How to downgrade from Mac OS X Leopard to Tiger

I have Mac OS X 10.4.0 CDs (Retail Discs), but when I try to install it says that "Mac OS X cannot be installed on this machine", even though I meet all the requirements. I suppose that this is because versions prior to 10.4.4 do not support Intel processors. What can I do?

If it originally came with 10.4.10 then you can install 10.4.10 on it but you will need a set of discs that are identical to the ones originally supplied with the computer. A retail set (such as on CD) will not install the correct (Intel) version of the OS and will simply refuse to install. No retail sets (except Server) were sold with Intel installers. If you no longer have those discs you should call Apple Customer Support 1-800-767-2775. Provide the serial number and specifications of the Mac. They may be able to provide a replacement set of discs for a reduced fee.

  • How to downgrad from mac OS 10.9 to 10.8?

    Hi All,
    I have macbook pro 15 Early 2011. I have updated my macbook pro with Mac OS 10.9(Mavericks). After fewdays my macbook become terribly slow. So i decied to downgrade from MAC OS 10.9(Mavericks) to MAC OS 10.8(Mountain Lion).

    Regards

    Bhasin,
    to downgrade from Mavericks to Mountain Lion, you’ll need to boot into Recovery mode, run Disk Utility there, and completely erase your internal disk. Since you have an Early 2011 model, it  originally came either with Snow Leopard (and two grey installation DVDs in the box) or Lion (and no installation DVDs in the box) installed. If it originally came with Snow Leopard, you’ll need to reïnstall Snow Leopard from its grey Mac OS X Install DVD. If it originally came with Lion, you’ll need to perform an OS X Internet Recovery to redownload Lion from Apple’s servers and reïnstall it. Once either Snow Leopard or Lion is installed, run Software Update; once the OS has been updated, you can then upgrade to Mountain Lion.

  • How can I downgrade from Lion to Snow Leopard?

    Hello.
    Yesterday, I upgraded my Mac to Mac OS X (10.7 Lion) from 10.6.8 Snow Leopard. However, I wish to downgrade.
    Obviously, I would like to not lose any data at all. However, I have never downgraded before.
    I still have the Snow Leopard installation disk that came with my Mac.
    How should I do this? I was thinking it would be easiest to simply head on over to an Apple Store...
    I did some research (aka Googling), and I read up on the subject quite a bit.
    If I simply put in the disk, will I be able to downgrade from Lion to Snow Leopard as easily as the upgrade was?
    Also, I have heard about holding down the "C" button to do this... how exactly?
    I have never backed up my Mac, nor used Time Machine.
    Also, is it possible to install Snow Leopard on a separate disk, and set it up so that I can switch between them on command?
    Will all of my preferences be saved, or does this wipe everything, not just the system and libraries folders?
    I realize that I have a lot of questions, and therefore I appreciate everyone's help in advance. Thanks again.
    Sincerely, Zach

    Backup your files.
    Booting From An OS X Installer Disc
    1. Insert Snow Leopard Installer Disc into the optical drive.
    2. Restart the computer.
    3. Immediately after the chime press and hold down the "C" key.
    4. Release the key when the spinning gear below the dark gray Apple logo appears.
    5. Wait for installer to finish loading.
    Erase Drive
    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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Upon completion quit DU and return to installer. Install Snow Leopard. Restore your files after the installation has completed.

  • How do I downgrade from Mac OS X Lion 10.7.5 for my wife , me and my office

    how do I downgrade from Mac OS X Lion 10.7.5 for my wife , me and my office

    You cannot downgrade a machine that shipped with 10.7 installed. Such a machine can only run 10.7 or later. As for the older machines, you would need to use the old Mac OS X install disks to erase the hard drive and reinstall the system.
    I don't really understand the issue regarding minimizing windows. If the difficulty is that you want to use the green "+" button in the iTunes window's title bar to resize the window rather than toggling between the full window and the simplified window with only play controls, that is not unique to Lion. That has behaved the same way for some time. Try option-clicking on the "+" button.

  • How do I downgrade from Lion to Snow Leopard without losing iWork 09?  I upgraded my MBP from 10.5 (originally 10.4) to 10.6, then again to 10.7.  Should I go back to 10.4, 10.5 or just to 10.6?

