If you plan on applying the latest update either to prepare for OS X Lion or to address the fixed issues (or both), be sure to fully back up your system using Time Machine or a cloning utility before you do. In addition, you might consider reading our guide to preparing for an OS update, to ensure any permissions issues and other problems are properly addressed before installing the update.

The update is available via Software Update, but can also be downloaded and applied from the following locations:

Mac OS X 10.6.8 Update Combo (1.09GB)--For any version of OS X 10.6

Mac OS X 10.6.8 Update (474.2MB)--Requires OS X 10.6.7

Apple has also released a security update for OS X 10.5, which addresses the same security holes that were patched in this release of Snow Leopard. The security update 2011-004 can be downloaded from the Apple Support Website.
