How can I revert back to Snow Leopard (10.6)?

Hello,
I've had it. I can't take Lion any more!! I am one of the idiots who downloaded Lion the first hour it became available. Since then, my life has become a nightmare. Lion is so buggy---Apple blew it big time with this software. Multiple crashes every day, I've lost thousands of saved emails, my calendar is all messed up....I am at my wit's end and I want NOTHING to do with Lion any more.
I don't care how difficult it is---I'm willing to do it. But I don't even know where to turn to get started for such a task, but how can I revert my Operating System back to 10.6.8 (Snow Leopard)? I've been a Mac user since 1985 and I have never EVER had these types of problems. I thought that Apple would have released a software "patch" or something by now---but nope---the drama continues.
I am using a MacBook Pro, my OS is 10.7.1. Please---can someone point me in the right direction so that I can begin the process of dumping this terrible software so that I can go back to something that works?
Thank you very much.

Well, if you made a bootable clone with SL before installing Lion, it's easy - if you didn't, it's a bit more difficult. It will involve having to erase your hard drive, so back up your stuff first. Then, if you have the clone, simply boot from it, erase your drive and clone back. If not, insert your SL install disk, boot from it, erase your drive and reinstall.

  • OSX Lion, It is slow and really lumpy/jerky Can I revert back to Snow leopard?

    Where are Apple?
    Had OSXLion for a week and it is nothing like as fast as the last OS, screen changes are really slow and jerky and the whole thing feels slower. Is there anything that I can do, or can I revert back to Snow Leopard?
    This is a real shame never had this type of issue with Apple before.

    This is a user to user forum.  You can only revert to Snow Leopard through your backup.  You might attempt piecemeal data recovery after backing up your Lion system, and copying your e-mail folders to IMAP if they weren't stored there before.  Spotlight frequently needs to finish updating in the menu in the upper right (it will only have a search field if it is done, and say it is indexing if it is not), or some plugins may need upgrading to be Lion compatible before you upgrade to Lion.  See my FAQs*:

  • Can I revert back to Snow Leopard from Mountain Lyon ?

    Since updateing to Snow leopard my computer has become very slow.  The nice man at the White Cathedral said it was because of the age of my computer (bought 2007) and he wouldn't advice me to update to this level.  I now wish to revert back to Snow Leopard.  Is it Possible and how do you do it.  I have a complete Time Machine backup on an external drive.
    My computer is an iMac, 2.4 GHz Intel Core 2 Duo with 4GB SDRAM.

    Thanks to everyone for their help.  It would appear that I want be able to access my documents from the Mountain Lion Time Machine backup disk after I have reverted to Snow Leopard.  I guess I'm just stuck with a very slow machine.

  • How can I go back to snow leopard my epson stylus Photo TX810FW does not work with Lion

    My Epson Stylus Photo TX810FW printer does not work with Lion how do I go back to Snow Leopard?

    Did you try removing the printer from the queue and then reinstalling it?
    I attempted to print this morning for the first time after upgrading to Lion and discovered that while everything appeared normal on my Epson printer, it would never print.
    I opened System Preference > Print & Scan and deleted the printer.
    I then added the printer back and it now working again. Worth a shoot first I should think.
    Much easier the a downgrade.

  • How do I revert back to Snow Leopard from OS Lion without losing files etc

    I need to revert back as my work VPN cannot operate with the java cocoa version that is part of safari due to the OS Lion upgrade I performed.  I have done a ton of work on my system in the last week and don't want to lose any of it - and no I didn't use time machine.  HOw much am I going to lose when I uninstall Lion and then reinstall Leopard?
    Thank so much for your help,
    cmw

    First, do a full backup of your current system.
    Reformat your hard drive's main partition that you want to revert to Snow Leopard from Lion. This will delete EVERYTHING on the partition, which is why you need to do the backup first.
    Reinstall Snow Leopard from the installer media you own.
    Download then install the Mac OS X 10.6.8 Combo Updater.
    Run Software Update repeatedly until there are no updates left to install.
    Reinstall all your third-party applications.
    Connect the backup you made of the Lion system and copy over your data. You should only have to copy over the files you know about within your own user account folder.
    If you do this right, you'll have everything back in Snow Leopard with no loss. If you do it wrong, well, that's another reason we made a backup all the way back in the beginning of this process - you can always start over.

