS DVD that was originally packed with the computer it just freezes on the language select option, this occurs with the other hdd's I have attempted to use.
Any other suggestions to get it working? I fear the logic board has gone and that the repair won't be worth the money.
Thank you in advance.

Hi JRC8.8,
It sounds like you have been on the right track in trying to troubleshoot this issue. You may want to see if your MacBook Pro will boot directly to the Apple Hardware Test, as outlined in the following article:

My macbook air will not connect to the internet due to a self assigned IP address. I have tried trawling the support forums, but either I can't understand the suggestions, or they don't work. Please explain to me in simplest terms how to fix this. Thanks!

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

My Mac Mail subfolders on my MacBook Air will not sync in alphabetical order. I am assuming it is a setting that I am not finding since my iMac based at my home office is fine, so is my iPad and iPhone. The core source is Exchange.

If you have been using the mac.com Apple ID to make iTunes purchases recently, then there should be no issues continuing to use it with the new iPhone. I would abandon the new ID as you will never get Apple to merge the two IDs. I have had a mac.com ID for years and continue to use it with my iPhone 4S.
Tell us the issues that you encounter trying to set up the iPhone with the mac.com account.

Macbook Pro will not boot beyond grey screen. System freezes.

My Macbook Pro will not boot-up or get beyond the grey screen (with spinning gear wheel.) I've tried all the recommended actions: resetting PRAM, disk repair, permissions repair, re-boot in safe mode etc but still the problem persists. When viewing the safe-boot in verbose mode, the system seems to hang at the stage when it's checking the Airport & Ethernet - the last line on the page reads: "AppleBCOM5701Ethernet: 0 0 setFixedSpeed - logic error, speed any?"
Any ideas how to fix this without doing an Archive & Install?
I'm assuming that if I do an "Archive & Install" then I will lose all my Applications (VLC, Handbrake, MS Office for Mac etc.) Will this actually be the case? Will I lose them.
Any help gratefully received. Many thanks.

Archive and Install just affects the System files, so any apps you have should still be available afterwards. The Installer on the disk that came with your Mac, when you bought it, will tell you this before you proceed. Of course, you can always back out of the Installer if you feel chicken.
Notwithstanding it is still necessary to backup everything. You need to check that Time Machine is set to also backup your Applications folder. It might be set not to do this.
It may not be necessary to worry about this if you have the original installer disc(s). I think any stuff downloaded from iTunes etc can be re-downloaded. However, it's probably quicker to get Time Machine to backup your apps if you can afford the HDD space. It's bound to be quicker than re-downloading the stuff plus any updates. And of course there's those Apps that you have but forgotten about. What about them?

MacBook Pro will not boot

MacBook Pro will not boot. Just get grey screen. When I hold down control + R, I get blank blue screen.

Which model MacBook Pro do you have?
It's COMMAND and R that will take you to your Recovery partion, not Control and R.
If a later model, can you boot into Internet Recovery (booting whilst holding down the command, option and R keys)?

MacBook Pro will not boot after software update

MacBook Pro will not boot after doing an Apple Software Update (of course they will not help you). MONEY, MONEY, MONEY is the name of the game. They can cause your computer to crash and still charge you!
Does anyone have an answer to why my computer is showing a little gear spinning for hours? I have tried several things with NO luck.
Thanks-

How do I uninstall Yosemite please ? Since I upgraded my 2011 MacBook Pro will not boot up

My 2011 MacBook Pro will not boot up following my upgrade to Yosemite. How do I uninstall or downgrade back to the previous version of OS please ?

You can't downgrade or uninstall unless you first erase the drive. Try the following:
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Also see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X

if possible because it is three times faster than wireless.
