OSX Upgrade and Installation

The newest version of OS X is a free install to all Macs that meet the minimum requirements.

Most Macs will meet the minimum requirements and it is safe to attempt the upgrade. If the Mac does not meet the minimum requirements then it will let you know and not proceed with the upgrade. 

Before you begin the upgrade, make sure all your data is backed up. ITS recommends using Apple's Time Machine, a feature built into all Macs.

A fully-automated Self-Service option is now available.

Note: If your Mac is on an unsupported version of OS X you may request an upgrade without charge. 

Directions:

  • The Mason-owned Mac must be enrolled in Casper. To enroll go to: https://casper.gmu.edu:8443/enroll, login with your NetID and Patriot Pass password. Follow the instructions to download and install.
  • When the enrollment is complete the Self-Service app will open and prompt for your NetID and Patriot Pass password. Once you login you will see the software that is available to you.
  • The latest version of OS X will be available for you to download and install. Before running the upgrade, be sure you have a backup of your data, we recommend using Time Machine on an external hard drive.
  • Once you run the upgrade, your Mac will reboot. Depending on the speed of your Mac, it may take up to an hour to complete.
If you have any questions, please contact the ITS Support Center at 703-993-8870.

A Full-Service Option is available at a cost of $30. A technician will install the operating system for you, at the cost of your department.
