HOW CAN I REINSTALL LION

I purchased a used Imac which has OSX Lion installed. The original owner has a password that i can't get. The only discs I have are for 10.6.4 which came with it when new. I would like to do a complete reset back to factory specs but don't know what to do.

Drive Preparation
1. Boot from your OS X 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, 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 (for Intel Macs) or APM (for PPC Macs,) 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.
4. Quit DU and return to the installer. Proceed with the Snow Leopard installation.

  • How can I reinstall Lion on a replacement HD?

    The HD on my Mac Mini [Mid 2009] seemed to be dying.  Disk Utility confirmed that the Drive was on its way out.  So, I did a complete backup to TM, and since the Drive still seemed to be operating, I made a clone of it using Carbon Copy Cloner.
    I had the Drive replaced, and have spent the last two evenings searching for the answer on how to put everything back on my Drive.  I was thinking I needed to reinstall Lion and THEN restore the files from either TM or Carbon Copy Cloner.  The trouble is that the Mini won't boot without Lion [or a predecessor] already installed.
    I THINK I can boot from my external drive -- the one to which I saved the Carbon Copy Cloner backup -- but I'm not sure.  Before trying that, is there a way to reinstall Lion on the Mini?  [Without Snow Leopard on it, I don't have the App Store, so I can't simply D/L Lion again from the App Store.  I saw Apple's KB article which noted: If you happen to encounter a situation in which you cannot start from the Recovery HD, such as your hard drive stopped responding or you installed a new hard drive without Mac OS X installed, new Mac models introduced after public availability of OS X Lion automatically use the Lion Internet Recovery feature if the Recovery HD (Command-R method above) doesn't work. Lion Internet Recovery lets you start your Mac directly from Apple's Servers. The system runs a quick  test of your memory and hard drive to ensure there are no hardware issues.
    Since I "happened" to encounter a situation where I cannot start from the Recovery HD -- and I don't have a "new Mac Model,"  how do I reinstall Lion on my Mini?
    Thanks for your help.

    Thank you for the response.
    That's exactly what I did -- down to the finger crossing.  Unfortunately, no joy --despite the season.
    Despite several other Macs around the house we apparently don't have a Stand Alone copy of Snow Leopard, which would at least let me re-download Lion.  I DID find a boxed Vers. of Leopard, which is how I got the Mini to boot in the first place.
    The Mini will boot off of the external, and all my files appear to be there and working.  But despite having copied it all over to the Mini, it won't boot -- it just hangs at the Gray Boot-up screen.
    This sure would be a lot easier if I hadn't bought Lion off of the App store.  Without discs to work from I'm having a hard time recovering from a dead HD.
    Thank you, again for the help.  Merry Christmas!

  • My iTunes library is missing since upgrade Lion 7.2.  I have it all backed up so that's not the issue. How can I reinstall it with all my hundreds of playlists intact or do I have to recreate each one upon reinstalling the backup copy? Thank you for help

    Almost my iTunes library is missing since upgrade Lion 7.2. (the last 2.5 weeks worth of added music has transferred post-upgrade, none of whcih was bought from iTunes)
    I have it all backed up so that's not the issue. How can I reinstall it with all my hundreds of playlists intact or do I have to recreate each playlist upon reinstalling the backup copy? This would save a HUGE amount of time and efforts. Thank you for your help!

    hi Limnos,
    I do not mean the entire ITunes folder but, rather, the contents of the ITunes folder prior to September 29th.  (90% of the media is missing, along with all playlists)  The media that remains says it was added on 9/29 although I know most of it was added many months or even years earlier. There are no playlists listed at all, before or after 9/29.  (I know for certain that I added non-iTunes purchased songs on 10/6 although I had not created playlists for them)
    I have my iTunes folder backed up on both an external drive as well as Time Machine.
    I run iTunes off of an ITunes folder on my computer rather than from the external, if that's what you mean about how I have it set up. 
    Is it OK to drag the entire iTunes folder from the external drive onto my laptop's drive and see if that fixes it?
    Thank you for your help!

  • How can I reinstall os x lion?

    Due to an unrecoverable error on the data structure of the hard disc with Mac OS X Lion, I had to erase the hard disk and install Mac OS X Snow Leopard from installer CDROM disc. After the installation I restored all data from a security copy saved on an external hard drive with Time Machine. Now I do not remember how to install again OS X Lion, Do I have to download from iTunes?
    The problem is that the iTunes version I have installed is 10.6.3 and is not compatible with OS X Snow Leopard.
    So how can I get Lion reinstalled and from where I have to download it?  (I payed for downloading the update to Lion the first Time)
    Thanks for any help.

