Mac Air starts do not normally

Hello, my starts Air as usual, then what seems like install header lines appear and then the screen stops as if it is trying to install.  Screen starts then the passage of this blue screen lines screen and back, won't go further.

I am currently downing loading a reinstall of OSX El Capitan to see who will correct this.  I hope that I have given on the device that is needed.

According to your results, El Capitan, you can run Apple Hardware Test to reinstall:

Note that an error free AHT is inconclusive.

If the MBA is still not start correctly, you can try target disk Mode in order to access your data:

  • my computer starts in safemode, if I start it in normal mode it starts bt not functions

    If I start it in normal mode it starts bt no functions, no matter what program do you have

    is not open

    Safe mode is only running with the bare minimum of tasks and processes to start Windows.  Normal mode adds a bunch of other "stuff" to this mixture.  The conclusion is that you have a program or task that is running in Normal mode but does not work in Mode safe which is causing your problem.  General approach to solve problems like this is an iterative process, in which case you disable certain parts of the stuff that runs when you start your computer normally. There is a built-in tool to help with this called 'msconfig' (start-> Run-> "msconfig").  Another tool is "AutoRuns" from Microsoft

    AutoRuns: <> http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx >

    Using msconfig, you must start safe mode, then start in "msconfig".  Start by clicking on "Selective startup" and uncheck "Load Startup items".  Click "OK" and restart your computer normally and see if the problem disappears.  If this is the case, relaunch msconfig, click on the "Startup" tab and start allowing items by touches with a reboot inbetween.  If this does not resolve your problem, try unchecking the "Load System Services" tab and repeat.  The General procedure is described here:

    "How to solve configuration errors by using the System Configuration utility in Windows XP"

  • Photo very slow download on iCloud drive, Mac Air 2009, El Capitan

    I hope someone can help... I installed El Capitan on my Mac Air since end 2009 and since improved Air and iPads to iCloud by car. Are my approximately 9000 pictures on Mac Air download at a speed of max 50 per hour. Also I don't see any files or folders in the Finder/iCloud drive. Something clearly happened because my network has significantly slowed down. Is this normal?

    Thanks in advance!

    You synchronize these photos with your iCloud photo library?

    If so, you won't see them in your iCloud drive. The library and iCloud drive are 2 separate areas.

    Don't you have optimize activated? It takes much more time for a large library like yours.

    Your download speed depends on your wifi. It is generally not as fast for most users as the download speed.

  • The applications listed under Launchpad, is there a way I can delete the ones I don't use on my MAC Air?

    The applications listed under Launchpad, is there a way I can delete the ones I don't use on my MAC Air? I hope that I can free up space.

    Start the LaunchPad and hold the option key. The icons will start to shake and an X will appear in the upper corner of some but not all. Click the X to remove the application. Programs that have an X are only purchased/downloaded from the App Store. Integrated programs in Mac OS (like Safari) or programs you have downloaded/purchased elsewhere will not be a X. You should not delete (or move) programs such as Safari and Mail (built-in programs) because the update from Apple guess they were be on your computer in their installation location. Weird things happen if they are moved or deleted.

    Programs you don't purchase/download from the App Store can be deleted without the help of the dashboard, but you must be careful about this. Third party programs can be installed in different ways: some come in disk images and are trained in your application forms. These can be moved without danger in the trash. Some are installed using an installation program, and these require a little care to remove. In some cases, they set up items in addition to the program and require a special uninstall program, but this is not true in all cases. I always do the note of programs using a Setup program, so I can make sure I have properly uninstall.

  • IPad 2 Air screen does not intermittently not

    I have an iPad 2 air with ios9.1 installed. Every so often, the response of the screen for faucets and slides seems to slow down. When I slide across the screen I can see that what really happens is that the iPad I'm removing my finger for a slide becomes a series of notches, as if I'm lifting my finger on the screen. If I type, sometimes I type a letter twice to get the press to register. The only way to the iPad back to normal is a reset, holding the power and home buttons until the Apple logo appears.

    Any other experiences of similar symptoms?

    Hi Madrilleno,

    Please visit Apple support communities.

    It looks like the touchscreen on your iPad that 2 Air is always not responding as it should. To troubleshoot, start with these tips If the screen of your iPhone, iPad or iPod touch does not respond to the touch:

    Check your touch screen

    Make sure your hands are clean and dry, then try the following steps:

    1. If you have a case or a protective screen on your device, try removing it.
    2. Clean the screen with a soft, slightly damp, lint cloth.
    3. Unplug your unit.
    4. Restart your device. If you are unable to restart it, you can force restart your device.

    If your touch screen is still unresponsive as it should, contact the Support technique Apple or make your tablet in an Apple Store or Apple authorized service provider.

    Best regards.

  • IntelHD chips in MacBook Air start just less efficient?

