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.

Boot Mavericks and Snow Leopard

Is it possible to have Mavericks and Snow Leopard installed and working on the same workstation?
I have three disks and VMWare Fusion already on my machine. I want to run a bunch of hardware/software no longer compatible on Mavericks.

If your Mac Pro can run both Mavericks and Snow Leopard and you install them on different partitions or different drives in your drive bays, you can run them both, just not at the same time. If you mean as virtual machines, you can do that too, though you'll need Snow Leopard Server for the VM. Check out the Fusion forum for virtualizing details.

I recently upgraded to Mavericks from Snow Leopard. Does Snow Leopard still exist on my Mac? If so, is it possible to restart under Snow Leopard in order to run PowerPC apps? If not, is there an OS available in 64 bit that supports PowerPC apps? Mav ***.

The only reason I upgraded to Mavericks was because my Snow Leopard OS was 32 bit, which I was told would support only 4GB of RAM.
That wasn't quite right. You can put in as much RAM as your Mac's hardware supports. The division is in the apps themselves. A 32 bit app can't use more than 4 GB or RAM. A 64 bit app can use much more.
For example, as a 32 bit only version, Photoshop CS3 can't use more 4GB of RAM, no matter how much you actually have installed. CS4 or later can use all the RAM you want to throw at it.

Upgrading to OS X Mavericks from Snow Leopard

Hi, I am upgrading to Mavericks from Snow Leopard and after I downloaded the OS X from App Store, my MacBook Pro restarted automatically but unfortunately I am stuck in a grey screen with the apple icon in the middle and with the loading wheel turning underneath the apple. It's been so long as around 2 hours that I'm stuck in this screen. Can someone help me please??

kevbon83,
if Mavericks installed successfully, then it should have created a recovery partition on your internal drive. Are you able to hold down a Command key and the R key while booting, to see if it starts into the recovery partition? If that doesn’t work, then you’ll need to use the original model-specific grey installation DVDs that came in the box with your MacBook Pro. Put the disc marked “Mac OS X Install DVD” into your internal SuperDrive, and reboot while holding down the C key. You’ll then be able to run the DVD’s Disk Utility command to “verify” your internal drive.

HT201364 Unable to update to OS X Maverick from Snow Leopard 10.6.8.

Unable to update to OS X Maverick from Snow Leopard 10.6.8. I have 648GB available on my MAC HD but when I go to install I get error that I need 2 GB free and 8 GB available. Does the AppStore install some where other than the MAC Hard Drive on my imac?

The reference is to RAM. You need at least 2 GBs of memory installed.
OS X Mavericks: System Requirements

I want to install an old airport express, the ones which are directly plugged into the socket - but it does not work with Maverick or Snow Leopard - can I configure it with a windows pc?

I want to install an old airport express, the ones which are directly plugged into the socket - but it does not work with Maverick or Snow Leopard - can I configure it with a windows pc?

The Mac running Snow Leopard should be able to configure virtually any version of the AirPort Express.
Tell us what steps that you are taking to configure the Express and what happens after each step.

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 do I Uninstall OS X Mavericks & reinstall Snow leopard?

I want to uninstall OS X Mavericks & reinstall Snow Leopard. Mavericks has disabled iPhotos & some other software I use daily so I want to get rid of this new OS. Anyone know where to start? I can't seem to find my way around this new OS. Thanks.

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.

Will upgrading on to OS X Mavericks (from Snow Leopard 10.6.8) affect the running of the installed 3rd party softwares/programs?

I have just received an email encouraging me to upgrading on to OS X Mavericks (from Snow Leopard 10.6.8). Currently I do have in my computer several 3rd party software and programs (from Adobestuff, finalcut Pro, MS Office, ILife etc.
Will upgrading to OS X Mavericks affect the running of these software /programs? Will I need to also upgrade these softwares?

There may be issues with compatibilty, as with any OS upgrade. Snow leopard (10.6.N) includes a piece of software from Apple called Rosetta. This software allows older PowerPC applications to run on Intel based Macs. This software does not run on any OS X higher than the latest Snow Leopard, 10.6.8. You can see if you have any of programs that require Rosetta installed by bringing up the "System Information" application through spotlight (click on the magnifying glass icon on the upper right, type System Information in the search field and select the application thta is found).
Once in System Information select "Applications" under "Software" near the bottom of the list. Scroll through the list of applications and if any indicate that they are PowerPC based then they will not run under Lion, Mountain Lion or Mavericks.
Hope this helps.

I upgraded to Maverick from Snow Leopard.

I upgraded to Maverick from Snow Leopard. Since the slowness problem is that I don't have enough RAM, how do I get my MacBook Pro back to Snow Leopard?

The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They also have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the minimum. I now have 6GB installed on a machine supposedly limited to 4 GB.

If I upgrade to Mavericks from Snow Leopard will I still be able to use Microsoft office??

Welcome to Apple Support Communities
Only if you have Office 2008 or 2011. Older Office versions are PowerPC apps, so they no longer work with Mavericks.
If you are running Office 2008 or 2011, open any Office app, go to Help menu (in the menu bar) > Check for Updates, and install the latest version.
If you are using an older Office version, uninstall it and install another application:
Upgrade to Office 2008 or 2011 by buying it from the Microsoft website.
Install Apple iWork applications after upgrading to OS X Mavericks.
Install LibreOffice > http://www.libreoffice.org.
Remember to make a backup of your files with Time Machine before upgrading.

After updating to Mavericks from Snow Leopard, everything works except iPhoto. If I buy the current version of iPhoto for $15, will it work on Mavericks?

After updating to Mavericks from Snow Leopard, everything works BUT all my photos were lost. If I buy the current version of iPhoto for $15, will it run on Mavericks?

If you have iPhoto from iLife '11, then I would first install it on your computer. In that way you would be able to get the new iPhoto free since you are running Mavericks.
iWork and iLife for Mac come free with every new Mac purchase. Existing users running Mavericks can update their apps for free from the Mac App Store℠. iWork and iLife for iOS are available for free from the App Store℠ for any new device running iOS 7, and are also available as free updates for existing users. GarageBand for Mac and iOS are free for all OS X Mavericks and iOS 7 users. Additional GarageBand instruments and sounds are available for a one-time in-app purchase of $4.99 for each platform.
The iWork apps are free with a new iOS device since 1 SEP 2013. They are free with a new Mac since 1 OCT 2013. They are also free with the upgrade to OS X Mavericks 10.9 if you had the previous version installed when you upgraded.