    Go to the App Store and re download it. You won't be charged again. The App Store (Mac not iTunes) can be accessed from your Apple menu, or the App Store icon in your Dock, or your Applications folder.
    How to re download apps from the Mac App Store:
    Open the App Store. From the menu bar click Store > Sign In
    Click Purchases from the top of the App Store window.
    Select which apps you want to re download. Then right or control click where you see Installed  then click Install.
    Make sure and use the same Apple ID used for the original purchase.
    Due to an unrecoverable error on the data structure of the hard disc with Mac OS X Lion
    If need to repair the startup disk or reinstall the OS X running Lion, don't use your Snow Leopard install discs. Use OS X Lion: About Lion Recovery
    You can restore from a Time Machine backup using Lion Recovery.

  • While installing Lion my Bluetooth module disappeared. How can I reinstall it?

    While installing Lion my Bluetooth module disappeared. How can I reinstall it?

    You ought to get a dialog asking to install the first time you run an app that needs it
    Details here:
    http://www.macworld.com/article/1167855/installing_mountain_lion_what_you_need_t o_know.html
    The relevant bit is this:
    Note that the first time you try to load a webpage or run an app that requires Java, Mountain Lion will prompt you to download and install the Java runtime, even if you upgraded from Snow Leopard or Lion and you’d previously installed Java. This is normal—you shouldn’t worry that installing Mountain Lion somehow “lost” any of your data or apps.
    Or you can go to the Apple Downloads page and search for Java

  • How can I reinstall Mountain Lion (already bought before) after I restore my MacBook unibody (restores it to snow leopard)?

    Originally I had upgraded my MacBook unibody to mountain and used time machine to back up my data. I then wanted to restore my MacBook so I did but it restored my MacBook to snow leopard. After restoring to an old time machine backup some of the apps aren't compatible because they require mountain lion but my system got restored to snow leopard. How can I reinstall my already purchased mountain lion if snow leopard doesn't have an App Store?

    10.6 Snow Leopard will get the App Store when you update it to 10.6.8. Download the 10.6.8 combo updater to bring it up to 10.6.8. http://support.apple.com/kb/DL1399

    How Can you reinstall Photoshop Elements12 to a computer that its was there but loss it after installing windows 8.1

    Reinstalling Mavericks depends on several factors:
    if you erased your recovery partition
    what OS originally came on your Mac.
    I'll assume you don't have a backup available that you made before your mishap,  because you didn't mention it.
    That's really the take home message here: have a backup!
    If you still have your recovery partition:
    boot into the recovery partition (command R at restart)
    use the recovery partition to reinstall Mavericks. see: OS X: About OS X Recovery
    if you do not still have your recovery partition, then it depends on whether your Mac originally came with installer disks or not.
    If it originally came with installer disks, you would boot from the installer disks, erase your HD, and then reinstall the OS that is on the installer disks, and then upgrade as necessary until you get to Mavericks.
    If your mac did not originally come with installer disks, but you managed to erase your recovery partition, then you can try to boot into internet recovery (option-command-R at restart), and use internet recovery to erase your HD and reinstall the OS that originally came with your computer, and then upgrade to Mavericks if you need to. See: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld
             (the reference refers to ML but it applies just as well to Mavericks).

  • HT1544 how can I reinstall the Mac OS X from scratch?

    I have an early 2008 iMac that came with Mac OS X 10.5 leopard. I have bought all os's since then, and Today I am using the most recent one, mountain lion. My question is, how can I reinstall the Mac OS X from scratch? Is there a quick way ? Or do I have to:
    Find the leopard CDs that came with the iMac
    And go through the cd installation.
    Then, can I jump from leopard to mountain lion?

    If your goal is to just reinstall Mountain Lion, you can restart the computer holding the Command and R keys, then choose the reinstall OS X option from the utilities choices presented to you.
    That restarts the computer using the recovery hard drive that was created when you installed Mountain Lion...but note you must have an internet connection when you do this reinstall.

  • How can I reinstall the App Store?

    I have lost all the programs except safari, how can I reinstall everything?

    Howdy alegarfer97,
    In order to reinstall the applications that are installed as part of the system, you'll need to reinstall OS X. While the article linked below is written for OS X Mavericks (10.9), the steps are the same for Lion (10.7) through Yosemite (10.10).

  • Erased mac book pro (2009), how can i reinstall osx?  it won't recognize any old system disc

    erased mac book pro (2009), how can i reinstall osx?  it won't recognize old system discs

    Did you try:
    Install or Reinstall Mavericks or 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.
    OS X Mavericks- Erase and reinstall OS X
    OS X Mountain Lion- Erase and reinstall OS X
    OS X Lion- Erase and reinstall Mac OS X
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    If you don't have the original discs that came with the computer, then you can install the retail version of 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 Mavericks 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.