    So I have a Core i5 MBA. 4 GB RAM, 128 GB SSD, and it is probably the strangest machine I've ever owned.

    Speakers just didn't work at all until yesterday when like magic, it started working, which - as a technician 16 - who actually me mystified but little matter... audio works now, so I do not take it any further.

    The problem, for that I'm here, it's that it's all around slow. Moving in the dock, the magnification is extremely agitated, scrolling is jerky, move the mouse happens to a framerate so poor that I'd swear I was on an old Compaq to 20 year.

    To tell the experience that I have-it feels like any Windows machine would be if it was freshly restored without the graphics drivers... except on a Windows machine, I can just track down the hardware of the device ID, find the graphics driver and everything is smooth again... but I'm not too well versed in the language of Macish. What I did the research, the graphics for my Intel HD3000 machine driver is bundled with updates so that it seems that I must rely on kext tools at the terminal to * maybe * trigger my graphic extension.

    None of this seems lead me anywhere I tried internet replicated several times, followed with every update available 10.7 has access to... and evidence of pages of search results at least 15 of things without success. Everything that happens seems also my brick machine, if I try to upgrade to El Capitan on the App Store. Tested the SSD to see if this might be the culprit, checked everything very well. I think that the integrated gfx would mean that if my gfx card was dead, I wouldn't be able to pass material Diagnostics (or even put on with success).

    Only thing I have not tried until now becomes the DMG for ElCapitan and create a bootable disc see if the last just quick MacOSX solves everything (that I'll do tonight).

    If that gets me nowhere... What could be the problem?

  • Mac Air Hardrive bust after 20 months

    I got a MacBook Air in October of 2014. Since then, I was using it and always close after use. I went to turn on my Mac, and it does not turn on. So I went to an Apple store and they said that my Hardrive was broken (remember only 20 months of use) and that it would cost at least $1,000 to repair. Any other use Air have this problem? Oddly, the cost of the repairs is birtually the cost of a new.

    Same problem, very annoying and expensive!

  • Console shows "com.teamviewer" running on my Mac, but I do not have Team Viewer installed

    Because of the constant crashing and having to restart my Mac like 5-6 times a day, I checked the first Console of my Mac. I do NOT understand the programming language, but still I find it disturbing to find what seems like Team Viewer running on my computer, while I have not installed this application. I searched through my Mac, but I found no evidence of this request.

    Here is a part of the text in the Console (I think!) Watch Team Viewer running:

    com Apple.XPC.launchd: (com.teamviewer.service [500]) Service has not been initialized: cannot set the current working directory. error = 2: no file or directory, the path = /Applications/TeamViewer.app/Contents/MacOS: 15F34: spcproxy + 12068 [1343] [F7717708-ACF7-307D-B04E-998DFC36598F]: 0x2

    com Apple.XPC.launchd: (com.teamviewer.service [500]) Service worked only for 0 seconds. Push the respawn in 10 seconds.

    This message seems to be repeated 3 times before being interrupted by other texts from the Console.

    I would like to know what this means and what I need to do to keep my Mac "clean".

    This means that you (or someone else using the computer) tried to remove "TeamViewer" by removing the application that does not work.

    Any third party software that is not installed on the App Store or by drag-and - drop in the Applications folder and uninstall by drag - move to the trash, is a modification of the system.

    Whenever you delete changes to the system, they must be eliminated completely, and the only way to do this is to use the uninstall tool, if any, provided by the developers, or follow their instructions. If the software has been removed incompletely, you may redownload or reinstall even to finish the job.

    I never install modifications of the system myself, and except as stated in this comment, I do not know how to uninstall them. You'll have to do your own research to find this information.

    Here are some general guidelines to help you get started. Suppose you want to remove the so-called "BrickMyMac" (a hypothetical example). First of all, menu using the product, check if there is one, for instructions. Not finding here, look at the Web site, let's say www.brickmymac.com. (Maybe it's not the name real site, if necessary, search the Web for the name of the product). If you don't find anything on the Web site or in your search, contact the developer. While you are waiting for a response, download BrickMyMac.dmg and open it. There may be a request here as "Uninstall BrickMyMac." If this is not the case, open "BrickMyMac.pkg" and look for an uninstall button. The uninstall program can also accessible by clicking on the button customize, when one exists.

    Back up all data before making any changes.

    Generally, you will need to restart the computer in order to perform an uninstall. Until you do this, there may be no effect, or the unpredictable effects.

    If you can't remove the software in any other way, you will have to erase and install OS X. Never install any third party software, unless you're sure you know how to uninstall in the contrary case, it can create problems which are very difficult to solve.

    Try to remove the complex system of changes by hunting for files by name, often will not work and can make the problem worse. The same goes for 'utilities' as the 'AppCleaner"designed to remove software.
