All of our apps have been tested under the forthcoming macOS Sierra and seem to be functioning without problems.
We have released a minor update to Sϵv϶n to make using Sierra tabs easier. It changes the shortcut forto (previously ). In a tabbed window the “+” tab creates a new rich text document, a shift-click will create a new plain text document.
If you discover any macOS Sierra issues with our apps please contact us and we will investigate.
