    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 to reset my macbook pro late 2011

    I have a late 2011 macbook pro that i installed mountain lion when i got it, it orginally had snow leopard. I have the iLife CD and the Mac OS X install DVD but when i put the cd in it says "You cant use this version of the application "install Mac OS X" with this verion of OS X. you have "Install Mac OS X" 23.1.1. If anyone knows what i have to do to reset my macbook pro to factory settings please tell me. I would like a answer ASAP.

    In that case, you don't have a Late 2011 MacBook Pro, as they came with Lion, not with Snow Leopard. This message appears because you are trying to reinstall Snow Leopard while you are running Lion or a newer Mac OS X version.
    To restore the MacBook Pro to factory settings:
    1. Make a backup of your files.
    2. Insert the Mac OS X disc and hold the C key while your Mac is starting to start up from the disc.
    3. Go to Utilities menu (on the menu bar) > Disk Utility, and erase the drive > http://pondini.org/OSX/DU1.html If you are going to sell the Mac, consider using a secure erase option.
    4. Close Disk Utility and reinstall OS X.
    5. Insert the Applications disc and install iLife apps.
    6. Open  > Software Update, and install the most recent version.
    If you are going to sell the Mac, ignore the steps 5 and 6, and turn off the Mac when the installation is completed.

    how to reset macbook pro to factory setting?

    To restore your computer to factory settings:
    1. Hold Command and R keys while your Mac is starting to start into OS X Recovery, and open Disk Utility.
    2. Select "Macintosh HD" in the sidebar, go to Erase tab and erase the disk.
    3. Close Disk Utility and reinstall OS X.
    After reinstalling OS X, you will have to reinstall your iLife applications. If your Mac came with DVDs, just insert the Applications disc and install them. If your Mac didn't come with DVDs, open App Store > Purchases, and download the iLife applications

  • HOW TO RESET MY MACBOOK PRO MD976 AS I WANT TO DELETE ALL DATA FROM MACBOOK

    how do i reset macbook pro MD976 to factory setting ? , cause i want to sell it .

    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
           A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
           B. Clone to an external drive using using Carbon Copy Cloner.
              1. Open Carbon Copy Cloner.
              2. Select the Source volume from the Select a source drop down menu on the left side.
              3. Select the Destination volume from the Select a destination drop down menu on the right
                  side.
              4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
                  sure to opt for that.
                   Destination means a freshly erased external backup drive. Source means the internal
                   startup drive.
    Step Two - Prepare the machine for the new buyer:
              1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
              2, Remove any Open Firmware passwords or Firmware passwords.
              3. Turn the brightness full up and volume nearly so.
              4. Turn off File Vault, if enabled.
              5. Disable iCloud, if enabled: See What to do with iCloud before selling your computer.
    Step Three - Install a fresh OS:
         A. Snow Leopard and earlier versions of OS X
              1. Insert the original OS X install CD/DVD that came with your computer.
              2. Restart the computer while holding down the C key to boot from the CD/DVD.
              3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
                  Optionally, click on the Security button and set the Zero Data option to one-pass.
              4. Install OS X.
              5. Upon completion DO NOT restart the computer.
              6. Shutdown the computer.
         B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
             Note: You will need an active Internet connection. I suggest using Ethernet if possible because
                       it is three times faster than wireless.
              1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
                  Utilities window appears.
              2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
              3. 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.
              4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
                  and set the Zero Data option to one-pass.
              5. Click on the Erase button and wait until the process has completed.
              6. Quit DU and return to the Mac OS X Utilities window.
              7. Select Reinstall Lion/Mountain Lion and click on the Install button.
              8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

  • How to reset my MacBook Pro for re-sale

    I'm thinking of selling my 2010 MacBook Pro, which I bought with OS X 10.6 Snow Leopard. When selling previous Macs, I've deleted everything, including other user accounts and then re-installed the OS from the supplied CDs or DVD. This then leaves a new and pristine condition for the new owner to set-up as required.
    However, I'm currently using Lion, which is not available on a disk. So my question is, how do I get back to a new version of Lion ready for my Mac's new owner to set-up as their own?
    I've read on these forums about booting and holding down the Alt key in order to boot from the Restore partition, which hopefully has a bootable copy of Lion. Other threads suggest that I should Show Package Contents of the downloaded Lion file and burn the DMG to a DVD using Disc Utility. I guess that this will produce a software update disc and that the new owner will still need to boot initially with the Snow Leopard disc and follow the software updates until a point is reached whereby the new Lion disc will work.
    I want to sell this as having OS X 10.7.3 Lion - I've paid for the upgrade and wish to pass this to the new owner.
    Any thoughts or advice gratefully received.

    The other person can do illegal things on your old machine or worst set you up. Which you will have to hire a computer specialist to prove your innocence, if there is evidence to be found, one simple mistake of missed evidence and you could be in serious trouble, fighting your case from a prison cell hoping to get a retrial.
    When you erase the drive from the 10.6 disk, select the entire internal drive on a far left, not the slightly indented partition underneath it, and use the Erase with Zero option at least, or 7x for military/government grade erasures.
    https://discussions.apple.com/docs/DOC-3191
    The way technology is recording everything we are doing, you can't afford to take any chances, break from your machine, break from it completely. Let them install Lion with their AppleID, then they won't have any trouble updating to 10.8 or even 10.9., getting redownloads if they need it.

  • How to connect a MacBook Pro to internet with no cable, no Wifi, no ADSL?

    I'll need to connect my MacBook Pro to internet in an environment without any of the above mentioned means.
    1. What are the possibilities? GSM (mobile phone), a modem (express card?)?
    2. Where can I find the information on how to proceed?
    Thanks!

    Hello,
    You can use a mobile phone as a modem. This can be done manually by yourself or automatic by a commercial third party software:
    Manual: you need the right scripts and connection settings and enter them manually in your network configurations. You find the right scripts and configuration hints here: http://www.taniwha.org.uk
    Automatic: try the demo of launch2net at http://www.launch2net.com which features a powerful configuration assistant which already includes all necessary network settings and scripts.
    The other option would be to use the XU 870 ExpressCard modem from Novatel at http://www.novatelwireless.com. If you are living in the USA and use Cingular, Apple has released a so called WWAN update with all settings. So you can use this ExpressCard in Cingular networks immediatly.
    Thank you

  • How easily can the MacBook Pro be scratched with another aluminium product?

    I have a MacBook Pro 15' and an iPad 2 with a Smart Cover.  Every now and then, if I carry both in my hands, I stack the iPad on top of the MacBook Pro.  I will hear a sound of metal VS metal and I have figured what it was.  The hinge of the Smart Cover was rubbing against my MBP.  I was wondering, can the 2 scratch each other?  I have noticed wear on the metal Smart Cover hinges, and was wondering if the same thing could happen to my MBP.
    Thanks for helping!

    Aluminum, while flexible and lightweight, is a very soft metal. Apple was very careful with engineering the MBP to round the edges and make the shell as damage proof as possible. Still, with a little bit of hand pressure, you can cut into aluminum with an everyday table knife. That should tell you something.

  • My macbook pro didnt come with an install disk?

    my macbook pro 15inch did not come with an install disk? what should i do?

    Macs which come with 10.7 preinstalled don't include install disks. Everything you need is either on Lion's recovery drive or the web.
