I sent an email with this information but I’ll post here as well.
I wanted to share some information regarding running windows via parallels, particularly to mac users with Retina screen (high resolution) Apple laptops. The mastercam interface will probably appear less than ideal using Parallel’s default setting (if you have a retina display), particularly the menus and interface. You can adjust the way parallels displays windows if you open the configure window from the top menu (see image 1). Under the Graphics option you can change the Resolution to Scaled which will work better with Mastercam. If you are running into issues with mastercam operating in windows on Parallels please let Chris and I know and we’ll try to help.
