HT1338 how do you perform a clean install for imac

How to perform a clean install for imac, because I cannot upgrade to version 10.6?

Here are the technical requirements for Snow Leopard:
http://support.apple.com/kb/sp575
If your iMac meets the requirements, then you will have to purchase the Snow Leopard disk from apple:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
To reinstall your OS, insert the original OS disk that came with your iMac and start up the iMac holding the C key.  Start the installation process and when you see the menu bar, select 'Utilities'. From the drop down menu, select Disk Utility.  Erase the HDD and the continue the installation.
Note that this will erase all data on the HDD so have it backed up before you start.
Ciao.

  • How do you do a  Clean install lion

    How do you do a clean install of lion? My iMac is 8 yr old and has gotten sluggish. At one point it was suggested that I might want to do a clean install but no one ever told me how to do that since we don't have a disk!

    Assuming you already have Lion installed, boot into Recovery Mode (Command-R). From there you can reinstall Lion. Note, however, that a clean install means you first erase the drive you want to do the clean install on, and unless you have a complete backup of everything that's currently on it, you'll lose it all; the clean install will leave you with a fresh operating system but nothing else. To get it all back, make that external clone, then when the clean install is finished on the internal, Setup Assitant will run and you can point it at the external clone to get all your stuff back.

  • How do I perform a clean install of ios8 on my iPhone 5

    I would like to perform a clean install, meaning not putting ios8 on top of ios7.
    Is there an advantage to doing this? When I installed Mavericks on my MBP I had the Genius Bar do it and it was like a new Mac,
    So, my thoughts are that a clean install, starting as if it were a new phone would be the same.
    Is this true?
    How would I do that after backing up through the latest iTunes.
    Would I need to set up pop mail accounts from scratch or would that come back in the restore backups
    As you can see, I am unsure as to the best way to make my iPhone 5 run trouble free with ios8
    Advice and instructions are welcome

    Okay....so Apple does have a guide related to Mass deployment which includes a rough way to do a clean OS X Server clean install. You need to use a NetBoot Lion Server as a boot, but it works.
    http://support.apple.com/kb/HT4746
    Use these steps to create a NetRestore image of an un-configured Lion Server:
    Install OS X Lion, and then Lion Server. This server will be used to create the NetRestore image.
    On the server, install the app named "Install Mac OS X Lion" from the Mac App Store (a network connection is required for this process).
    Install the Server Admin Tools from http://support.apple.com/downloads/ on the server.
    Open the "Install Mac OS X Lion" application, and install to an empty volume. This volume can be a spare partition or external hard drive. Be sure to click the Customize button and to select the Lion Server software.
    Once installation is complete, the server will restart from the newly installed volume.  Instead of completing the setup assistant, press Command-Q to quit the assistant.
    Select the option to shut the server down.
    Restart the server and hold the Option key.
    When the Startup Manager appears, select the volume which you've already configured Lion Server on.
    Open System Image Utility and create a NetRestore image from the newly installed (and still un-configured) volume. If you'd prefer to image the volume after it has already been configured, you can proceed with the setup assistant before booting back to the original installation created in step 1.

  • So how does one perform a clean install on U310?

    Hello,
    I'm currently annoyed with software that comes pre-installed on the notebook, and would like to perform a clean install of Windows 7. I've got a bootable USB stick prepared, but don't know what to do next. Also, I'd like to install the system on the SSD drive, not on HDD, and don't want to lose warranty.
    Could someone who already did this make a step-by-step guide, or at least provide some hints? Thanks!

  • Could someone help me with instructions for doing a clean install for iMac with mountain lion 10.8.4 ?

