How can I get CorelDraw on my MacBook Pro?

Install Windows via Bootcamp, it's very easy and its a software that its already installed on your MBP, you just need a Windows installation disc or an ISO image, the drivers (Bootcamp provides it) and more or less an hour of your time. Or run int through a virtual machine software (like Parallels), depending on your Macbook specs I would recommend it or not.

Install Windows then install Corel.
