How does one un-install Lion and revert to Snow Leopard?

Anyone know how to un-install Lion and revert to Snow Leopard?

Downgrade Lion to Snow Leopard
1.  Boot from your Snow Leopard 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. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.

  • How do I uninstall OS Lion and revert to Snow Leopard

    Hi all, I need to use Microsoft Office Mac Version in my work. And OS X Lion don't support that. I am desparate to know how do I unistall the OS X Lion, and revert to Snow Leopard so that I can resume working on my MacBook Pro. Please help.....

    MS Office for mac 2004 is indeed incompatible I believe but 2008 onwards isn't. You should consider upgrading your MS Office to be compatible. Apple is not responsible for making 3rd party software compatible with its OS, its the 3rd party developers who updates their softwares and drivers.
    You can certainly revert back to Lion BUT it depends what type of machine do you have?Did you purchase Lion as an upgrade?is your machine Lion preinstalled?

    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

  • How do I add Mountain Lion and still keep Snow Leopard for use on specific software

    I currently am using OS 10.6.8 which supports Final Cut Studio version 7.5. I do not wish to change my Final Cut work, however I am now developing APPS and need the xcode tools which are only supported on OS 10.7 or higher. Can someone please direct me to any information on how I can set up my Macbook Pro to run both OS systems?

    No, you buy & install Mountain Lion on a new partition, leaving the original alone. You will need to reboot from one to the other to use either version of the OS.
    As you can see from this I still have Lion on my internal while I'm running Mountain Lion on an external drive - this may also be an option for you?

  • How does one silence mountain lion startup sound?

    How does one silence mountain lion startup sound?              

    After asking this question many times and always getting the ususal fixes (that don't work in Mountain Lion) Psst, Startninja, turn down the sound when you shut down, yada yada yada. And the "why don't you just put it to sleep" comments :/  duh..  Sometime we want to shut it down!! Even Apple support has no idea how to do it. Here's is the fix and it is so simple it hurts.
    Controlling the volume of the startup chime is easy to set in the System Preferences Sound panel, but you need to make two different settings if you have external speakers connected to your Mac. There is no need to use scripts or any other coding to make this adjustment.
    There are both internal and external speaker output settings in the sound preference pane. In order to adjust (or turn off) the volume of your Mac's internal speakers, nothing must be plugged into the headphone jack. Keep in mind that this setting completely controls the volume of your internal Mac speakers, so if you mute the sound, and have no external speakers, you will get no sound at all from your Mac.
    To adjust the volume on your Mac's internal speakers:
    Unplug speakers or headphones from the headphone jack.
    Go to System Prefs > Sound, then click on the Output tab.
    You will then see Internal Speakers (Type built-in) highlighted in the window.
    Adjust the output volume (which also controls the chime volume) in the slider at the bottom of the window. Remember if you mute it there will be no internal speaker sound.
    To set the volume for your external speakers:
    Plug in speakers or headphones to the headphone jack.
    Go to System Prefs > Sound >, then click on the Output tab.
    You will then see Headphones (Type built-in) highlighted in the window.
    Adjust the output volume (which controls the chime volume in the external speakers) with the slider at the bottom of the window. Remember if you mute it there will be no external speaker sound.

  • How do you transfer from mini to imac with fire wire if iMac has Lion and mini has snow leopard

    My logic board has gone on my mini(intel) and I need to transfer this machine to an iMac(with Lion) how do I do this as it doesn't seem to be working with my disc.My update to Lion was purchased as a download and the only disc I have is snow leopard to reboot.

    If your Mac mini has a dead logic board then you will not be able to boot it at all, not even in Target Disk Mode. You would either have to get the logic board repaired, or remove the hard disk and either put it in a disk enclosure or connect it in some other way to the iMac.
    The fact that the two Macs ran different versions of OS X is irrelevant, once you have the drive connected to the iMac you can run the Migration utility to migrate the user account and data.

  • Is there a way to get rid of Mountain Lion and return to Snow Leopard?

