Apple has begun the beta process with macOS Big Sur (version 11).
ClueTrust is unaware of any problems with the current shipping version of Cartographica (1.5.0) and the current Big Sur betas. However, ClueTrust does not officially support the use of Cartographica on unreleased operating systems.
If you encounter a problem with Cartographica and Big Sur, please verify that you are running the most recent (1.5.0) version of Cartographica before reporting a bug. With that said, we do appreciate the reporting of bugs found under new OSes and Platforms, but support times may be longer especially early in the beta cycle.
Thank you for your support!
