Mac air won't startup completely (black /white text, info keeps popping up and then it restarts over and over)

Hi so I had to force shut down my Mac air because it froze, when I turn it on it first tells me that I had force shut down so press a key to start up, then it goes to the apple screen, then black strips with white text pop up, then it restarts again. So I looked up what to try to do and I did the "command/r" and it comes up with options, but I don't believe that I set up my time machine backup or something because nothing comes up after it "searches" for a back up thing. and it won't reinstall OS X because it can't find the installation information. And the disk utility doesn't work because it says that I need to "back up as many of [my] files as possible , reformat the disk, and restore [my] back up files" .
I'm not sure what to do but I have a lot of school things I need on it.  So I hope there is some possible way to not erase any of the info on my internal hard rice. I'm also not that good with computers.

Welcome to Apple Discussions.
Help us help you. The more complete the description of your problem (what MBA you're using - there are many versions going back to '08, what OS you're using -there's a lot of those too- and an iOS will not work with an MBA you must be using some versions of OS X 10.5.x - 10.9.x) the more assistance we can provide, and, the sooner we can provide it..
Sounds to me like your SSD and/or your OS is corrupt.
Boot into repair and use Disk Tools->Disk Utility-Disk First Aid: repair disk to try to fix your boot volume. While you're there also do repair permissions.
Reboot holding the Shift Key down until  you see a progress bar at the bottom of the screen and log in. BACK UP YOU IMPORTANT DATA.
Reboot normally (if you can't come back here)

  • My macbook air won't get past the white apple screen.  I've tried power cycling the batter but won't help

    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.

    without more information, I assume you mean a blackout from sleep issue.
    Go to system preferences > energy settings > raise the "turn display off" setting up to as needed, say 5 mins. or 10 mins.
    AND ...
    unchecked the "Put hard disks to sleep when possible" in both the battery and power adapter tabs.

  • Just bought a new iphone4 and was loading os6 and now it won't turn on. the apple glows like it is starting up, then the screen goes black and then repeats the same process over and over. i have tried to reboot multiple times now

    just bought a new iphone4 and was loading os6 and now it won't turn on. the apple glows like it is starting up, then the screen goes black and then repeats the same process over and over. i have tried to reboot multiple times now

    I am assuming the phone was working prior to you installing IOS 6? Did you use itunes to install IOS 6 or just run from the phone?
    When I tried to do the Over The Air update to IOS6 on my iPhone 4, it errored out and I had to connect it to iTunes and select "Restore" from the summary screen after iTunes finds the phone is connected. If this works for you, it will go through a couple of reboots that take a few minutes to complete. It should then give you the option to start with a fresh new phone or to use one of your previous backups to load your contacts and other information, provided you have backed up the phone previously.
    I hope this helps you my friend!

  • My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

    Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
    You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
    I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
    Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
    Thanks. Hope my other question has an answer out here.

    Hi, I downloaded Yosemite this evening. It downloaded fine, it installed fine and then it restarted the Macbook. Now it seems to be frozen. I have nothing but a grey screen with the apple logo and a bar that is half black and half grey. It's been like this for over an hour. Should I worry or is it still working at something? How do I fix this if it's not still working at installing something. Thank goodness for this poor old pc as backup.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.

    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    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.

    Blue screen of death? I just updated my MacBook Air with the latest OX (25 Jun 11). When I restart - I get the Apple logo and then a blue screen and nothing else. Help!!!

    Insert the install disk and press c on startup. Select your langauge then, if there's a menubar click utilities then click Disk Utility. If you didn't see the menubar continue with the installer until you see it.
    Once in disk utitly select the drive and repair permissions.
    After the repair is done, quit the utiltiy.
    You can try to reboot and see if it works if you reboot, but if it doesn't repeat the same as before again.
    Now you can continue with the installer and install the os.

    In more specific terms. The apps that came on the iPod like the weather and maps and whatnot have been working flawlessly. It's just when I download an app and then disconnect from wifi it's almost like I'm on a timer until the app stops working. It acts like it wants to open, the screen flashes black then resets to the home pages. I've tried all of the basic fixes, rebooting, reseting, uninstalling then reinstalling. But like in my...long...question, the reinstalling option only seems to be a temporary fix. I just recently downloaded the 5.1.1 udate (I think that's what it was) does that have anything to do with it, or am I just derpy when it comes to iPods?

    Try the other suggestions here:

    Then try a restore.

    This could well be the notorious Mac Defender - which is an annoying program that tricks you into thinking that your Mac is infected with a virus, when the only infection is Mac Defender itself.
    When surfing the web never EVER click on a link that says "Free anti-virus scan" or "Scan now" - they are nearly always scams which will end up infecting your computer.  Although Macs are resistant to viruses, they're not resistant to user stupidity.
    If you Google "Mac defender" then you'll find plenty of sites with instructions on how to remove this minor nuisance.  Take this as a warning that you need to be more careful in your surfing habits.

    Are you running Leopard on your Mac, Laurie?
    If so, try instead updating to iTunes 10.6.3.25. (That supports earlier models of iPhones running iOS 6, even though it can't run the new iPhone 5s.)
    A .dmg installer for iTunes version 10.6.3.25 for Mac OS can be found at the following download page on the Apple website:
    iTunes 10.6.3

    When Microsoft decided not to support Windows Media any more, they made Flip4Mac available for free. If you have not taken advantage of that free download, this might be a good time.
    It may not completely solve the problem, but your Mac will play more with the free player. No need to pay for the Upgrades.

  • I was looking at a tanning website today and then I logged off and went to eat lunch.  When I came back, I got on Facebook and on the side were ads for tanning.  What do I do so that this won't happen?  I feel like something is wrong.

    I was looking at a tanning website today and then I logged off and went to eat lunch.  When I came back, I got on Facebook and on the side were ads for tanning.  What do I do so that this won't happen?  I feel like something is wrong.  I have heard Macs don't get viruses, but I still have Norton Virus Protection.  What is this and how do I make it not do it again!
    On another note, my trash can all of the sudden started asking for my password when I move something to it.  It is extremely annoying when I want to delete more than one thing.  Is there a way to make that not happen too?    Thank ya'll!

    1. Triple-click the line below to select it:
    ~/.Trash
    2. Right-click or control-click the highlighted line and select
    Services ▹ Show Info
    from the contextual menu.* An Info dialog should open.
    3. The dialog should show "You can read and write" in the Sharing & Permissions section. If that's not what it shows, click the padlock icon in the lower right corner of the window and enter your password when prompted. Use the plus- and minus-sign buttons to give yourself Read & Write access and "everyone" No Access. Delete any other entries in the access list.
    4. In the General section, uncheck the box marked Locked if it's checked.
    5. From the action menu (gear icon) at the bottom of the dialog, select Apply to enclosed items and confirm.
    6. Close the Info window and test.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.
    Remove the Norton/Symantec product by following the instructions on either of these pages:
    Uninstalling your Norton product for Mac
    Removing Symantec programs for Macintosh
    If you have a different version of the product, the procedure may be different. Back up all data before making any changes.
    From the Safari menu bar, select
    Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. Consider installing an ad-blocker and/or a selective cookie block such as the "Ghostery" Safari extension.
