How do I revert back to snow leopard from lion?

Look above at my original post:
Downgrade Mavericks 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.

Mail data from OS X Lion to revert to format for Snow Leopard

I have to remove Lion and reinstall Snow Leopard on my 2009 MBA. I recall that mail was re-configured when I had upgraded to Lion previously. So, how can I reconfigure mail to work with Snow Leopard again?

IIRC, you needed to export it when in Lion, then import it when in SL. If you failed to do that, you'll have to wait for a Mail maven to pop in.

How to revert to Snow Leopard from time machine on Yosemite Device.

Hello everybody,
Essentially I need to revert back to OS Snow leopard on my new macbook that has Yosemite installed (bought secondhand) as a few of my DJ programs (Rekordbox) are not co-operating with the new OS. I have the back up on a hard drive made with Time Machine, is there any way I can do this?
My old Macbook pro is still working, its just the backlight has gone out, so I have to use a torch on the back to see what I'm doing. Everything still functions correctly on my old device, and I can use the carbon clone copy if need be. Really just need my old laptop's os/files on this new device with Yosemite on it.
Thanks in advance.

Do a backup, preferably 2 seperate ones.

If you do revert, I'd use Setup Assistant to restore your data. This process takes a while, so do it when you won't need the computer for several hours, based on my experience.

How do I revert to Snow Leopard?

My other half has just installed Lion and did not realize that his MS Office and other software would not work. Naturally he has no backup so how do I go about reverting his machine to Snow Leopard?

In Apple Mail pull down File > Import Mailboxes. This will open a dialog with one of the options being MS Entourage. I don't know what the process looks like from there since I've never imported from Entourage but this may be a solution for you. Although the dialog does say Entourage will launch, so it may not work. Worth a try, though.
The process isn't always perfect, and can take a while depending on how much email and other data is in there. However, there might be reason for using Entourgage/Outlook rather than Apple Mail/iCal/Address Book. Certainly another option worth considering though.
I have migrated many users down this road and can tell you that there can be a world of hurt at the end if there are any issues with the main identity, (and being Entourage there are always issues with the main identity, unless you've only been using Entourage since yesterday, or less)
Sadly, I've found this to be the case. If you can manage without Entourage/Outlook it is probably better to do so. What better time to make the transition?

How can I get Spaces in OSX lion to look like Spaces in OSX Snow Leopard

I bought a new MacBookAIR. Used time capsule to import all my settings. Perfect!
However, the new setup of Spaces, is beyond annoying and absolutely unable to work with.
Does anyone know how to get the classic view of Spaces back in OS Lion?
I loved working with that. The active programs were very easy to remember since they had their own 'visual space reference' (upper left, lower right).
Now you only have a row, of which you need to remember which screen is on what number of the row and you now need to swipe through all the d..mn pages instead of navigating intuitively to a specific part of the screen (middle left, lower right etc).
I absolutely hate the new setup and hope somebody has an answer to this....I certainly hope, as an Apple fan, this solution comes quick..for one of the most beloved features now is pretty much dead to me..
Thanks all!

I have installed to Mountain Lion and have the same problem.... I'm content about many things in Mountain
Lion, but lack of Spaces frustrate me.
Since you upgraded, you can downgrade.

Can I restore the Snow Leopard version of 'Preview' for use in Mountain Lion?

When running Snow Leopard I enjoyed using Preview with my HP C7280 All-in-One Scanner/Printer. I could place several items on the glass plate and Preview would then carry out a "preview scan". The superior edge detection software contained in Preview would recognise that there was more than one item on the scanner glass and put a marquee rectangle around each object (even separate images in a magazine page). I could de-select objects if I wanted to at this point to avoid scanning them, or I could opt to scan.
Preview would then scan all selected items in one go outputting a separate file for each one. No need to re-scan and select the next object. Preview would do the lot in one go! This was fantastic for saving time for me.
Preview really 'kicked the crap' out of my PC at work. The best the scanning software on the PC could was to auto-detect a single item.* So if I have a lot to do, I have to preview scan and then save/scan each item individually to achieve the same result.
All this changed when I updated from Snow Leopard to Mountain Lion. The scanning is nothing like as effective and time saving as before. Preview just scans the whole glass plate straight to a file irrespective of what is on it, no preview scan and no object edge detection whatsoever; not even a single object like on my old PC at work. Absolute rubbish!
I really want to restore the functionality I had before. So I wonder, is it best to revert my iMac to Snow Leopard, or can I achieve this another way? I don't necessarily want to abandon Mountain Lion - but I will if I have to.
Is it possible to restore the Snow Leopard version of Preview whilst keeping Mountain Lion? Or maybe download the Lion version from somewhere instead - assuming that the Lion version still has same functionality as the Snow Leopard version?
*Even this is better than what Preview does since I updated to Mountain Lion

