HT3910 How do I erase Mountain Lion and reinstall Snow Leopard?

Can anyone help me erase Mountain Lion and reinstall Snow Leopard. When I had installed Mountain Lion,I discovered that my music notation program, Overture was not working with Mountain Lion. Please help me, years of work is for now lost.

Back up your data files.
Use the Snow Leopard installer disc to completely erase your hard drive and everything on it.
Re-install the SL operating system, then all your applications, then your data files.
If you happened to make a bootable backup clone of your hard drive before installing Mountail Lion then you can just clone the backup back to your drive.

  • How do I uninstall mountain lion and reinstall snow leopard

    If I had known that I would not be able to use my excel files I would not have purchased OSX Mountain Lion.  Is there a way to uninstall mountain lion and reinstall snow leopard?
    Thank you,

    To get more to the point the answer is the only way to go back to SnowLeopard is if you have a complete backup of your system from before the upgrade.
    If you do you would boot off your original SL DVD wipe the disk and install SL and then restore from your SL backups.
    Short of that here is no way to go back. But as the others have offered there are other less drastic means to deal with the problem.

  • How do you erase mountain lion to install snow leopard?

    Hi, My mother now has a new to her late 09 mini that originally shipped with snow leopard. When she bought it it came with mountain lion preinstalled from a private seller. We were thinking that to be on the safe side that it might be better to erase and install what's on it just to be sure it is secure. I tried to erase and install snow leopard from a disk but it says that the installer is not compatible with this version of osx(mountain lion). Question: How do I erase mountain lion and install snow leopard?
    I've read here that there is possibly a built in recovery disk that I can use to erase and reinstall mountain lion. Q: Is there a built in recovery disk available in my situation? and if so should I use it or be even safer by installing snow leopard instead?
    Thank you,

    I think I found the answer (from sl install disk use disk utility to erase then install sl). Thanks for looking.

  • How do you erase Lion and reinstall Snow Leopard

    I want to remove Lion and reinstall Snow Leopard.  I put the install disc in and clicked Install so that I could get to the disc utilities.  Got a reading that this version of OS X cannot be used on this computer.  I'm using a mid-2010 15" MacBook Pro.  I don't have any backups made, but I am not worried about that...I just want to go back to using Snow Leopard.  Lion has too many quirks I don't want to put up with.  Any suggestions?

    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 (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
    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.

  • HELP! How do I remove Lion and reinstall Snow Leopard and my files

    HELP! How do I remove Lion and reinstall Snow Leopard & my files  BUT I just discovered my Apple Time Capsule which was using Time Machine DIED
    I had to go to MacMall and have the Time Capsule data transfered to a new BAK drive($300+$300)
    (The Apple Store sent me there as they said they do not do data transfer)
    Now what do I do?
    ? ?  One Senior advisor said that I will have to drag and drop the data file or files? from the Time Capsule BAK drive back to my iMAC but will that include all           the Snow Leopard operating system ?
    ? ?  Another senior advisor said I will have to wipe my hard drive then install Snow Leopard then "drag and drop",  ?  ??
    All my business leases, database, spreadsheets. letters, mail merge files, and so on are not available with Lion -
    I AM VERY ANGRY AS I NEVER SAW THAT WRITTEN ANYWHERE !!!
    I am seriously confused and I AM SCARED TO MAKE A MISTAKE-HELP !!
    WHAT DO I DO ?  AND   IN WHAT ORDER? PLEASE HELP!

    Your post is confusing to read too.
    It sounds like you still have your files on your Mac. Why do you want to back track to Snow Leopard on your Mac? Why can't you read your files from your Mac? If your files are on your Mac, why are you taking them off your broken Time Capsule? You don't have to install Snow Leopard to transfer your files back to your Mac. Maybe step back a bit and explain your situation a little better with details.  For instance, what's a BAK drive? Suggest you explain what you are trying to do?
    Before you do anything, create a backup of your Mac to another disk drive.. suggest you use Carbon Copy Cloner to make another copy of your Mac.

  • Need to reformat HDD running Mountain Lion and install Snow Leopard

    I bought a new Retina Display MBP and want to sell my Late 2008 MBP.
    My 2008 MBP is running Mountain Lion, but I want to format the HDD and install Snow Leopard. When I try installing Snow Leopard from the DVD, I get the following message: "You can;t use this version of the application Install Mac OS X.app with this version of Mac OS X."
    How can I get this done?

    The only way to do it is to boot from the Snow Leopard installer disc and the erase and install.  In other words you cannot "downgrade" OS X 10.6 over top of 10.8.  Besides, if selling it an erase and install is the best thing to do anywya - gets all your info off it.

