Microsoft Project software will run only under a Windows Operating System. While the university fully supplies the Microsoft Project software to you, you are responsible for ensuring your access to the Windows OS. You may accomplish that access by using a Windows PC for your Microsoft Project work. If you use your Mac computer, you must, at your own expense, obtain and install the Windows OS on your Mac and dual-boot. Information related to 'Bootcamp' can be found here. There are several other methods described in the link below, but regardless, you need to buy Windows.
