Mac OS X
Mac OS X is the most current operating system (OS) running on Mac computers.
WSU students are encouraged to NOT perform major upgrades to the version of OS X on their WSU Macbooks when they received them. Not all current major releases have been configured immediately to work with WSU services, so upgrading may cause issues.
There are many different major versions, but the latest is 10.10 Yosemite and 10.9 Mavericks.
If you are trying to figure out what version you have on your Mac, go to > About This Mac.
