Not at this time, no. GoCanvas supports Windows laptops/desktops/tablets that are running Windows 7, 8 or 10. We also support Android and iOS phones and tablets.
A potential workaround would be to use a virtual machine to run the GoCanvas Windows client on a Mac system. A virtual machine is a piece of software that allows you to install Windows and other operating systems on your Mac desktop. Click here for more details on using a virtual machine.
