    Click here and follow the instructions. If the computer originally shipped with Mac OS X 10.6.8 or earlier, when you reach step 5, insert its original disk, restart with the C key held down, use the Disk Utility to erase the internal drive, and install a fresh OS.

  • How do I reboot my Macbook Pro back to its original factory settings on all fronts

    I am finishing college and want to wipe my Macbook Clean, delete everything and start over, any one have some helping solutions?

    Install or Reinstall Lion/Mountain Lion from Scratch
    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 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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • How can I restore my Macbook Pro to it's original operating system?

    I am giving my old Macbook Pro to my mother in law and want to restore it back to factory settings. It was originally OSX6 but has been upgraded to OSX 10.8.3. When I try to use the disk that came with it, I get a message that I cannot use that version. Can I reset it to factory settings (wipe out all of my information) while still keeping the latest version of the OS? If not, is there a way to use the disk to restore it back to OSX 6?
    Thank you,

    Welcome to the Apple Support Communities
    OS X Mountain Lion is registered to your Apple and it can only be reinstalled using your Apple ID, so you shouldn't give it to your mother-in-law with Mountain Lion or she will have problems. Instead, reinstall the original Mac OS X version which came with your Mac, in your case, Snow Leopard.
    To restore your Mac to factory settings:
    1. Insert the Mac OS X Install DVD and hold the C key while your computer is starting to start from the DVD.
    2. Choose your language, go to Utilities menu (on the menu bar) > Disk Utility, choose the hard drive at the top of the sidebar, go to Erase tab and erase the drive.
    3. Close Disk Utility and reinstall Mac OS X.
    When the installation finishes, hold the trackpad while your computer is starting to eject the DVD and turn off the computer, so your mother-in-law will be able to set up the computer as she wants. After setting it up, open  > Software Update and install the most recent version, and use the Applications DVD to install iLife apps

  • How do i change an iMovie file back to its original form?

    I have recently made a project on iMovie for my Duke Of Edinburgh challenge. I was trying it out and it was working. But when i tried putting on to youtube, the site told me that it must be a different form i.e. .MOV. so i went and changed it from .rcproject to .MOV and then posted it to youtube. I then deleted it from youtube to try to edit it a bit more; but my laptop went flat. Once I turned my computer back on, I tried opening the project, but it still is not opening. What do I do? Please help me, this project is due in for tomorrow!

  • How do i restore my macbook pro to factory to resell it

    How do I restore my macbook pro to factory to resell it?

    You'll need both gray discs that shipped with your MacBook Pro. If you no longer have them you can (with your serial number handy) order a set from Apple for around $20.
    Then follow the instructions here -> How to prepare your Mac for sale.
    Note that you MUST restore with the original OS that shipped with your Mac!

  • How do I restore my macbook pro to factory setting

    How do I restore my macbook pro to factory setting

    Lion installs both itself and a Recovery HD. Booting the latter is how you reinstall Lion or fix things with Disk Utility. So, what you can do is this:
    Install or Reinstall Lion from Scratch
    If possible backup your files to an external drive or second internal 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.
    Erase the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
    Now, this will completely erase the volume in which Lion is currently installed. When you then reinstall Lion it will be like coming fresh from the factory ready for a new user. I hope this is a working solution for your problem. If it is not, then I would encourage you to create a new topic more relevant to your needs which will solicit others to offer help. That isn't going to happen in someone else's already old topic. Had I not forgotten to stop email notifications from this topic, then I never would have been aware or your post.

    how do i restore my macbook pro to sell it

    Back up the entire system onto an external drive for the last time.
    Locate the original install media that came with the Mac.
    Boot off the media, start up Disk Utility.
    If needed, repartitiion the internal drive to a single partition (i.e., get rid of BootCamp)
    Format the internal drive.
    If paranoid, do a Security Erase of the drive.
    Quit Disk Utility, start the OS X installer
    Install the full OS X with all the trimmings onto the internal drive
    When the install finishes, shut it down. Do not restart, to allow new owner to customize via Setup Assistant.

