    Reinstalling OS X Without Erasing the Drive
    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 and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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.

    Download and install the OS X Yosemite 10.10.3 Combo Update.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • My MacBook Pro will not start up, any suggestions?

    My MacBook Pro will not boot up. I was aware of something odd when I switched it off a couple of hours ago  now when I push the 'on' switch something starts - fans I think, and the little indicator light on the front. Does anyone have any suggestions on how to solve this problem?

    I had the same issue I bought my MacBook Pro in Jan. my harddrive was bad and they had to replace it. I know the guy held down the shift botton for a little then pressed the power botton while still holding down the shift botton and it turned on but not completely since my hard drive was bad.

  • Dowload help queues up but will not start. Any ideas?

    My download helper places a download in the queue but will not start. I have a linux machine and a windows machine they are both doing the samething. A friend who has three computers has the same issue on all three. Any ideas. We have refreashed firefox. Reinstalled download helper and set all the updates. I have set all the conversion points as directed as well.

    See:
    *https://addons.mozilla.org/firefox/addon/video-downloadhelper/

    We have been working for months on a 100% new version which works on Firefox 36+ (it does not work on Firefox 35 and below) and we just released a first test version. If you want to test this version and provide feedback on it, please follow this link.</blockquote>

  • I have just replaced my mac mini because previous motherboard was damaged. I want to pair with my existing wireless keyboard and mouse but can only pair with thebold mac mini which will not start. Any ideas?

    See title. How do I unpair a wireless keyboard and mouse when the previous paired mac mini is damaged and will not start?

    You should be able to go to System Preferences -> Keyboard and System Preferences -> Mouse and discover the bluetooth devices.
    Also, do you have a bluetooth icon on the top bar of your mac?  Should look sort of like this:
    If you can figure out which device is which (by trial and error, if nothing else), you can connect to them on this menu.

  • HT201412 My iPad will not boot up, has a think logo running but will not start. Any ideas?

    Try DFU Mode Restore. Open iTunes on computer, connect iPhone to computer. Hold both Home and Power buttons for exactly 10 seconds, release Power button, keep holding Home button until iTunes recognizes iPhone in Recovery Mode. Usually about 20 seconds time. Restore iPhone Firmware.

  • Mavericks was fine for a while but now it will not start up, any ideas please?

    I get a white screen with apple logo, revolving disc and bar. once the bar reaches the end the MacPro switches off. ican do a safe start, the HD appears to be OK so I have tried to re install Mavericks but I get as far as selecting disk , the alternatives are HD and startup but both are locked. There is anEPI disk but that needs journaling via Utilities which does not seem to work. Where am I going wrong? Has anyone else had this problem?
    I upgraded from Snow Leopard.
    Thanks for that
    TA

    Thank you I have just tried this and after the attempted repair, I got an error and alert message that Live file system repair is not supported. Tried to repair the HD, volume was repaired, it stopped at Boot with the message: disk Utility can't repair this disk back up files, reformat disk and restore files. I guess this my answer.
    Thank you for your help

  • My macbook air will not switch on any ideas - how much is the support calls for a one off??

    I cannot switch on my Macbook Air - It has power to it and it is warm under it - but nothing on the screen and pressing the turn on switch has no effect.  Could it be the battery??  The screen?? or what - very annoying as it has only just had its warranty expired.  I have been on to support and they want to charge me for the call - but how much??does anyone know the answers to my questions please xx

    Take it to an Apple vendor/retailer to arrange for repair.

    Thanks for the help. I didn't know how to do a safe boot. It allowed me to get into disk utility and that sorted it out.

  • My MacBook Pro will not start. When I started it goes to a gray screen with the Apple logo and has the spinning dial. When I started in safe mode it will not start. In safe mode it as an error message that says MacBook Launch_msg():Socket is not connected

    If running 10.7 or later hold down Command-R at Startup.
    This should invoke recovery Mode.
    Choose Disk Utility.
    Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
    Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
    If errors, run again until it comes clean or gets stuck.
    Report any error messages.

  • My MacBook Pro will not start up after entering correct password.

    My MacBook Pro will not start up after entering password.  Circle with an X in it and 'cancel' below it is on bottom of screen.  When clicking on cancel, nothing happens.  This just started last night.  

    Hi MJTOOTS,
    Since you are getting to the login screen, it is booting past the "gray screen" phase, so try the steps in this article, like a Safe Boot.

  • MacBook pro, will not start up- drive begins

    MacBook pro, will not start up- drive begins?

    OK, then try this:
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Since you can boot into safe mode successfully, I'm assuming the problem may be with a bad third-party extension or plug-in (such as a driver for third-party hardware or a bad Flash plug-in, for example.) It can also be a problem with a bad cache or preference file. If the above doesn't help then use a utility like Lion Cache Cleaner 6.0.5, Cocktail, TinkerTool Sys..., or OnyX to clean out user, system, and font caches.

    Actually it sometimes gets a little further, the display will dim and the pointer will appear and then whoop it will turn off. if i do a verbose start up, it will finish all the steps, the white screen will appear and dim and then it will turn off.