It's either that or finding other software for your scanning needs. For example, Image Capture comes with OS X, VueScan 9.2.09, ExactScan Pro 2.24.
Alternatively, partition your hard drive and install Snow Leopard on another volume.
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive. Use the Snow Leopard installer DVD to install Snow Leopard on your new volume.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.

Can't open or start new projects in Logic after updating to Snow Leopard

I've been having a few problems with Logic 9 since updating to Snow Leopard (10.6.8 ) a couple of days ago.
Every time i click on "new" and try and start a new project - logic freezes and i get the rotating circle sign and Logic stops responding - eventually i need to force quit and start again.
Existing projects seem to be functioning fine, although slightly slower than before.
Does anyone have any fixes for this?! Not being able to start a new project is quite a big problem!
Thanks

The mistake was trusting only TimeMachine as your backup/restore.
If you had your users files also backed up to a external storage drive, or used a bootable clone (since they can be directly accessed) then you could have recovered just your files.
This is what I suggest you do since TM apprantly botched things.
1: Visit my user tip here and attempt to fix Snow Leopard in place, the purpose here is to get a booing machine so you can use a working Admin account to copy the user folder containing your files to a regular external drive.
I suggest #8 and #6, this will reinstall OS X over itself to fix it, then reset the User Password so you can hopefully log in.
..Step by Step to fix your Mac
2: This method will also work, you install Snow Leopard onto a extenral drive and boot from it. This is probally a more safer choice than above, it's certainly less work, but it needs a blank external powered drive.
.Create a data recovery/undelete external boot drive
3: Once a copy of your users files is off, then your free to revert your machine back to Snow Leopard.
The ENTIRE drive must be selected and erased, to set the GUID, erase the RecoveryHD and EFI partitions.

Using snow leopard on external hard drive w/Mountain Lion OS Mac

I need to use Snow Leopard in order to use some expensive software that will not work in Lion or Mountain Lion. All of our computers have been upgraded to Mountain Lion, whcih doesn't support Rosetta. I was able to install Snow Leopard on an external hard drive and it boots up fine from another computer (that is not mine) that has Snow Leopard as its OS.
But when I boot up from my MacBook Pro (running Mountain Lion) and from my Macbook Air (also running Mountain Lion), I can't seem to do it. I hold the "option" key when starting and I get the option to start from the computer's HD or from the external firewire Snow Leopard drive. When I choose the Snow Leopard drive, it crashes and gives me that black screen with the kernel (?) message in several languages that I need to hold down the Power key to turn off the computer and reboot.
How can I get my MacBook Pro or my MacBook Air to boot up from the Snow Leopard external hard drive? (Once again, it DOES work with a Mac that has Snow Leopard as its OS).