  • Can I revert back to Snow Leopard after upgrading to Lion?

    I would like to install Lion over my current Snow Leopard 10.6.8 installation but I have some concerns that I may not like it.  If for some reason, I want to revert back to SL, can I use a Time Machine backup to return to my former OS?

    Yes.  Just boot up from your Snow Leopard DVD, and restore the last Time Machine backup that was made before you installed Lion.

  • Can I revert back to Snow Leopard from Lion?

    Hey guys,
    Last night i upgraded to Lion.  Have since found out my Focusrite 24 DSP audio interface wont work with Lion (No Drivers yet).... can i simply re-install Leopard from the install discs that came with my imac until such time as drivers become available for my hardware, then re-install Lion? Can this be done without clearing my entire hard-drive and starting again?
    Cheers

    Just boot from the Lion Recovery partition (option key at startup) and choose to restore from Time Machine backup. (You'll be able to see your last dated and identified SL backup, even if you'd already been using TM with Lion.) It will erase the drive for you and restore a bootable SL. No DVD required.
    Works great.
    (If you don't have a complete TM backup, then you'll have to wipe the drive, install SL and updates, then use Migration Assistant to bring over your partial TM backup, ie: does not include system and apps.)
    Thanks very much for this. I've just restored Snow Leopard from Time Machine, and it only took 30 mins. Worked perfectly. Now I have an OS that works properly (hooray!).

  • How can I go back to Snow Leopard from lion without loosing files, etc.?

    I recently downloaded Mac OS X Lion, but I can't stand it. I've heard you can't get a refund from the app store but I'm not sure how that works and I'd realy like my money back. Also, if I do downgrade, I'm not sure how to back up my files. I have music, documents, and pictures I don't want to lose. I don't have time machine. I have a usb but I'm not sure if it is capable of holding music from itunes? Other than that I'm not sure how else to back up things. I realize I have a lot of questions and I'm not exactly well informed with this stuff so any help would be greatly appreciated (:

  • Can I revert back to Snow Leopard?

    Lion has been giving me nothing but problems.  I am getting Mail error notifications every 5 minutes because of permissions issues, I STILL can't open anything in preview, iCal is not syncing up, and I can't get a connection in iTunes to properly sync to my phone. 
    As far as the permissions issues, I've been told to do the containers folder thing.. but there is no containers folder. 
    Any other fixes from anyone else?

    Of course it is going to be slow. 2GB of RAM is the absolute minimum to install Yosemite. If you are going to do anything on the Mac we recommend that you install as a workable minimum 4GB.

  • How do I uninstall Snow Leopard Server, so that I can revert back to Snow Leopard?

    I was experimenting with the Snow Leopard Server DVD on my MacBook Pro running Snow Leopard.  I started the installation process, expecting that it would not install on the Startup Disk, as I had not booted from the DVD. 
    To my surprise it installed!
    How do I "uninstall" or revert back to Snow Leopard, without have to take such drastic steps that I would lose all of my Snow Leopard System folder contents (such as doing a wipe and starting over with a fresh Snow Leopard install)? Thank you.

    I assume by "back up your data" you mean a Time Machine backup?
    Preferably, yes.
    I have a BootCamp partition to run Windows; does Time Machine back that up, too?
    No, but it won't be affected unless something goes wrong. You still need to back it up, of course, just like all other data.

  • How to revert back to Snow Leopard from Lion?

    Foolishly I just jumped straight in, downloaded Lion and installed it, and well... I really don't like it.  It's not a patch on SL.
    So I'm trying to work out the best way of reverting back to Snow Leopard.
    I have:
    My Snow Leopard install disc.
    A SuperDuper, bootable backup from 48 hours pre-upgrade.
    A Time Machine backup from 48 hours pre-upgrade.
    I'm fairly sure that just putting the SL install disc in, isn't going to work.
    I think I have a couple of options.
    1. Erase the hard drive completely, and then do a fresh SL install, then restore the last TM backup.
    2. Boot from the SuperDuper backup, then restore the last TM backup.
    I'd prefer option 1, as this gives me a clean install (I hope).
    Before I go ahead, can anyone:
    a) See any problems with carrying this out, or
    b) Suggest a better, safer method?
    I'm a bit concerned that SL was an upgrade to an existing OS, rather than a complete OS in itself, so I'm very wary of what might happen if I wipe the drive then put the disc in, hoping it'll give me a nice new version of SL.  Might need to go and do a bit more reading up.
    Thanks.

