Black Hole Puts Your Workday in the Mac Notch
An open-source macOS utility for tasks, focus sessions, notes, and calendars that lives in the notch.
- For
- Mac users who manage tasks and focus time
- Worth noticing
- The app uses Model Context Protocol to let assistants act on a local workday through a secret-token web address.
Field notes
The interface is organized around a notch or a movable external-display button rather than a conventional full-screen dashboard. It combines task rollover, a daily text note that can become tasks with Command-Return, read-only iCloud, Google, and Outlook calendars, and focus summaries covering active days and streaks. An optional Model Context Protocol connection provides a separate assistant-facing address protected by a secret token. The site also warns that current builds are not notarized by Apple.