You can't if the Mac is a Late 2011 and later, perhaps if it's a Early 2011 (as some came with 10.6 and some with 10.7) and it should be possible for all Intel Mac's earlier than Early 2011.
Also, like what has occurred in the past, Apple does eventually issues a firmware update in later OS X versions so that earlier OS X versions, despite the Mac previously being able to boot from them, won't any longer. However far as I know Apple hasn't done this quite yet, but will one day.
Baring those issues, if you installed 10.6 on a external drive using a machine specific black/gray disk from another Mac, it has hardware drivers for that model/year of Mac only.
If you used the 10.6 white retail disks from Apple, it only has hardware drivers for all previous Intel Mac's that came originally with 10.6.2 or earlier from the factory. Mac's with 10.6.3 or later on the drive from the factory have different hardware drivers, thus not on the 10.6.3 white retail disk.
To find out what OS X version came on your machines, use the free MacTracker and use your model indentifier in the Apple menu More > Info (aka System Profiler)
So for those Mac's that originally came with 10.6.3 or later, machine specific disks must be gotten from Apple, or if your really talented, it's possible to create a univeral 10.6-10.6.8 install disk by combing the 10.6.3 image with the 10.6.8 combo update which will boot on any Intel Mac if the firmware permits and the hardware drivers are compable.
There is a method to bypass the firmware and install on Mac's that are Early 2011/Late 2011 via Target Disk Mode, or via taking the drive out of the machine as some Late 2011's use the same hardware drivers as the Early 2011 machines (only a processor bump basically)
How to revert your Mac to Snow Leopard
For the MacAir, you can install 10.6 via a USB thumb drive, of course provided it has the hardware drivers.
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
So in your case you likely should be rather looking at running Snow Leopard in a virtual machine program in Mountain Lion, which MichealLax over at MacRumors has perfected a technique.

Your machine is likely too dated to run 10.8 at all , or if it does will run slow.
It won't run your PPC based software or hardware drives for external hardware.
10.6 will run your PPC software and likely is best for that machine performance speaking, Software Update to 10.6.8 and stay there.
You better do your research first.

How to revert your Mac to Snow Leopard
However I don't use Mail, so I don't know how you can bring back the emails to 10.6.
Sometimes you can redownload them from the server again, or perhaps you can export the emails out of 10.7 mail in plain text or something and save them as text files.
If you use Mail to show the headers too, then "select all" and copy and paste (a lot of work)
Another method would be to swtich hard drives, put a new one in the machine and install 10.6. fresh on it.

How to erase and install Snow Leopard 10.6
Take the old internal drive and put it into a USB enclosure with it's own power supply (or cheaper SATA to USB adapter), you then can hold the option key down and select the 10.7 drive to boot from to access the old emails in Mail like before.
BTW, I totally agreee with you about 10.7 and 10.8.

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.

I get an error message when tryin gto access the mac app store from my apple menu and any browser. I want to upgrade to iMovie '11 from '09. I also want to upgrade from snow leopard to lion.

Depends upon your machine if it can handle Lion or not.
Did you read the minimal specs? 2GB of RAM and a Intel Core 2 Duo (not Intel Core Duo) it really needs 4GB of RAM.
I don't advise any machine that came with 10.5 originally to upgrade to Lion, it's just too much for that older hardware and 10.8 is coming out very soon and that will not run on a lot of older machines so your behind again and having to buy all new software.
As you should know, your investment in PPC based software and hardware drivers for third party machines is not going to work in 10.7.
http://roaringapps.com/apps:table
Perhaps you might want to wait for a new 10.8 or 10.9 machine.
If your sure about Lion, I highly advise making a bootable clone on a blank external drive first, makes it a cinch to come back to Snow.
Or at least disconnect your TimeMachine drive so it stays on 10.6, then you can erase from the disk and restore from TM.

Will updating from Snow Leopard to Lion mess with Garageband 09?

Hey guys, I just bought some software that requires OS X 10.7.5 so I need to update my Macbook pro if I want to be able to use it.. I just fear something happening to Garageband. Does anyone know if it'll mess with anything? I'd prefer not having to update to '11.

Your previous 10.6 based software may not work in 10.7 because Rosetta was discontinued in 10.7
http://roaringapps.com/apps:table
My advice, given the way your talking shows your age, is not to do anything, just software update and remain on 10.6.8.
maintain your backups, because if you jump to 10.7 your going to have issues and software you have installed is not going to work and your going to want to go back to 10.6
I've written a guide, but I don't think you can follow it.

10.8 is coming out very soon, so wait for that and get it (or 10.9) on a new machine next time.
Your a very basic comptuer user, upgrading the operating system is a sudden drastic change and many problems can arrise which you won't know how to fix, you'll have to pay someone to fix them.
So why do that and have to buy all new software?
Apple makes it seem it's easy to upgrade the OS, but when software no longer works they don't care.