       Could someone help me with instructions for doing a clean install for Could someone help me with instructions for doing a clean install for an early 2009 iMac 20"  with Mountain Lion 10.8.4 ?
       Thank You,
                                leetruitt

       Barney,  William,  nbar, Galt\'s Gulch:
       A nephew stayed with us to take a course at the local community college last semester. I allowed him use of my mac for research just after I installed Mountain Lion. He decided to "help out" and ran a 3rd party clean and tune up app., Magician.  The tune up wiped over 1200 titles of my music in iTunes,  also a path of folders with names containing nothing but more empty folders with names. Almost every program I open and run for a short time crashes, also folders and programs are in wrong places, or cannot be located (the nephew, for instance). Up to this time I have always been able to track a problem far enough to resolve it by careful persistence and good luck, but I do not have the tech savvy to solve this one without getting in deeper. I have run disk utility saveral times and always get  variations of this:
    ACL found but not expected on
    "private/etc/resolve.conf"
    "private/etc/raddb/sites-enabled/inner-tunnel"
    "private/etc/rabbd/sites-enabled/control-socket"
         Also, after four years of intense daily use it is cluttered with much junk,  and every app that I was curious about, and I am a very curious guy.
       So I know my limits, (and now my nephew). I dumped my pc for a Strawberry iMac a few years ago, and so far every problem I've encountered, or brought on myself, the Mac has resolved with its own inner elegance - in spite of my novice bungels - and now I honestly feel ashamed, in addition to the need to apologize to a machine for allowing a peasant into the Royal Grounds - so I am calling the Wise Ones in for this one.
       Crazy, I know, but to me a Mac represents something far beyond the ordinary  input ➛ process  ➛ output  title/function customarily assigned to a machine - I sense an odd kind of morality involved, one that I need to respect.
        So, these are my reasons for wanting to do a clean install, correctly.
            Thank you,  Truitt

  • Selling G4 iMac - How do I perform a clean install

    I'm selling my G4 iMac to work and they have given my a Tiger disk to install. I would like it to erase all my old files such as my financial items and my photos as well as my music, etc.
    Is there a way of doing a clean install which takes the computer back to square one with just the basic info on it?
    Thanks!

    Boot from the restore disc. Go to the Apple menu and select Disk Utility. In Disk Utility, reformat the hard drive and choose the option to write all zeroes. After that is complete, use the restore disc to restore the iMac to its factory condition.

  • True you can't clean install Intel iMacs?

    Hi,
    When I get a new Mac I generally zero out the drive and reinstall the OS and apps from the provided install discs and run a clean system without all the extra languages, etc.
    Somewhere on this forum I thought I read that the new Intel iMacs cannot be restored from the install discs after zeroing the HD.
    Is this correct? If so, why not?

    It doesn't matter if you clean install it or not as
    far as bluetooth goes. When you first boot the
    computer after a clean install, it will do a search
    for a bluetooth mouse or keyboard by default.
    glor
    I learned something very disturbing earlier today from Applecare Tech Support. I tried to boot from my install DVD (holding "c" down as instructed) but it hung. Tried three times with same result. When I called Applecare, they said you MUST HAVE A WIRED KEYBOARD AND MOUSE to boot from the install DVD because Bluetooth doesn't activate early enough for the wireless input devices to be seen in order to complete the various commands.
    Their advice - go buy a USB keyboard and mouse so when I have to boot from the install DVD, I can!
    This after I ordered my iMac online and PAID EXTRA for the wireless and, on top of that, was not sent a USB set along with the wireless. I feel a little ripped off...

  • How do you perform a clean installation of Tiger?

    Can someone explain the process of installing a clean copy of Tiger on a Mac that already has Tiger on it (after backing up of course). I know how to do this on windows, but have never formatted and reinstalled the OS on a Mac before. Any help would be appreciated.
    Thanks!

    From Disk Utility, go to Restore Tab. From there you select the source and target and it will do a volume copy. Make sure it boots and works.
    You can use FireWire or 2nd internal drive for your backup.
    Having a bootable backup is one of the most essential things you can do to eliminate and avoid problems.
    There are a couple good books I got my brother, we've both used computers for 40 yrs but he never used a Mac before.

