    I installed a update on my Mac book pro, now when I try to start it, it'll come up with the apple logo and a loading bar below it, gets to about 1/4th and shuts down every time.

  • Mac book pro won't start after latest osx update

    Just keeps re-booting showing progress bar. After recent java/iTunes update the Mac book pro restarted and wouldn't shut down. So I powered it down. Anybody that could tell me how to roll back to latest successful startup?
    Thanks

  • Mac Book Pro won't start from hard drive when turned on

    I have a new 15 in Mac Book Pro with 10.8.1. When I turn it on it always boots to the disk utilities rather than my harddrive. I select my startup disk and reboot. It starts fine. But when I shut it off the same sequence repeats. I have verified my drive and selected the hard drive as my startup disk.
    What is happeneing? What should I try?

  • Mac Book Pro won't start

    My mac won't start. Even when I start with option and click recovery hd a grey screen with apple logo comes and nothing else. I started in single user mode and checked that disk is ok. Still not starting up. It happened after sudden slowing down of mac

    Then your drive is OK, but you no longer have a partitioned volume. Do this:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet
                if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.

  • Mac Book Pro won't start up.

    My friend's Macbook pro (probably 2011) hasn't been used for a month. When he turned it on, it got stuck on the gray screen with the logo and spinning wheel. I have tried doing all of the solutions that relate to this problem except for re dowloading the OS, which I can't do because the disk reader is broken.
    It has been on the start up screen for more than an hour and does not seem to be doing anything
    also, after force-shutting it down...when I restart it, there is a loading bar that dissappears after about 5 seconds. It doesn't fill up.
    there is nothing attatched to it, so there shouldn't be any problem with the peripherals.
    When running the safeboot, it says that there is a runtime corruption. I refuse to take the computer to the applestore because it is past the two year warrantee....

    The fact the DVD drive is broken says there are greater problems.  Bring it in for service.

  • My brand new mac book pro, which I've only turned on about 20 times since I purchased it, start making a loud constant clicking noise today -- it sounded like a combination of a computer notification tone and a weird druming sound.  What's the problem?

    Is this thing a piece of junk?  My MacBook Air is running fine.  I've literally only charged the MacBook Pro battery a handful of times -- it's brand new.

    At these prices don't screw around.  Just call applecare to arrange an appointment at the nearest apple store. 
    Alternatively post in the Macbook Pro forum.  This is the Mac Pro forum.

    It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.
    Please describe in detail all you have attempted to do in order to resolve the issue.  Contacted Canon's tech support for instance?
