How do I go from Mavericks back to Snow Leopard

I updated my late 2009 MacBook Pro to Mavericks as I thought the system efficiency upgrades the new OS tauted would be good, but alas my computer is super slow for ALL functions.  I won't give details, because now after the fact, I'm learning others have had this problems.  I don't have time to hope it will improve, I want to go straight back to Snow Leopard and will wait for Mavericks to have more updates, improvements and better reviews on speed.
Technical question on how to go back/ reinstall Snow Leopard? 
First my stats:
I have 2 partitions on my MacBook Pro: 1. my usual use 400gb partition, which was on snow leopard and went up to Mavericks, and 2. 100gb "test" partition running 10.6.8. 
I have an external backup hard drive with Time Machine backup of the 400GB partition.
There was an apple support article - http://support.apple.com/kb/PH14176 - that said to revert to previous OS you simply:
Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
Select “Restore from a Time Machine Backup,” then click Continue.
Is this indeed going to work for me?  Or will it delete the 2 partitions? 
Or do I pull out the Snow Leopard install disc and launch Disk Utility and erase the partition drive and install snow leopard that way?
Would like some confirmation on the best way to go before proceeding, but hoping to tackle this right away.
Thanks!

Here is teh entrecheck report.  Can you advise on any issues or items that defeinitely and easily can be addressed?  Is there anything here that could be causing the tremendously slow, nearly not function computer with Mavericks (I feel like I'm back in the days of OS9), which was FINE on Snow Leopard?

One other issue that concerns me.  I launched Activity Monitor because the computer was so slow and it shows the "memory used: 3.99GB" out of "Physical Memory: 4:00GB" seems like it is being used up (though Entrcheck may be giving different information), which doesn't make sense as I wasn't running too many, and not energy/memory hogging programs (i.e. just Mail, Contact, Safari, & OverDrive).
Any thoughts on this?

  • How do i go from lion back to snow leopard

    I have a HP Officejet 8500 printer/scanner/fax and since I've upgraded to Lion OS X 10.7.5 I can no longer scan from my computer like I did previously.  I don't know if it was a previous version of Lion or Snow Leopard.  If I can downgrade from 10.7.5 to see if that will scan, that is my first choice.  If not, I'd like to go back to Snow Leopard.  I am using USB instead of wireless.

    Those models usually have custom drivers you need to install as it also includes software and the upgrade wiped it out.
    Check the HP website and search for drivers for your model/OSX version and install it.
    If you want to downgrade (upgrade ) to Snow Leopard anyway, this is how to go about it.

  • How do I upgrade from Lion back  to Snow Leopard?

    I had a Macbook Pro that after 3 trips to the shop, Apple finally replaced with a new machine.  Unfortunately the new machine came with the most suck *** operating system ever developed.  It is enough to make me think about going back to Windows.
    The first one is the annoying security feature that many users have complained about, namely that opening any type of file from the internet generates a warning.  I have tried using the terminal command with limited success but in the end I still have to give permission to open up each file and in a file with 500 photos, that is completely impractical.
    The second one involves Preview denying me permission to view files.  I have loaded numerous .jpeg photos (from my camera, that I took,) onto my computer and if I try to open them in preview, it denies me permission even though the permissions list me as being able to read and write that particular file.
    I have been to the Apple store several times with this problem and each time, they claim they either know nothing about the problem (i.e I am the only one who has encountered it) or they just shrug and say it is a Lion improvement.
    So my question is, does anyone know how to fix these problems or better yet upgrade to Snow Leopard which did not have these problems but can no longer be downloaded from the Apple Store?

    Snow Leopard never could be downloaded from the Apple Store, you will have to buy it on disc.

  • If I downgrade from Mavericks back to Snow Leopard and external HD's to be recognised?

    I have had to reboot the system before after a problem but over the course of time since upgrading my iMac has been just unbearbly slow.
    I have tried so many ram fixes but none are working. I am saving up for a new mac but in that time I will need this one to be functioning properly.
    One thing I noticed when OSX re-install was some of my HD's were not recognised. Can this be altered?
    Thanks

    I would first install SL on an external drive, boot from that drive, load all your software and see if all the drives are recognized. Keep it as your startup disk for a few days and if all works well, clone the external to the internal.

  • I reformatted from lion back to snow leopard how do i get my music back i have it on my iphone and when i sync up i still do not have my music on my mac how do i transfer it back to my mac

    i reformatted my mac pro from lion back to snow leopard how do i get my music back. i have it on my iphone and when i sync up i still do not have my music on my mac how do i transfer it back to my mac.

