Do Not Install Mac OS 10.10 (Yosemite) Operating System

The IT Department is nearly finished upgrading all agency computers to Mac OS 10.9.5. With the assistance of a small group of staff members, we will begin testing the Mac OS 10.10 (Yosemite) operating system in the hopes of making this upgrade available to agency computers at a later date. Until we’ve determined any potential compatibility issues, we would like staff to refrain from downloading the Yosemite installer from the Mac App Store. We’ll share more information regarding Yosemite when the IT department determines it is ready to work with all of our Macs and our wide range of specialized software.
