Apple yesterday released the fifth revision of Mac OS X 10.6 Snow Leopard. Offering a series of updates and refinements over 10.6.4–which was released in June–this incremental update focuses primarily on security and stability. A detailed list of all improvements can be found here. Some of the standout fixes included in the update address performance issues in graphically intensive applications and games, as well as oddities and performance glitches in the UI. The update is available via Software Update in the Apple Menu, or by direct link (see below). Though initial reports have been positive, we always recommend that you perform a Time Machine backup prior to installing a significant OS revision.