    Eversince apple replaced my hard drive due to a recall and I installed mountain lion because it was touted as the greatest, i have been greatly disappointed. My system has slowed to a crawl, and there's just too much going on. I don't see the benefit and feel ripped off.

    Restore your backup. (The one you made prior to replacing the operating system)

  • In mail in lion and also in snow leopard you were able to click on an incoming email address and select it in spotlight , this feature in mountain lion is now gone , where did it go it was really useful?

  • I wanted to buy a Dragon ,Speech Recognition Programme for Mac but it says its for Lion, and I have Snow Leopard. Would it have worked on Snow leopard?

    I wanted to buy a Dragon ,Speech Recognition Programme for Mac but it says its for OS Lion, and I have OS Snow Leopard. Would it have worked on Snow Leopard?

    The simplest method would be to ask them for their Snow Leopard version and say you can't upgrade to 10.7 or 10.8. I'm almost sure they will sell you a copy.
    Generally if your machine can only upgrade to 10.7 Lion and not directly to 10.8 Mountain Lion, then it's best left on 10.6.8. in my opinion as your going to loose too much other software and slow down your machine in the process.
    This rapid OS X upgrade cycle has caused plenty of problems for users and developers alike, so I suspect you will find a sympathizer with the developer.
    In fact I'm not recommending Mac's to anyone anymore because Apple simply has lost touch with reality.

  • If I skip Lion and upgrade from Snow Leopard, will there be a price difference?

    I know you can upgrade from the most recent Snow Leopard to Mountion Lion. However, I have heard I may get change more if I don't upgrade from Lion first. My question is, is it true?

    No.

  • How does one use the middle and right buttons in AIR without the cursor showing?

    All I want to do is use all three botton clicks without the cursor showing (assistive technology situation). So I use Mouse.hide(). All works fine with the Left mouse button. With the middle and right buttons the cursor reappears as soon as the middle and right mouse is in the DOWN state (and stays visible until rehidden--see code). Are there Mouse parameters that could be added? (I can't find any such references.) Do I need to create a custom cursor Class that makes the cursor invisible at all times? Here is my simple AS 3 test code.
    // MyClickListener.fla
    // Using the Stage to listen for button events
    // Why do the Middle and Right clicks reexpose the mouse cursor as soon as the DOWN state is encountered?
    import flash.display.DisplayObject;
    import flash.events.*;
    import flash.ui.Mouse;
                Mouse.hide();
                var leftClick:int = 0;
                var middleClick:int = 0;
                var rightClick:int = 0;   
    function leftClickHandler(event:MouseEvent):void
                // Mouse.hide();   // I do not need this -- mouse cursor does not reappear
                trace(event.target.name);          
                trace("You pressed the Left Button.");
                leftClick ++;
                trace("Left Clicks = " + leftClick);
    function middleClickHandler(event:MouseEvent):void
                Mouse.hide(); //I use this to rehide the mouse that reappears after click.
                trace(event.target.name);
                trace("You pressed the Middle Button.");
                middleClick ++;
                trace("Middle Clicks = " + middleClick);
    function rightClickHandler(event:MouseEvent):void
                Mouse.hide();  // I use this to rehide the mouse that reappears after click.
                trace(event.target.name);
                trace("You pressed the Right Button.");
                rightClick ++;
                trace("Right Clicks = " + rightClick);
    stage.addEventListener(MouseEvent.CLICK, leftClickHandler);
    stage.addEventListener(MouseEvent.MIDDLE_CLICK, middleClickHandler);
    stage.addEventListener(MouseEvent.RIGHT_CLICK, rightClickHandler);
    Help appreciated.
    Thanks,

    Dear Tuttle and Tom:
    You both sent me to the appropriate place. I downloaded the instruction file (PDF). Many thanks.
    Incidentally, I then downloaded the upgrade offered at the top of that page (from v3.2 to v3.2.4) but after ±90% of the necessary time needed, it shut down with a "Failed to Mount" message (whatever that might mean). It took more than 28 minutes to download that much even though I'm using DSL! Have either of you upgraded to v3.2.4 with or without difficulty?
    Thanks again for your right-on assistance.
