OpenCourse is not signed with an Apple Developer ID yet, so the first time you open it, macOS says it cannot verify the app. Close that message, open System Settings ▸ Privacy & Security, scroll to the note about OpenCourse and choose Open Anyway. You do this once for each version you download yourself; a version OpenCourse installs from Settings ▸ Updates opens without it.

What's new in 0.7.1

On GitHub

OpenCourse 0.7.1 adds more control over Coach conversations and keeps study timers consistent across windows.

  • Choose a default Coach voice and listen to a short preview before saving it.
  • Customize the shared, voice, background, first-conversation, and follow-up prompts used by new coaches. Existing coaches retain their saved instructions.
  • Keep one Pomodoro timer synchronized across the main app and notebook windows, including after sleep or window reopening.
  • Use the shared title bar and Pomodoro controls in notebook windows.
  • Remove the bundled Neon Afterhours theme. Existing selections fall back to the default appearance; imported themes remain supported.

The desktop database upgrades automatically to support saved Coach prompts.