  • Is there a way to perform a clean install without the Internet on the computer that my iPhone is backed up on?

    I don't have Internet on my PC that my iPhone is backed up to. Without connecting it to the Internet, how can I perform a clean install? Since iOS 7 my battery life has been crap, I've tried everything except a clean install, so this is my last resort but I wanna make sure I can do it before I wipe my phone.

    Installing iOS requires an Internet connection, there is no way around this.

  • How to Perform a Clean Install of Panther 10.3

    I am currently running Jaguar 10.2.8 (no OS9) on an iMac G3/400, 320 megs ram, dsl internet. I want to perform a clean install of Panther 10.3 (not the upgrade or archive + install). After placing the first Panther disc in the slot, I get a screen on which I click the install icon, I then click the restart, the machine reboots, gives me an installation screen asking me to choose the language, I choose English, then click "continue", I then get a screen telling me I cannot install OSX because the "firmware" is not up to date. I then have to click on the "close" button, then use a pin to get the cd out of the machine. I thought the only firmware update necessary was when you want to install Jaguar over OS9. How can I fix this situation so I can install Panther? I am not much of a techie, fairly new to Mac so please make your reply easy to follow. Thanks.

    The firmware update for your model is required for running OS X regardless of which version you install. You will need to install OS 9.1 or later in order to install the firmware update if the computer has not been updated.
    OS 9 should have been included with the computer as part of the original software that came with it. You can install OS 9 on the same volume on which OS X is currently installed or you can erase the drive before installing OS 9. After you perform the firmware update you can do an Erase and Install of Panther.
    You should avoid using a pin to forcibly remove a disc from the optical drive. Just restart the computer and hold down the mouse button to have the disc ejected. See the following:
    Five ways to eject a stuck CD or DVD from the optical drive
    Ejecting the stuck disc can usually be done in one of the following ways:
    1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
    2. Press the Eject button on your keyboard.
    3. Click on the Eject button in the menubar.
    4. Press COMMAND-E.
    5. If none of the above work try this:
    Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
    /usr/bin/drutil eject.
    If this fails then try this:
    Boot the computer into single-user mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

    I have a new SSD drive and need to either migrate my old HD data, including the Windows 8.1 OS or do a a clean install.  I have obtained the ISO, prepared the boot for the flashdrive and downloaded the install software.  It asks for the product key.   I used the suggested BIOS reader and obtained "a" product key off the BIOS and used that it but (as above) it does not recognize the image.
    How id I get my single Windows license onto my new SSD HD?  Reload, clean install, ???
    How do I get the proper product key or confirm it is correct? 
    It is a new system with little data that I need to copy. I just want the operating system.  I have the driver disc that came with it.

  • How to perform a clean install of Mountain Lion on MBA without usb?

    I purchased a new MBA last November and I want to perform a clean install of Mountain Lion (for various reasons), however, the MBA didn't come with an install usb drive from Apple.  When I go to the app store it says I need to buy the OS even though it's already on my computer.  After all the searching I've done I can't find the answer on what I need to do.  Do I need to buy Mountain Lion even though it came with my computer?  Please help, thanks!

    If you purchased your MacBook Air in November, it means that your Mac already came with OS X Mountain Lion, so even if the App Store tells you that you haven't purchased it, the truth is that it's registered to your Apple ID and you can redownload it without any problem.
    Hold Command and R keys while your Mac is starting to start up into OS X Recovery and try to reinstall OS X. It will ask you for the Apple ID you used to set up your MacBook Air, so introduce it. If the OS X download starts, close the installer by pressing the red button at the top left corner of the window, because you can reinstall OS X.
    Then, open Disk Utility, choose Macintosh HD in the sidebar, go to Erase tab and erase the drive. Finally, close Disk Utility and reinstall OS X. Make a backup of your data before erasing your disk
