  • How do I reinstall the operating system on my MacBook Pro without using my apple id?

    I'm selling my computer. Everything has been erased. Now the operating system, Lion, needs to be installed. I believe the computer did not come with a cd so reinstalling is done through wifi.

    We bought it in January 2010. I'm not sure what OS it came with but when I look at the dates of each OS on wikipedia it looks like it came with Snow Leopard. The only disk I happen to have is Leopard.
    Let's drop back a minute and go through what you can and cannot do with this machine.
    1.  If the machine came with Leopard, you can install Leopard and then go to Snow Leopard and up the line of the on-line Mac OS X versions, that is, Lion, and Mountain Lion and Mavericks as compatible.  If the disk for Leopard that you have is a grey face disk, that is a machine-specific disk and will only work if it is the disk that came with your MacBook Pro.  If it is a panted face (black) with a large silver X it is a retail version and will install IF your machine came with Leopard.
    2.  If your MacBook Pro came with Snow Leopard, it will not install Leopard.  If it came with Snow Leopard and is a 2010 machine, it will not install the retail version of Snow Leopard since that is 10.6.3 and the 2010 and later machines came with 10.6.6 preinstalled.  You must call Apple Customer Support and have them send you the machine-specific install disk for that machine.  There is a fee of something like $20 in the US for doing that.
    3.  If your machine came with Snow Leopard, you need to reinstall Snow Leopard and then move to the on-line Mac OS X versions, you cannot download a version with your Apple ID associated with the version currently on the machine.  The starting point HAS to be Snow Leopard for the new owner to do an on-line Mac OS X download.
    4.  With Snow Leopard installed and on-line software updated to 10.6.8, the new owner can then move up to Lion or above depending on the compatibility of the hardware.  To move to Lion or above the machine must have an Intel Core 2 Duo processor.  To move to Mountain Lion or Mavericks the machine must meet the requirements in http://support.apple.com/kb/HT5842. 
    At any rate, the new owner must install Snow Leopard on that machine before any move to one of the Mac App Store versions of Mac OS X.

  • HT1338 How do I update the Operating System for my MacBook Pro?

    I currently have OS version 10.5.8.  I can't get the proper plug-ins for Flash anymore because my Mac OS is too old.  I've tried updating the OS, but it will not let me install it.  Any help on this would be greatly appreciated.  Thanks.

    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion — System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
                 Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
             7. Xserve (Early 2009) — Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
    Are my applications compatible?

  • How do I disactivate the operating system on my macbook that was stolen from me?

    So in early September someone who I know broke into my apartment and stole my computer, I called the police and filed a report. I have some very snesitive documents on the computer that I would prefer no one to get their hands on. I was able to find the operating system disk I had purchsed to update the operating system a few years ago so I have all of the information associated with the OS. I do not know the IP address of the computer or exactly where it is (obviously or I would have it back). I want to basically turn the OS off so my files on the computer cannot be opened or used. Is there any way to disactivate the OS remotely like you can with Windows (if you use the product key on another PC it deactivates the previous version). I don't know if it matters but it was a late 2006 macbook (black) model 13" screen.

  • What is the operating system on my MacBook Pro

    I am trying to find out whether I have Lion, Tiger. Leopard etc on my MacBook.  My Mail is configured to appear on my Blackberry phone, which is fine but if I compose an e-mail in Mail on my Macbook it appears several time (up to 50) on my Blackberry which I then have to laboriously have to delete.  My internet provider have asked me to identify what my operating system is but all I can find out is that it is Mac OSX Version 10.6.7.  If anyone has any idea how to rectify this problem it would be helpful as well.
    Many thanks

    Hi Linc, many thanks for your reply, my internet provider told me that there have been a few problems with the new operating system Lion, but I don't have that, they also said that if I hadn't got Lion then I would have to remove the account from my MacBook and set it up again.  When I first got my MacBook a few months ago it did it all for me.  They have given me instructions on how to do this so fingers crossed!!

    Purchased a used macbook pro with Mountain Lion. My old Mac runs Snow Leopard is backed up to Time machine. How do I register the operating system to me and how do I use Time Machine to move my files to the new used computer?

    If you look at the User Tips tab, you will find a write up on just this subject:
    https://discussions.apple.com/docs/DOC-4053
    The subject of buying/selling a Mac is quite complicated.  Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
    SELLING A MAC A
    Internet Recovery, and Transferability of OS & iLife Apps
    Selling an Old Mac:
    • When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
    • Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
    Internet Recovery:
    • In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
    • Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
    iLife Apps:
    • When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
    • Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
    • It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
    SELLING A MAC B
    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 do I take the zoom feature off my MacBook Pro? I have already went to System Preferences and turned "zoom" off in the Universal Access. I saw where someone said to use THREE fingers to double click... ??? Double click what? And 3 fingers?

    Can someone help me?How do I take the zoom feature off my MacBook Pro? I have already went to System Preferences and turned "zoom" off in the Universal Access. I saw where someone said to use THREE fingers to double click... ??? Double click what? And 3 fingers?

    What really cheeses me off here is that Apple isn't allowing users enough customization.  With each update of iTunes (and the OS and iOS) we're forced to give up something that worked well for the way we want to use the app and make do with fewer (and lamer) options.  If Apple keeps this up, they're going to start losing customers fast.  I mean if this isn't fixed soon, I'm pretty sure I'm going to give up on iTunes, and then I'll probably go ahead and get a Galaxy when I need to replace my iPhone.
    What I don't understand about how they won't let users delete the list of available podcasts now is why?  How is this making it a better program?  I can understand that not all users are capable enough to right-click on a feed and select "Show all available episodes", so I can see why they want the complete list to be the default (and, surprise, it already was).  But to not give users the option to delete that list?  It's inconsiderate because it makes navigating feeds with a large back catalogue really frustrating.  I'm flabbergasted that no one at Apple considered all the podcast feeds that keep hundreds of episodes available when they removed this feature.  It smacks of rank incompetence.
    What improvement were they trying to make here anyway?  There was nothing wrong to my mind about how podcasts were managed in previous versions.  Whatever improvement they were trying to make here, they should have realized that many users would at least want the option to keep things the way they were.
    And reverting to a previous version is no solution.  I can't sync my iPhone with the new iOS without this update, and (while I do have some issues--specifically how you can't play podcasts in the Music app anymore) I do like the new iOS.
