MacOS Big Sur will be available this fall as a free software update. Our development team is working hard to make Mailbutler compatible with macOS Big Sur (11.0).
You can now sign up to the Mailbutler beta testing program to test Mailbutler for macOS Big Sur in a “real world” environment.
If you sign up, we will notify you as soon as the first Mailbutler version for macOS Big Sur is ready for testing.
You can sign up for the Mailbutler beta testing program here.
