Mac OS X 10.6 Snow Leopard operating system changes

Snow Leopard OS X 10.6 has added some enhancements and features that are not immediately noticeable. The enhancements that affect University Applications are listed below:

Exchange Email, Contacts, and Calendar

Snow Leopard has added support for Microsoft Exchange. We recommend that you do not configure an Exchange connection in Snow Leopard until the functionality has been tested and approved by the Exchange Implementation Team.


System files using the new HFS compression format will be restored as uncompressed files, and Web GUI may not start.


Wireless connection to UVic Default and UVic Open are the same for OS 10.6 as previous versions.

Expose and Stacks

There is a new look for Expose and the Dock. Windows are displayed in an organized grid. Folder files are now scrollable.


Snow Leopard comes preloaded with printer drivers. Any drivers that are not native will have to be downloaded from the Printer Manufacturers website.


The new Preview can now open multiple PDF documents, display their contents as contact sheets and show thumbnails.

QuickTime Pro

QuickTime Pro is now included with Snow Leopard.

Touch Gesture recognition

Snow Leopard supports all gestures, no matter what Mac model you have (as long as you have a gesture-capable track pad.)