  • How to downgrade from Mountain Lion back to snow leopard with Time Machine

    The final straw was the horrible mouse sideways page wiggle while trying to scroll down and read safari pages. Even after turning the feature off, tech support said it will still wiggle a little. That and the HORRIBLE grey icons everywhere was enough to send me back to my beloved iMac I loved when I bought it. I'll give up the iMessage and the few new items ML gave me. But as many others said, what I got new was far less than what was taken away. 
    So what tech support had me do was this. Even though the apple engineers said it would not work, apple tech support had me try it and it worked for me so good luck. Engineers said that after you install mountain Lion, it messes with ALL your time machine back ups and won't revert back to snow leopard even if you select a snow leopard date back in time.  That didn't happen to me.  I have a 2010 27 inch iMac
    This worked for me but PROCEED AT YOU OWN RISK
    Export individually any email folders or photos or data you will lose between now and the date you are reverting back to.
    1. Insert Snow Leopard DVD that came with computer. The install disk not the applications. Make sure time machine external drive IS connected.
    2. Restart computer and when you hear The Mac chime, hold down the C key and then it will take several minutes to boot up from the DVD.
    3. Select the little blue triangle to continue in English.
    4. When it gets to the screen that says "continue" stop. There might be a screen or two before this one I can't remember but either way stop at the word continue.
    5. Go up to the top left and find the UTILITIES pull down menu and select disk utility.
    6. In the window that opens up, Select the Apple drive which should be the very top one in the window.
    7. Select erase.. it should be Mac OS extended journaled
    8 select erase and maybe a password. It only takes a few seconds
    9 go back up to UTILITIES in upper left and then select restore from time machine or backup or whatever it says. It's the last choice.
    10. Select the external time machine drive and navigate to the date you last had Snow Leopard running and that will be the date it restores to. You will lose any data between now and then but you can export your mail, export photos, and other items separately. I only stayed on ML For a few days before hating it enough to go back so I had no loss of data except a few emails.
    11. Hit RESTORE. And then it will take several hours. When you restart it, it should come right back to that day you selected as if ML  was just a bad thought on someone's drawing board.   If for some reason it still comes up ML, Then they said to erase HD Again (steps 1-8) and then manually drags back USER folder or individual folders with Mail, photos etc.   if this way doesn't work, have another plan printed out so that you are not stuck by this one.
    Good luck. Proceed at your own risk..

    The ultimate solution:
    You need an USB of at least 5 GB and the Snow Leopard Install DVD.
    1. make a bootable USB with Disk Utility in it:
         a. download the Mountain Lion Installer from the App Store
         b. quit the installer after download
         c. find the installer in the Applications folder
         d. option+click in it and select "Show Pakage Contents"
         e. go to Contents>SharedSupport to find there the InstallESD.dmg file and mount it by double-clicking it
         f. with the Disk Utility, restore its contents into your USB
    2. boot from the USB:
         a. restart the computer and hold-down the option key while booting
         b. select the USB and boot
    3. run the Disk Utility and format in ONE partition the HD of your computer
    REMEMBER: BACKUP YOUR HARD DISK BEFORE DOING ALL THESE, YOUR DISK WILL BE EREASED AND DATA BECOME UNRECOVERABLE OTHERWISE
    4. insert the Snow Leopard DVD and reboot from it
    5. follow the on-screen instructions to install OS X 10.6
    After this, you can, if you will, upgrade to Lion or stay in Snow... Good Luck!!

  • How do I install Mountain Lion - I have snow leopard ?

    I am completely confused
    I have Snow Leopard - Mac OS X 10.6.8  on my Macbook 7,1
    I have XCode 3.2.3
    Want to upgrade to Mountain Lion 10.8
    Downloaded a huge dmg - about 1.7 GB from iOS Dev center ( am a registered user here after I paid USD 99 )
    Clicked on ' Technical Resources and Tools ' >> Clicked on 'Downloads' under ' Resources for iOS6 ' >> See a XCode 4.6.1 option to download
    It also says :
    Posted Date: March 14, 2013
    Build: 4H512
    Included iOS SDK: iOS 6.1
    Included Mac SDK: Mac OS X 10.8
    Finally got the download complete ( have very poor network connectivity at home )
    double clicked it and it opened a window where I dragged and dropped it
    something happened and in 'Applications' XCode is shown but with a prohibitionary image on the icon
    If I double click it - it says :
    "You cant use this version of the application Xcode with this version of Mac OS X - You have Mac OS X 10.6.8 The application requires Mac OS X 10.7.4 or later "
    which is fine - I downloaded this dmg because it said it had Mountain Lion
    The way I thought this would work is the installer would upgrade to Mountain Lion and then XCode - but I dont see anything apart from XCode
    Please help
    satish

    Firstly, you cannot get Mountain Lion as a developer for iOS. You have to become a registered OS X developer. Secondly, if you want Mountain Lion then open App Store, sign in with your Apple ID, purchase and download Mountain Lion.
    XCode is not Mountain Lion and Mountain Lion was never included with XCode.

