Starry Night is not just yet fully-compatible with the latest macOS release 10.15 Catalina.
Starry Night 8 will be fully compatible with macOS 10.15 Catalina.
I will update this post with an ETA when I have a timeline for development.
But, for now, if Starry Night on macOS is important to your daily observing please do not update to Catalina.
Starry Night 7 is affected by this issue as well.
Thanks for your patience at this time.
