Fixed button focus issue (M2 Pro / Ventura)
On an M2 Pro machine running macOS Ventura, I discovered that the close button ('X') would be in focus on app startup ... this had 2 undesirable consequences:
- The button looked ugly with a focus ring around it.
- When the Space key was pressed to initiate playback, a button press would be triggered, quitting the app.
This issue has been fixed.
Dropped support for macOS 10.12 Sierra
Xcode 14 does not support building for macOS Sierra.