    Thanks for the information!  My sister gave me the MBP for my daughter with Leopard installed.  I purchased Snow Leopard and installed it, then my daughter purchased Lion.  So I do have all the installers.  If iWork wasn't included with any of those, I guess my sister purchased it while running Leopard.  I'll have to contact her.  Thanks again.

  • Downgrading from Mac OS X 10.9 to Mac OS X 10.8 originally shipped

    Hello
    I purchased thiis MacBook Pro 13.3 inches online from Amazone Last June.
    It was shipped with Mac OS X 10.8.
    Being prompted, during 28 October 2013 I wanted to download online Mavericks but failed by corrupting my external drive containing all my backups through the time machine.
    Then, on 30 October, a local Apple authorized service provider also failed to restore my data but however restored the system and installed Mavericks Developer Recovery Update after installing Mountain Lion.
    Now, I want to go back i.e. downgrad from Mac OS X Mavericks to Mac OS X Mountain Lion 10.8 which was originally shipped to me. I do not know if the builtin Mac OS X is still there in the system.
    I shall appreciate if anyone comes forward and help me out.
    Thanks.

    Try booting using Internet Recovery mode
    http://support.apple.com/kb/ht4718
    Backup all your data
    Make sure your network has WPA security. This does not work with WEP networks
    Shutdown your machine
    Press the power button and hold Command-Option-R
    Wait for Internet Recovery to load a list of networks (read the note at the bottom)
    Select your own network
    Internet will now download the Mountain Lion recovery image(assuming your mac shipped with it)
    Select Disk Utilities
    Select your Mac disk
    Warning! This is your last chance to back out!!!!
    Select the Erase tab
    Select Mac OS Extended Journaled and give a name
    Exit out
    Select Reinstall Mac OS Mountain Lion
    Follow the instructions
    Viola! You have downgraded to Mountain Lion!
    Notes
    Sometimes, if the mac already is connected, it will skip the network selection screen
    You must erase the disk in order to let the installer continue
    Good luck! Tell me how it went

    As Niel relaters...
    Leopard requirements/10.5.x...
        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
    minimum system requirements

        * DVD drive for installation
        * 9GB of available disk space (I say 30GB at least)
    Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...
    http://www.ebay.com/sch/i.html?_nkw=mac+os+x+leopard+retail+10.5
    Snow Leopard/10.6.x Requirements...
    General requirements
       * Mac computer with an Intel processor
        * 1GB of memory (I say 4GB at least)
        * 5GB of available disk space (I say 30GB at least)
        * DVD drive for installation
        * Some features require a compatible Internet service provider; fees may apply.
        * Some features require Apple’s MobileMe service; fees and terms apply.
    Which apps work with Mac OS X 10.6?...
    http://snowleopard.wikidot.com/
    It looks like they might still have it...
    http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA
    It's reported that if you have a MobileMe account that Apple will send you SL/10.6 for free.
    If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.

    How to downgrade from iOS 8.3 back to iOS 8.2?

    A handful of people scream about every update that is ever put out. It is the nature of technology and blame. Perhaps try addressing your issue instead of blaming yet another update. you would never had of installed 8.2 if you took these forums as any true representation of iOS users.

  • How to downgrade from iOS 8.1.1 to ios 7.1.2

    How to downgrade from iOS 8.1.1 to ios 7.1.2

    I think the best iOS version for iPad mini 1st gen was 7.1.2.
    I use my iPad with music production software and still it was on 7.1.2 I got no problems, but now I'm in trouble using AudioBus for memory problems when I record to a DAW. Synth softwares are laggy, many crack here and there, like it has no more power to reproduce all the voices I need.
    Really the only way is the jailbreak? 8.1.1 is not optimized for older devices: the update had to be not released through iTunes.
    Bye.

  • How to downgrade from iOS 8.1 to 7.1.2 for iPhone 5 ?

    Dear Experts
    How to downgrade from iOS 8.1 to 7.1.2 for iPhone 5 ?
    The situation is that in Hong Kong, I bought the iPhone 5 for my mainland China friend.
    The seller said that the iPhone 5 was brand new and was come from USA.
    I found that iPhone 5 was in iOS 8.1. I wonder that why brand new iPhone 5 would be installed in iOS8.1?
    My friend finds that the response of iPhone 5 is so late.
    He prefers to downgrade to iOS 7.1.2.
    Please reply.
    Thank you

    You don't. There is no supported way to downgrade iOS. Attempting to do so will void any warranty, forfeit all rights to support, and could very well brick the phone.