  • Upgrading to Mountain Lion of reinstalling Snow Leopard?

    Hi,
    I want to reinstall my OSX, so I was wandering if it was a better idea to buy Mountain Lion instead of installing Snow Leopard again.
    I have a 2010 MacBook Pro (dual core 2.66 GHz i7, 4GB RAM, etc.) but I am worried that Mountain Lion will be significantly slower than Snow Leopard. This is my first Mac so I am judging this by my experiences with Windows, where XP was much faster than Windows 7.
    I currently don't need any of the new features that were added to Lion or Mountain Lion and I am fine with Snow Leopard (I know some guys that are still using Tiger). Still, I would not like to fall far behind since the newest OSX is already two versions infront of mine, but what is mostly concerning me is the speed of my Mac. Has anyone tried it on a MacBook Pro like this one? What do you think will be the best option? (I don't care about the money since Mountain Lion is only $20)
    Thank you,
    Vince.

    I'm using Yosemite on an early 2008 iMac, so Yosemite should run on your computer. The biggest thing that would help Yosemite run better is maxing out your RAM.
    I would pick Mountain Lion over Lion. Tried them both and Mountain Lion was much better.
    One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won’t have to go though the revert process.
    Check to make sure your applications are compatible.

  • How do I erase mountain lion and restore lion on an iMac 27 thats new

    Due to compatiability issues with security system I need to go back to 10.7.4 that came with computer. After update to 10.8 I have a lot of hardware that is 10.8 compatible that no longer works. IP cameras , alarm system ect.

    If this is on a 2011 model o[r mid 2012 that came with Lion originally boot to the Internet Recovery system. That is booting the computer over the internet.
    Hold down the Command+Option+r keys until you see a spinning globe in the center of the screen. Once the Recovery system fully loads use Disk Utility to Re-Partition the drive as one partition. you must do that to completely remove Mt Lion and the Mt Lion Recovery HD partition.
    Once that is done exit DU and select Reinstall Mac OS X. Lion will be downloaded and then the install will reboot the system and start the install of Lion.

  • How do I install mountain lion but keep snow leopard as a bootable os

    I'm caught in a vicious circle.
    I need mountain Lion to be able to use iCloud and to be compatible with a couple of apps on my iPad. However some of my major apps on my mac Pro won't work under Lion or mountain lion.
    SO the answer is to have both Snow Leopard and Mountain Lion on my Mac Pro.
    Does anyone know of any instructions on installing Mountain Lion onto one SSD, whilst leaving Snow Leopard on another, allowing me to boot from either.
    Also - any advice on the cleanest way of installing my apps under Mountain Lion (those that are compatible). I'm confused to how I can install my apps twice, especially if I have all ready registered Unser Snow Leopard.
    Thanks

    I'm assuming that you currently have an SSD with Snow Leopard on it, and another SSD with no operating system. Is that correct?
    What I would do is use the Snow Leopard DVDs to install a fresh copy of Snow Leopard on the SSD that currently has no operating system, and "migrate" your data and applications from the other SSD. (alternatively, you could use something like Carbon Copy Cloner to duplicate one SSD onto the other - but that's probably only an option if one SSD is completely blank or you're willing to erase it).
    Then upgrade to Mountain Lion on the original SSD.
    When you're done, hold down the option key when you start up to select which OS to use.
    For many applications, it won't matter which SSD they're on - you'll be able to run them from either system without worrying about where the app is installed (each will have it's own preferences, stored on the current startup drive). But some applications are more complex, and rely on additional files that are scattered around the Library folders on the startup drive. Since you migrated your applications and data, you should have everything that's needed on both systems, including license keys, etc. I did this for a little while with Quicken, and I actually left the Quicken app on the Lion drive - it worked just fine even though I started up from an external Snow Leopard drive (I skipped the migration step entirely, and reentered my Quicken license code when starting up from Snow Leopard).
    How successful this will be depends on exactly which applications you're using. Most of them will be OK, but if you're using something that has some esoteric copy-protection mechanism, you might run into a little bit of trouble. Consider upgrading the "new" Snow Leopard install to Mountain Lion, if that's the case, so you're original system SSD will remain Snow Leopard, with no changes.

