This webpage provides information about Mac OS X Lion on UW-Whitewater campus, and includes instructions for the optional upgrade of the operating system on individual University-owned and managed Apple computers, which currently run Mac OS X Snow Leopard (10.6).

Optional OS X Upgrade to Lion (10.7)

The upgrade is available only for individual University-owned and managed Apple computers that meet the minimum hardware requirements, and currently run OS X Snow Leopard. Apple computers in general access computer labs and classrooms on campus will continue to use OS X Snow Leopard (10.6) without change at this time.

Upgrade Instructions

Please note that the OS upgrade is NOT reversible. If you are not familiar with OS X Lion, you may want to consult a separate PDF with a list of top new features first, to understand fully how this change may affect your work, and to decide if you want to proceed. If you have any files located on your computer's hard drive (and not on University network drives), iCIT strongly advises you to securely back up your data before proceeding with the upgrade.

Once you begin the upgrade, you will need to budget approximately one hour (the actual time may vary depending on your web connection and computer speed) for the process to complete. During this time you will NOT be able to use your computer. Once started, the upgrade process cannot be stopped or interrupted.

To begin, on your Mac run the app called Self Service. When the Self Service application launches, in its main window, in the Featured category, you will find Mac OS X Lion. When you are ready to upgrade, close all other applications running on your Mac, click the UPGRADE button next to the Lion icon in the Self Service application, and then follow the on-screen prompts.