    Wow, you didn't make a backup of your files first?
    You shoudl have come here first for help before doing that.
    https://discussions.apple.com/message/16276201#16276201
    All I can say is make sure you have the same account name on the computer like before, even if you have to create a new user under System Preferences>accounts, then log into your itunes account with that and try to reverse sync from the iPhone like you would normally.
    Apple doesn't expect one to go backwards, so they are not all that friendly, you may have to ask around on MacRumors for third party software that can reverse sync from iOS devices.
    Good luck

  • How do I switch from Mountain Lion to Snow Leopard?  New used computer that I don't have anything on yet but has Mountain Lion installed.

    I just puchased a used 2008 MacPro 2.8 ghz 8 core and it has Mountain Lion installed on it.  I want to go back to Snow Leopard because it is a better stable OS for using Final Cut Pro 7.  I just bought the Snow Leopard Discs to install.  I need to erase the hard drive and install Snow Leopard.  Any help on how
    to do this?  Thank you.

    Downgrade Lion/Mountain 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.
    If you have Snow Leopard Time Machine backups made while on Snow Leopard, then you may 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/Mountain Lion files.

  • IPhoto 9.1.5 won't open, downgraded from Lion back to Snow Leopard

    I have tried to open iPhoto and every time I get a similar error window like I have pasted below.  I have reinstalled iPhoto from iLife '11 disc.  I have updated until I get the message that everything is up to date.  I can't help but think that priviously installing Lion and then going back to Snow Leopard has had something to do with this.  I also go to "Finder>Pictures>iPhoto Library" and there is nothing there.  No arrow saying there is something inside, no list of folders titled with what roll or event they belong to.. nothing.

    This has affected a number of people who reverted from 10.7 to 10.6. Iphoto is missing some background framework that it needs.
    "Library not loaded: .../Versions/A/CoreMedia
    ...Reason: image not found"
    A reinstall may help:
    To re-install iPhoto
    1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
    2a: On 10.5:  Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
    2b: On 10.6: Those receipts may be found as follows:  In the Finder use the Go menu and select Go To Folder. In the resulting window type
    /var/db/receipts/
    2c: on 10.7 they're at
    /private/var/db/receipts
    A Finder Window will open at that location and you can remove the iPhoto pkg files.
    3. Re-install.
    If you purchased an iLife Disk, then iPhoto is on it.
    If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
    If you purchased it on the App Store you can find it in your Purchases List.
    However, if that doesn't help - and in the case of Core Media I wold have my doubts - you'll need to reinstall the OS.
    I also go to "Finder>Pictures>iPhoto Library" and there is nothing there.  No arrow saying there is something inside, no list of folders titled with what roll or event they belong to.. nothing.
    This is normal. Since iPhoto 7 (iLife 08) the old iPhoto Library Folder is a Package File. This is simply a folder that +looks+ like a file in the Finder. The change was made to the format of the iPhoto library because many users were inadvertently corrupting their library by browsing through it with other software or making changes in it themselves.

  • Trying to downgrade MacBook Pro (13" mid 2010) from lion back to snow leopard. Error: you have install Mac 23.1

    Upgraded to lion, thought it was going to be the hip new thing but I can't stomach it. Time to go back home.
    The problem I'm having is that I can't run the snow leopard disk no matter how hard I try.
    I tired booting to the cd and I got that pleasantly multi lingual message telling me "you must restart your computer"
    I wrote the disk image to a USB and got the same massage when I tried to boot to it.
    When I try and run the disk from the desktop I get the grammatical masterpiece of an error message "you have install Mac os x 23.1"
    My computer is boot camped if that makes a difference at all, and I don't care about my data I have it manually backed up (not tm).
    How I can snow leopard 10.6.8 again?

    First, do you have a backup? If so then you can just boot from your Snow Leopard disc, re-initialize the hard drive and install SL anew, then restore from an older backup (assuming you have one?).
    Clinton
    P.S. You might be able to install without wiping your hard drive. To see, just use your SL disc and try to reinstall. I don't know - I've only gone back-in-time with TM since getting a new Mac with Lion installed.

  • Want to restore from Lion back to snow leopard using my Drobo-Fs.  Lion is my current OS but due to lack of support for powerpc applications I want to go back.  Has anyone done a complete restore from TimeMachine on a Drobo-Fs?

