I have a MacBook Pro with Yosemite. Can I run Knit Design Studio?
No, Knit Design Studio is compatible only with Windows platforms. In order to run it on your Mac computer, try using CrossOver. This is an application that allows you to run Windows programs on Mac without requiring a Windows license. Also, you can try Parallels Desktop, VMware Fusion, or VirtualBox. These applications let you run other operating systems on Mac.
