Hi there! We have some updates to provide you with regarding
macOS Big Sur 11.0

Painter 2021 (available as both a perpetual and Corel subscription license) is compatible with macOS Big Sur 11.0. and the new Mac models with M1. Other versions of Painter, including the Mac app store edition, are not compatible with macOS Big Sur 11.0 or M1 and can only be used with the versions of macOS 10.x they were designed for. You can find more info about the new Painter desktop product and upgrading here:  https://www.painterartist.com/painter  

The Painter Essentials product line was designed specifically for macOS 10.x operating systems. Unfortunately, it is not compatible with the newly released macOS 11.0 or the new Mac models with M1. We are currently developing future versions of Painter Essentials to take advantage of this new operating system.