    For ref.
    Dragged and dropped copies of important files (Docs, Pictures, Downloads, Movies etc) to a spare drive.
    Printed off any docs that I absolutely could not afford to lose.
    Shut down Mac.
    Attached USB drive with SuperDuper backup, and powered up drive.
    Powered up Mac, and immediately pressed the option key.
    From the window that popped up, chose my USB drive as the boot disk and pressed return.
    Mac powered up running Snow Leopard from USB drive.
    Started Disk Utility, and erased the disk labelled 250.06 GB Fujitsu.... etc  In the 'name' field, entered 'Macintosh HD'
    Started up SuperDuper! and copied my backup over Macintosh HD.
    Incidentally, the first step it took was to erase Macintosh HD anyway, so I could probably have skipped the first erase.
    Let SuperDuper! do it's thing for 90 mins.
    Once it had completed, closed the machine down (it wouldn't let me eject the USB drive, as presumably it was still using that as the boot disc).
    Detached and powered off USB drive.
    Pressed Mac power button and crossed fingers...
    And goodbye annoying Lion, hello again, good old Snow Leopard!
    Didn't even need to restore the last Time Machine backup.
    I may take another look at Lion again, further down the road, when hopefully Apple will have realised that OS X and iOS are two completely different animals, and that we don't all want our Macs behaving like our iPads.
    For now though, I'm sticking with SL.

  • I  have been having nothing but trouble with OS 10.6.8.  Many of my appliatins will not work..  HOw can I revert back to a previous version of OS x?

    I  have been having nothing but trouble with OS 10.6.8.  Many of my applications will not work..  HOw can I revert back to a previous version of OS x?

    Before you revert anything try this:
    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Next time don't post something like "nothing but trouble." Tell us exactly what the trouble is and provide any additional information such as error messages.

  • How do you switch back to snow leopard, lion is crap?

    How do tou switch back to snow leopard? Lion is crap, so dissapointed.

    Keep the inflamatory comments down or the thread will disappear, as long as your questions are supported related it's fine.
    Here's how to go back to Snow.
    How can I uninstall OS X Lion and go back to Snow Leopard?
    1: Copy your user file folders (Documents, Pictures, Movies, Music, not Library) to a external blank Disk Utility formatted HFS drive (not TimeMachine) and disconnect all drives. Make a note of your username and hard drive name. Write down any essential information like passwords stored in keychains and product serial keys.
    2: Stick the 10.6 installer disk into the machine and reboot holding the c key down. Second screen in choose Disk Utility from the Utilities menu.
    3: On the left select the hard drive makers name of your internal boot drive (important) then click Erase and Erase... button (if you want to wipe the drive of all lingering data then choose Security Option>Zero all data) when choosing a name for the drive, use the same drive name as before.
    4: Quit and install 10.6, then go through setup, reboot and use the same user name as before. Software Update, install programs from fresh sources (enter any serial keys) Hold Option and click on Purchases in AppStore to redownload (not Lion of course) and then finally return user files to their respective folders on the Snow Leopard drive.
    5: If you have issues with iPhoto, you can right click on the iPhoto Library and "Show Package contents" and in there is a folder with all your originals. Copy them out and delete the iPhoto Library and reboot, restart iPhoto and it should be recreated, which you can then import your copied originals again.
    Note: using the same drive and user name as before, returning files exactly into their respective Music, Documents and Pictures folders like before matches any pathnames some files like iTunes has to the location of your files. If not done, then exclamation points will occur in iTunes when you click on a song. The iTunes Library will have to be opened in Text Edit and all the partial pathnames "find and replace" corrected to repair.
    Optional, but recommended.
    Ideally it's best to first Carbon Copy Cloner the 10.7 internal to another blank external HFS drive before doing the above steps 1-5 as that way you have a copy of everything in case you missed something or you need to hold option boot from the 10.7 clone. The clone can later be erased and used as a 10.6 clone. Or reversed cloned back onto the internal drive or as many external drives as needed. (don't boot a clone on a different Mac, you can access the files though)
    Clones are hold option key bootable, TimeMachines drives are not.
    Note: The above steps are ONLY for Mac's that didn't come with Lion preinstalled. For reverting a factory Lion to Snow Leopard requires other methods.
