How do i downgrade from mavericks to snow leopard

I have been having a very difficult time with mavericks and would like to do a clean factory restore on my MacBook. I have the disks that came with my device which are Mac OS X Snow Leopard DVD, MacBook Applications Install DVD and the iWorks DVD. I have tried multiple times to erase my drive and do a clean install but for some reason the Applications Install DVD will not load. It keeps giving me error messages. I have also attempted to install any updates that might be available for Mac OS X Snow Leopard and again I receive error messages telling me that the updates can not be installed.
I can get to the point to where Snow Leopard loads, but I am missing many of my programs such as App Store, GarageBand, iMovie, etc that originally came installed on my machine.
Can someone please walk me through how to do this?
All help would be appriciated.
Thanks,
Selena

How do I downgrade from Mavericks to Snow Leopard and save my new pages files?

Unfortunately, the Mavericks system isn't working for me. It's way too slow, has issues with Finder and so on. Basically it's just a pain in my *** and my
beloved Mac Book Unibody (2010) just can't handle it! After searching for hours online for a solution, I'd love to get back to the good old times.
I read that I can downgrade to Snow Leopard with my latest TM backup, using the recovery mode. Problem is that I "upgraded" sometime in October, so I have accumulated a bunch of new files. Being a teacher, I have tons of documents and Apple unfortunately changed all the old '09 files into '13 ones. Will they still work under the new old system, or do I have to find some way to export them into '09 files?
Is it fine to use the TM backup, or is it better to use ds store's method to recover the system?
Thanks

I backed up the system just prior to upgrading.

How do I downgrade from Lion to Snow Leopard without losing iWork 09? I upgraded my MBP from 10.5 (originally 10.4) to 10.6, then again to 10.7. Should I go back to 10.4, 10.5 or just to 10.6?

How do I downgrade from Lion to Snow Leopard without losing iWork 09? I upgraded my MBP from 10.5 (originally 10.4) to 10.6, then again to 10.7. Should I go back to 10.4, 10.5 or just to 10.6? I don't remember which system included iWork 09 and don't want to lose it. Thanks for any help.

Thanks for the information! My sister gave me the MBP for my daughter with Leopard installed. I purchased Snow Leopard and installed it, then my daughter purchased Lion. So I do have all the installers. If iWork wasn't included with any of those, I guess my sister purchased it while running Leopard. I'll have to contact her. Thanks again.

I want to downgrade from Mavericks to Snow Leopard. How can I do this?

I want to downgrade my 2009 IMac from Mavericks to Snow Leopard. Please explain how I do this.

Insert the Mac OS X 10.6 DVD, restart the computer with the C key held down, and install Snow Leopard onto a blank volume. If needed, use the Disk Utility to erase or repartition the internal drive.

How can I downgrade from Lion to Snow Leopard?

Hello.
Yesterday, I upgraded my Mac to Mac OS X (10.7 Lion) from 10.6.8 Snow Leopard. However, I wish to downgrade.
Obviously, I would like to not lose any data at all. However, I have never downgraded before.
I still have the Snow Leopard installation disk that came with my Mac.
How should I do this? I was thinking it would be easiest to simply head on over to an Apple Store...
I did some research (aka Googling), and I read up on the subject quite a bit.
If I simply put in the disk, will I be able to downgrade from Lion to Snow Leopard as easily as the upgrade was?
Also, I have heard about holding down the "C" button to do this... how exactly?
I have never backed up my Mac, nor used Time Machine.
Also, is it possible to install Snow Leopard on a separate disk, and set it up so that I can switch between them on command?
Will all of my preferences be saved, or does this wipe everything, not just the system and libraries folders?
I realize that I have a lot of questions, and therefore I appreciate everyone's help in advance. Thanks again.
Sincerely, Zach

Backup your files.
Booting From An OS X Installer Disc
1. Insert Snow Leopard Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Erase Drive
1. Boot from your OS X 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. Upon completion quit DU and return to installer. Install Snow Leopard. Restore your files after the installation has completed.

Downgrading from Mavericks to Snow Leopard, can't boot from USB drive

I'm attempting to do a clean install of Snow Leopard on a 2010 Macbook. The MB had recently been upgraded to Mavericks, but because it was running slowly, I decided to downgrade. (If you respond to this post, please don't ask me why I'd make this decision.)
As with any other clean install I've done--all pre-Mountain Lion--I backed everything up, I created a .dmg file of the Snow Leopard, and made a perfectly good, bootable USB drive with the OS (1 partition, GUID table); I tested this USB drive on another Macbook, one currently running Snow Leopard, by holding option as I booted up. It works fine and gets to the installation screen.
I booted the Mavericks Macbook while holding command+r, and I erased the main HD. I then formatted it with 1 partition, with a GUID table. All was normal.
But here's where the problem starts. I plugged the USB drive into the formerly Mavericks computer, and held option for the bootloader. It recognizes the OS. But when I click the arrow to proceed, it inevitably has a kernel panic and tells me to restart the computer.
I re-made my bootable drive, and I tested it again on the other machine. Again, it's still fine. Plugged it into my main machine--again, a panic.
Using command+r to reach disk utility, I've now erased and repartitioned the computer's hard drive several times, even using the advanced-security erase feature. Still, the panic.
When I hold command+r at boot, it always forces me through the Internet Recovery. The only option offered to reinstall OS X is with Lion, which I didn't buy with my Apple ID.
What can I do?

