Tried to update Mac book pro to maverick now system will not boot

I downloaded the maverick update but something happened during the update and now my Mac book pro will not boot into the os.  What should I do?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches. 
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Mac Book Pro (OS 10.4.11) WILL NOT SHUT DOWN UNLESS FORCED! HELP!!!

    My Mac Book Pro 15", 2.33 GHz, 3 GB memory - runninfg Mac OS X 10.4.11 WILL NOT SHUT DOWN UNLESS FORCED! HELP!!!
    When I use the SHUT DOWN command in the Apple Menu - programs close, the screen goes to a blue screen with a revolving time indicator and then remains that way until I FORCE SHUT DOWN by pressing the power button - then after a it makes the sound the screen goes black. I have restarted the machine several times and run disk doctor from the start up disk - no problems are recognized. The problem started last night. I upgraded to Mac OS 10.4.11 today - hoping that the update would resolve the issue - NO LUCK! I keep trying to get a successful SHUT DOWN from the apple command - However I have not been able to get it to SHUT DOWN without forcing the power button. HELP!

    "... and run disk doctor from the start up disk"
    Please explain that one. Disk Doctor was part of Norton Utilities. NU is not supported by OSX and the faster you get rid of it the better. Boot from your Installer disk and run Repair Disk from Disk Utilities. An optional way of shutting down is holding down control-option-command keys and pressing the eject button. When you are having problems address the problem. Upgrading to a new OS version will not solve the problem.
    Wht you should try is running the 10.4.11 intel combo updater here:

  • Mac Book Pro has blinking folder and will not start.

    MY Mac Book Pro mid 2010 has the blinking folder and is froze, I have entered into the Internet recovery mode and tried to reinstall OSX system.  And in the Disk Utility there is no hard drive to select.   What is the next step?  

    Question (?) Mark, Blinking Folder, or Gray Screen at Startup
    These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
    A flashing question mark appears when you start your Mac
    Mac OS X- Gray screen appears during startup
    In most cases the problems may be caused by one or more of these:
    a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
    b. Boot drive's directory has been corrupted - Repair with Disk Utility.
    c. Critical system files are damaged or deleted - Reinstall OS X.
    d. The disk drive is physically non-functional - Replace the hard drive.
    Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
    Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
    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.
    The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
    Reinstall Snow Leopard Without Erasing The drive
    1. 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.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    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.

    Hey, Mac geniuses and wizards - what is going wrong with my macboo

    Have you ever waited and let it do it's thing? I was ready to force mine to quit the other day after waiting 2-3 minutes, and all of sudden, it shut down. I restarted it and then shut it down again. This time it was normal.
    Try this yet before doing an Archive and Install.
    1. Boot from your system CD, run Disk First Aid from your Disk Utility and repair your permissions.
    2. Use a utility like Onyx to clean your system cache out, including your kernel cache. The computer will restart slow right after that, but I keep rebooting the computer about 3 times in a row, and I'm back up to speed.

  • I tried to install latest OS update. Recd error installing. IT tried to load the upgrade in Safe Mode. Now system will not boot up. IT says I have to do a clean install which loses all data.

    After receiving an error when I try to install the latest update of OS-X, I took my laptop to oour schools IT dept. They tried to run the update in safe mode and then they got an error saying the system could not find the hard drive. Now they want to run a clean install which loses 1000's of docs and pictures. I have Block I exams in med school next Monday and all of my notes and slides are on that hard drive.
    The IT dept took the hard drive out and tried to back it up and they said they other computer could not connect or find my hard drive.
    Major panic....
    I have Norton antivirus and have never found any viruses on the system. I also have a program called ExamSoft which some other students here have noted they had similar crashes. Not sure if that is the issue...

    Several take home messages here:
    always back up before you update.
    always back up anything you don't want to lose. Kind of like flossing. Only floss the teeth you don't want to lose.
    Norton is very, very bad software, and you should get rid of it.
    You don't need antivirus software on your mac. Antivirus software on macs causes more trouble than it is worth.
    Your hard drive may be failing and thus may not be salvageable.
    You could try booting into the recovery partition and seeing if you can repair your hard drive.
    If that doesn't work, then there is a small chance that a third party utility (like Disk Warrior or TechTool) might be able to fix your drive (if it is not failing).
    If that doesn't work, you may be able to send your drive and a lot of cash to a drive recovery service and see if they can get your files off it.
    In the mean time, get notes and slides from a (smart) friend.

    Hi, I have a mac book pro running mavericks and recently tried to connect to a 3rd gen apple tv but the airplay icon is not showing up in the top bar. I then tried my girlfriends laptop running mountain lion and it showed up straight away. Any suggestions?

    How old is the MacBook Pro?  AirPlay is only supported on 2011 and newer models, due to the requirements it has in hardware for graphics acceleration.

  • I have a Mac book pro that is giving me the note that it is full.... Trying to back it up...... It's freezing

    Recovering Disk Space
    If you have less than 10 GB you definitely need to delete or offload some files or purchase a lager disk or SSD (see below).  You may want to maintain at least 20 GB of free space so when your disk starts filling again it will have some room before it hits that 10 GB mark again.  More headroom is better.  If you let the space fall much below 9 GB you might not be able to boot your machine.
    Initial easy steps to gain disk space:
    - Delete all files in the Downloads folder.
      Empty the Trash.
    - Start iPhoto.
      Empty its trash.
      Restart.
    - Restart in Safe Mode:
      Restart the computer.
      As soon as you hear the chime press and hold the right shift key.
      Be patient. Hold it down until you see the Apple icon.
      Empty the trash.
      Restart in normal mode.
    - Delete "Recovered Messages", if any.
        Hold the option key down and click "Go" menu in the Finder menu bar.
        Select "Library" from the drop down menu.
        Library > Mail > V2 > Mailboxes
        Delete "Recovered Messages", if any.
    - Empty the Trash.
    - Restart.
    - Re-index your system disk (Macintosh HD):

    Additional reference on freeing disk space:
    http://pondini.org/OSX/DiskSpace.html
    How much disk space is available now?
    Normally you should backup before proceeding to delete other files but at this point it may not be possible.  Having taken the steps above will the backup compete now?  If not, stop, post back, for emergency data protection procedures and/or how to free more disk space.

    Assuming that you tried to install Win 7 in bootcamp.
    Power on the machine and press and hold the "option" key when you hear the bong sound.
    Select the Macintosh HD icon and press "return" or just click on the icon.
    Once booted into OS X go to System Preferences and select the Startup Disk icon and configure startup to use the Macintosh HD.