  • Can I upgrade to mountain lion and skip snow leopard from my OS X 10.6.8?

    Hi guys, Im not sure on this thus any one can advice me on this?
    I'v missed the snow leopard upgrade and now came the mountain lion; can I just upgrade and down the m.lion directly? Or do I need the snow leopard in order to install the mountain lion?

    Mac OS X 10.6.8 is Snow Leopard and can be upgraded directly to Mountain Lion 10.8 without going through Lion 10.7.

  • Anyone know how to uninstall Lion and reinstall snow leopard without having to pay the $29?

    Ever since I purchased and downloaded Lion I have been having problems (applications not running properly or not at all and the computer locks up like every 10 minutes resulting in me having to restart) and want to go back to snow leopard until I feel comfortable that Lion is ready to go.

    Thanks Roscoe . . . .
    I came back to this forum to share my experience. I'm working with a 2007/08 - 17" MB Pro. With the LEOPARD OS, not Snow Leopard. I used my original discs and reformatted, reinstalled Leopard. I was able to open Time Machine and restore the files saved on on an external drive. I used this time to make changes to my Apps, and having just doubled my RAM prior to the 'Lion Upgrade', had no issues of slowing or freezing as others are apparently having. Like you, this was relatively painless, though it did take some time to transfer all of my files.
    I hesitated performing this process for nearly a month, but kept checking my back-ups to ensure that I had still some saved from the Leopard days. Unfortunately, I was unable to do much of anything. I'm a graphic designer and sell items online, EVERYTHING came to a complete stop with Lion. I couldn't communicate with my printer at all, no fax, no copies, no prints, no scans. I couldn't download images from my camera. Some of my Apps, stopped working, I hated the missing 'Save As' feature. My image viewer and browsers crashed constantly, and my home network 'LOST' me! I couldn't take another day of NO productivity!
    My advice to anyone changing or upgrading ANY O.S., whether Mac or PC, always; ALWAYS back up your drive first! We should be backing up often anyway, but it is certainly important to ensure the security of all of your files and program downloads or installations by copying everything prior to making any hardware or software changes. For a small investment of $50 to $100, you can get an external drive. Having the capability of restoring all of your data is  . . . priceless!
    Thanks everyone for sharing. Good luck to those experiences these problems. Have Faith, Apple will fix it's issues, and the other manufacturers WILL catch up on the driver codes. We all just need to be patient, until then;  keep on 'backing up'!
    *** JJ; were you able to restore an earlier back up? Did that fix your issue? I found a great deal on RAM from Crucial, sometimes this will help increase our speed and performance . . . . just a thought.

  • Can't erase hard drive and reinstall Snow Leopard (SuperDrive)..

    Running OS X 10.6.8
    2.13 GHz Intel 2
    2 GB 1067 MHz DDR3
    I have the original "gray discs" with Snow Leopard on them, and a SuperDrive. I would like to completely wipe the computer, and start over with just Snow Leopard. When I tried to do this yesterday following this tutorial, the whole process sort of froze at Part One, Step Three.
    For the lazy non-link-clickers, here's the instructions I followed:
    1. Turn on the computer.
    2. Insert the Mac OS X Install DVD into the optical drive.
    3. Press and hold the "C" key while the computer starts up. The computer will start up using the Install media.
    ....And that's as far as I got. The machine turned on, the DVD whirled and clicked, and the screen glowed gray for about 10 seconds. Then, it went black, and the DVD stopped whirring. Then that cycle repeated. Over and over and over and over. For over 24 hours.
    So, what is going on, here?

    Well, Kappy, you were right: my 2009 MBA came with Leopard, so those Snow Leopard gray discs I was using did not come with my machine.
    Unfortunately, I was unable to find the Leopard gray discs that must have come with the computer.
    So, I found a retail copy. And then I:
    1) Inserted the retail OS X 10.5 disc into the SuperDrive.
    2) Double-clicked "Install Mac OS X.app" in the DVD contents pop-up
    3) Clicked "Restart" when prompted by the installer.
    ....And that's as far as I got. Again, the machine turned off and then back on, the DVD whirled and clicked, and the screen glowed gray for about 10 seconds. Then, it went black again, and the DVD stopped whirring. Then that cycle repeated. Over and over and over and over... Again.
    Sigh. What is the deal.
