    Shift key is stuck.
    Do you have a spare usb keyboard? if so, use it until you can take the computer to the Apple store to have it fixed.
    Best.

  • Mac Book Pro Restarts automatically

    My mac book pro hangs for few seconds and then restarts. This problem has started after I have upgraded to OS X Yosemite. Please fix this.

    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. Click Utilities, then Console in the icon grid.
    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.
    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.

  • Mac book air restart lost all my settings

    My mac book restarted itself and now its back to the default settings. All my info is gone. What happened and how do I fix it?

    If all your files are missing
    You may have logged in as a different user, such as Guest. Open the Users & Groups pane in System Preferences. Your name should be at the top of the user list, under Current User. See also this support article.
    If files are missing from one folder
    Change the Finder view mode; for example, from icon view to list view, or vice versa.
    If files are present, but seem outdated
    You may have started up from a different volume (disk.) Open the Startup Disk preference pane and check the selection.

  • Can i get the time capsule to automatically back up my file from my Mac Book Air but have certain files which are only stored on the time capsule and not the computer? Then can i access these files only on the time capsule without connecting it?

    You can, but how are you going to back up those other files?  When (not if) your Time Capsule fails, you risk losing them.  See #Q3 in Using Time Machine with a Time Capsule for details.
    Then can i access these files only on the time capsule without connecting it?
    Not sure what you mean.  You have to connect a computer, either via Ethernet cable or wirelessly, to read or write to the disk. 

  • I'm downloading the OS X Mavericks then in the process of downloading till 4.20GB it stops and shut down my Mac Book Pro and automatically restarted

    i'm downloading the OS X Mavericks then in the process of downloading till 4.20GB it stops and shut down my Mac Book Pro and automatically restarted. Any answers for this?

    The download is over 5GB's so yours is incomplete.
    You should be able to resume the download (instead of starting over) at the App Store.

  • How can I remove iCloud from my Mac Book and iPad and Mac Book Air and then just reload back on the MB Air and iPad only?

    How can I remove iCloud from my Mac Book and iPad and Mac Book Air and then just reload back on the MB Air and iPad only, which have a different user with a separate Apple ID?

    You have quite muddied up the waters, I'm afraid. Assuming you now have a single GUID partition formatted Mac OS Extended, Journaled, you should try reinstalling Lion:
    Reinstalling Lion/Mountain Lion 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 Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion 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.

  • HT4199 i can t mirror my mac book air via apple tv.

    i bought apple tv 3rd generation and have a mac book air from mid 2012. i have problems mirroring my mac to aplle tv. there is now morroring icon.
    how can i set that up ?

    First, uninstall Clean My Mac. Third party so called Mac cleaning utilities can do far more harm than good. Your Mac runs maintenance for you in the background.
    http://macpaw.com/knowledgebase/cleanmymac/how_to_uninstall_cleanmymac
    Restart your Mac after you have uninstalled Clean My Mac.
    Hopefully you have a backup of your Bookmarks so then can be reimported back into Safari ..

  • I have a 2nd gen Mac book air with Lion. The hard disk has filled up even though i keep my data , music etc on hard drive . I used disk inspector to find where problem was and it is 20GB in the hidden files under the user directory can i resolve this ?

    I have a 2nd Gen MAc book Air with Lion .  The 60GB hard disc has quickly filled up despite me keeping most of my data on a portable hard drive .  I used disk inspector to locate the problem but found that it was was in 20 GB of hidden files in my user directory .  Is this correct and is there anything i can do about it ? Using disk inspector you can not see individual hudden diretories or files. I did unhide them but there is a mass of diretories etc and so no way i could see if this is one or multiple files using the space. Library System and  Applications are at 4 3 and 3 GB respectvely.  The data I actually keep on there is 9GB    Thanks for any help

    I think the problem is Quick Time Player. I am using OS 10.6.8 by the way.
    I tried it out again.
    I had about 26 GB of space before I played an .avi video.
    After the movie started to play (it was slow to load), I got a warning message that my startup disk was full. I opened Disk Utility and it told me I had no space left (about 20 MB or something like that was left).
    I watched to the end of the movie.
    Then I quit Quicktime Player.
    And I shut down the computer.
    I turned on the computer and checked Disk Utility. I have about 26 GB of space.
    I think for some reason Quicktime Player uses up a lot of the disk space when it runs movies that are problematic. This movie I was watching did not open with vlc.
    I normally use vlc to watch movies.
    Probably it doesn't use up this much space when the movie is OK.
    I think there's a problem with this particular movie. It is about 50 MB so it's not that big a file. I watch .smi subtitles with it. The Quicktime Player automatically loads the subtitle file in this case because the subtitle file has the same name as the movie file.
    I watched about 10 movie files from the same series that I downloaded together and did not have any problem watching them. I watched them on vlc. But this latest movie had problems I think (as I repeat). It did not load on vlc even though I waited for a minute, and normally movies load instantly on vlc. 
    So I think that movie file caused problems. It made QT player use up a lot of hard disk space.
    I had better avoid watching that movie in the future. I don't want it to wreck my hard drive.
    So to sum up, everything is back to normal. I have the hard disk space that I should have. However, I am scared of damaging my hard drive due to shonky movie files that eat up all the space when they are played using QT player, and so I will not watch those files in the future, as I do not know why the files do that.

  • Erase mac book air content

    How do you erase content of mac book air and bring it back to factory settings

    http://support.apple.com/kb/HT4718
    OS X Lion or OS X Mountain Lion includes a built in set of utilities in the Recovery System. Restart your Mac and hold down the Command key and the R key (Command-R), and keep holding them until the Apple icon appears, indicating that your Mac is starting up. After the Recovery System is finished starting up, you should see a desktop with a OS X menu bar and a "Mac OS X Utilities" application window. Note: If you see a login window or your own desktop and icons, it is possible that you didn't hold Command-R early enough. Restart and try again.
    In order to reinstall OS X Lion or OS X Mountain Lion, you will need to be connected to an Ethernet or Wi-Fi network. The Wi-Fi menu item is in the upper-right corner of the screen. Click the icon to display all available Wi-Fi networks. Click your preferred network name and, if needed, enter a username and/or password.

  • My mac book air has a virus which is creating a lot of issues...how do i get rid of it? is there a free software to detect it and remove it?

    my mac book air has a virus which is creating a lot of issues...how do i get rid of it? is there a free software to detect it and remove it?

    There is no need to download anything to solve this problem.
    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • My mac book air turn on with grey apple icon and spining wheel. then it wont turn off.

    my mac book air turn on with grey apple icon and spining wheel. then it wont turn off.pls help

    Have exactly the same problem with my wife's MacBook Air. After restaring in Restore mode and trying to repair the disk (Disk Utility showed errors in the verification), the system tells me to backup as much data as possible (how?), re-format the disk and restore backed-up files. Error comes up when "updating boot support partitions for the volume as required".
    Original restart action was done due to software update requesting it, if I remember correctly, iTunes was updated.
    I don't want to start a painful back-up procedure (although I do regular back-ups): how should I know, where iPhoto stores it's data or where my mails are (yes, still using local mail)? How can I access the data if I can't boot?
    My iMac's disk crashed also a couple of months ago and I'm still recovering. I have four Apple devices, two of them have failed. Can Apple afford such a ratio?