Sorry, but this didn't help me. From what I gather, Mavericks (or maybe Mountain Lion) included a firmware update that, for some reason, prevents users from downgrading to anything before Lion. This makes things difficult, because I didn't buy Lion--I made the leap from SL to Mavericks.
Here's the strange part, I learned: When I enter Internet Recovery, I'm prompted to reinstall Lion, not Mavericks. And because I didn't buy Lion, my Apple ID/password, which are asked for, don't help.
Anyone else with suggestions? None of my USB-based installations are working, and I'm feeling out of luck. I don't want to spend money at the Apple store...

Downgrade from Mavericks to Snow Leopard without using Time Machine

Hello.
I upgraded from Snow Leopard (OSX 10.6.8) and upgraded to Mavericks but the Time Machine was not turned on. Is there anyway to downgrade back to Snow Leopard?
I contacted Apple Support and was told that it is not advisable to format the drive and do a clean install using Snow Leopard installation Cd's since Mavericks made changes to the hardware on the iMac. They advise using time Machine to downgrade, but this option is not available to me. Is this true?? Or can I re-install Snow Leopard with no issues?
Thanks.

You would reinstall 10.6 using your installation DVD.
Out of curiosity, how much RAM do you have? Recent versions of OS X really shine with 4GB or more.

Going from Mavericks to Snow Leopard?

I'm trying to go from Mavericks to Snow Leopard on my 2011 Macbook Air (intel i7, 1.8 Ghz, 4 GB of Ram), but it won't let me. I tried going into Disk Utility and deleting everything off the hard drive itself, then booting from the disc itself, but it won't work. I tried restoring for a Snow Leopard back-up, it would work, although it did let me boot to a Lion backup. I even tried to simply set the start-up disc to my Snow Leopard retail disc, but it wouldn't boot. I could hear the disc moving in my USB superdrive for 15-20 sec, then it just stopped and the computer stays at the Apple logo. Any suggestions?

You cannot run Snow Leopard on that model. You can reinstall Lion which is what came pre-installed from the factory:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

How can I upgrade from OS X Snow Leopard to OS X Lion?

How can I upgrade from OS X Snow Leopard to OS X Lion?

Well Mt Lion is the latest, but if your machine can't do 10.8, then call Apple via phone and order 10.7
However you really need to do your homework first, as a lot of software and drivers could stop in 10.7, no Rosetta like in 10.6, could cost you plenty.
Things to consider before upgrading OS X

How do I upgrade from Lion to Snow Leopard?

Snow Leopard has this great feature called Expose which is a great improvement on Lion's App Expose (and Mission Control).
Can someone point me to the steps I need to take to upgrade from Lion to Snow Leopard?

Written just for you (ok it's a paste)
Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
Disconnect other drives except the backup drive as to avoid any mistake.
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire disk of ALL DATA. (warning, everything will be gone and not recovered, OS, programs, files, Windows etc all gone.)
Note: You might want to hold c and boot off the 10.6 installer disk and use Disk Utility to format the new blank external drive instead of using OS X Lion that's hosed. Then reboot into Lion and copy files, be safer that way perhaps.
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP there, don't install OS X yet.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same drive name as before, and click Erase...
(note: if you want to "scrub" the drive of old files that haven't been overwritten yet, then use the Security Option > Zero Erase, takes a lot longer)
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
http://support.apple.com/kb/DL1399
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly recommended.
A lot of people use a Carbon Copy Clone of their boot drive to a new HFS+Journaled external drive (used only for this purpose) as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.

How do i clean install and Downgrade from Lion to Snow Leopard?

Hello I want to sell my Mac Book. Lion already did not run well. Therefore I want to install snow leopard back on it and I want to wipe the computer. But it does not work. When I start the computer with the snow leopard and hold the c and apple button then there is only a white screen. I cannot delete the hard drive with the regular disc utilities program and apple r also does not work. What do I do wrong? Can someone help me here?
Thank you!!

It's C on start, not cmd (apple) + C.
Is the Snow Leopard disc the original that shipped with the Mac?
The retail SL disc is only 10.6.3 so won't boot any Mac that shipped with 10.6.3 or later.
It is possible to install SL on an external HD and update it to 10.6.8, then boot to it by holding opt (alt or ⌥) on start up and selecting the external from the list. Erase the internal HDD from the external's Disk Utility (select the top line - the one with the manufacturer's name and the size of the drive).
Then use the restore function in DU to clone the SL installation from the external back to the internal.

ICal and Mail don't work after downgrade from Lion to Snow Leopard

Hey everyone, after an extremely awful time with with Lion (it knocked out of my audio interface AND my wireless) I downgraded back to Snow Leopard yesterday. I made a Carbon Copy of my Lion drive with all my data on an external drive (which I still have) and after wiping my local drive clean I reinstalled Snow Leopard from my disk. After it was done I chose to transfer data from another system local system (I selected everything) and an hour and a half later everything was transferred over. After doing a software update, I've found that I get big error messages with iCal, Mail, and even the App Store that say they can't open and I'm assuming that it has to do with incompatible data that got transferred from Lion. Any ideas on how to get those programs back up and running?? Thanks so much for you help!

Indeed the USB issue seems to be related to missing drivers.
You have to install this USB 3.0 driver:

Furthermore you have to ensure that chipset driver was installed too.
The notebook supports ATI graphic chip and AMD chipset. The chipset driver is part of the ATI graphic card driver and therefore you should ensure that this driver would be installed too.