    I tried to do this as follows, 1).  Using the install DVD for snow leapard I booted up the mac, 2).  Went into terminal and mounted the Drobo-Fs.  3).  Followed the usual Restore from steps.....
    It took around 8 hours just to come to the point of actually starting the restored....and then calculated like +1000000 hours to complete the restore.  So I cancelled it.
    Not sure, I mean the drobo-fs backs up data, but can it actually restore(full restore) via TimeMachine is my question.

    I'm about to throw my Drobo FS out the window.  It's performance is so erratic.  Right now the green access light is on continuously, yet there's no IO from my mac.  Since upgrading to LION (and finally upgrading the drobo software), I can't log on to the drobo any more. The drobo app says the unit is healthy. 
    I know that the drobo does internal work from time to time, but there's no way to find out what it's doing. No user feedback at all.  Thank goodness I only use it for regular backups and not time machine. Time to move on.

  • 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 do I go back to Snow Leopard from Mavericks (10.6.3 from 10.9.4)

    How do I go back to Snow Leopard from Mavericks (10.6.3 from 10.9.4)

    No easy way.
    If you have no backup of your previous system and data, you basically have to erase your  Mac's internal hard drive and install OS X Snow Leopard from scratch as a clean install and run all software updates as well as reinstall all of your applications and any updates.
    You will now need some way of backing up all of your important data. Backup data to CD/DVD, large capacity USB flash drive OR an external hard drive.
    If you have/had an external hard drive with a complete, copy (cloned ) backup of your previous system, then the doing is/was a lot quicker and simpler.

  • How do I revert from Mavericks to Mt. Lion?

    I have tried the suggestions contained in similar threads without success.  My configuration may be causing problems.  Here is my configuration and the pathway I would like to use:
    As shown below, I have a MacPro early 2008 running OSX 10.9.  I have an iPhone 4S running iOS 7.0.3.  I back up Time Machine to an external hard drive and also to a separate internal hard drive that occupies one of the bays on my Mac Pro, but it is NOT the same hard drive on which Mavericks resides.
    Before migrating from Mountain Lion 10.8.5 to Mavericks, I did a final backup of Time Machine to each of the two drives mentioned above.  I then proceeded to install Mavericks 10.9.  For me, this was a mistake.  I normally wait until at least three updates have occurred before moving up to the next OS X offering.  The many flaws I have encountered in the way Mavericks currently operates have funally exhausted my patience and I must revert to 10.8.5.
    I would like to make the change using Time Machine for both the Mountain Lion operating system and all of the applications and documents.  If I were going to reinstall Snow Leopard 10.6.8, I would start by reinstalling the OS using the DVD which I have and then I would restore the apps and documents from Time Machine.  However, neither Mavericks nor Mountain Lion have DVDs.  I believe that they both can be installed by Time Machine, but this is where I run aground. I don't know how to make it happen.  I have tried and have been hindered by popup windows telling me I can't change the Applications.  I can't go on from there. I would prefer to dowload from the hard drive version of Time Machine rather than the external drive for the simple reason that the internal hard drive is faster.  If that is not advisable, I am certainly willing to go with the external drive.  It is my understanding that I can restore Mountain Lion directly from Time Machine along with all of the documents and other stored items such as Applications, Library, etc.
    I have tried to do this, but can't seem to get the hang of it.  I need a tutor who knows how to do the job using this path.  Assistance will be greatly appreciated.

    A SIMPLE METHOD FOR REVERTING FROM MAVERICKS BACK TO AN EARLIER OS X VERSION
    There were so many caveats and side issues included on various instructions that didn't apply to me that I thought it was a bit confusing. However, I got the idea that restarting while pressing down the option key would give me access to the Recovery drive. I tried it and it gave me several choices. The top one was irresistible. It says "Restore From Time Machine Backup." I had done full backups using Time Machine to both an internal hard drive on my MacPro and an external hard drive just before installing Mavericks. I clicked on "Restore From Time Machine Backup" and selected the external drive since I wasn't sure that the internal drive would work. The internal backup drive is faster, but I felt the external drive was a safer bet. A window came up asking me to choose which backup I wanted to use. I picked the one I made just before installing Mavericks and it went to work. It took a couple of hours to finish, but as it restarted and Mountain Lion 10.8.5 appeared on the screen, I was totally relieved. I feel liberated. Everything works. No wacky glitches to say "gotcha!"
    When you consider all of the written instructions, many of which are very difficult to follow, this very simple method of restoration is amazingly easy. I hope it helps others who are considering moving to OS X 10.9. Just get a good external Time Machine backup of your present system before you venture.
