macOS Sierra is just around the corner, and if you're running the beta or developer seeds of it you're of course going to want to know if your favorite application, Acorn 5, is compatible with it.
And it is of course.
Update August 1st, 2016: Apple has fixed this bug in beta 4, and we are no longer aware of any issues with Acorn and 10.12 Sierra.
If you're running the Sierra betas and you encounter any crashes, bugs, or other issues let us know right away! We want to make sure we don't miss anything.