    I just upgraded my system to Mountain Lion. If I restore my Macbook Pro back to the very beginning state, will the Mountain Lion be removed or not? Thank you

    The only problem that I forsee is that some have reported problems getting machine-specific builds of Lion via Internet Recovery. Not sure if it's working yet or not. But you could give it a shot, I suppose. Basically what you want to do is 'prepare your computer for resale' - just like it came out of the box. Kappy, a pretty wonderful and very knowledgeable man, has tip for that which I have copied and will paste below:
    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.
    Erase the hard drive:
        1.    Select Disk Utility from the main menu and click on the Continue button.
        2.    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
        3.    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
        4.    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Good luck,

  • How do I restore an image back to its original form?

    Is Aperture 3 supposed to be non-destructive? If so, how do I restore an image back to its original form? I'm out of undo's and I need to get rid of some stuff.

    You have a few choices here
    1. The "m" key will show you the master image without adjustments, not remove them;
    2. Right click an image and using the contextual menu, select reset all adjustments, removes them;
    3. Same menu, create new version, allows you to have multiple versions each with unique adjustments, B&W, cropping etc.

  • How do I restore my MacBook Pro to an earlier date?

    I installed an updated version of a program I had been running for over a year now.  I have had a lot of trouble since installing the update, and would like to restore my MacBook Pro to a date that is prior to installing said update.

    However, I see "restoring data".  Will it restore my whole system so that the update to the program is no longer on my computer?  I am interested in restoring the system back to a date before I installed the update.  Data is not an issue for me.

  • How do i restore my MacBook Pro using Time Machine?

    I have a Hard Drive with a Time Machine backup on but i have also other files such as videos, photos, programs etc. I'm just wondering if the other files get deleted if I restore my MacBook Pro? Thx

    Using the Time Machine backup to restore to your Mac will not delete other files you have on the Time Machine backup disk.
    However, in general, it is not a good idea to store live files on a Time Machine backup disk.  The Time Machine disk can fail just like any other disk.  If it does it is no big deal for Time Machine.  You purchase another drive and start another backup.  However if that drive fails, the other files on it will be lost.  So if you offload files onto an extenral drive, they should be on a non-backup drive.  Then go into the Time Machine preferences and make sure that offload drive is not excluded from the list of volumes it will backup.

  • How do I get my MacBook Pro back on after a crash? Error code -2100F, How do I get my MacBook Pro back on after a crash? Error code -2100F

    I have a MacBook Pro bought late 2011. Runs on Mavericks. Recently it became very slow and one day last week while using it, the rainbow cursor spun for over 15 minutes after which it was restarted by pressing the power button. After that, it went directly to OS X Utilities giving me options to
    - Restore from Time Machiine back up (which i do not have),
    - Disk Utility (the message there was "Live System Repair is not supported")
    - Get online help (here)
    - Reinstall OS (but the harddisk is not recognised)
    When attempting to download the recovery file online, the attached picture is the result. (Error code -2100F).
    Please what can be done to restore the Macbook? Wiping it out and losing data is ok with me.

    I suspect that your HDD is the problem. 
    See if you can boot into the recovery partition, OPTION down.  If you can, from the four option menu select Disk Utility. Then run Disk Utility>First Aid, Verify and Repair.
    If that fails, try to boot your MBP OPTION+COMMAND+R which should result in a display with a revolving globe.  This connects your MBP to Apple servers and will install the original OSX that came with the MBP.  Try to repair the HDD first.  You will need a solid Internet connection.
    If no success, then it is a trip to the Apple store genius bar and/or a new HDD.
    Ciao.

  • How do i restore my macbook pro to its out of the box settings?

    Hi folks,
    I recently got a new macbook pro and used Time Machine to import all of my data and settings from my old macbook into my new one. I am now realizing that there is a bunch of stuff on my old hard drive that I don't want on my new one. What I'd like to do is start over -- wipe all of the stuff I've imported onto my new computer so it's fresh and clean again, and then import just some select files -- instead of my entire hard drive. Any suggestions?
    Many thanks!

    First of all, save all the files you want to keep (photos, documents etc.) on a separate drive or in the cloud. Make sure you are connected to the Internet. After that, follow these steps:
    Restart your Mac. Once it restarts and the grey screen appears, press and hold the Command and R keys.
    Select Disk Utility and click Continue.
    Select your startup disk on the left and click the Erase tab.
    Choose Mac OS Extended (Journaled) from the Format menu, enter a name, and then click Erase.
    Select Reinstall OS X, click Continue, and then follow the instructions on your screen.
