birthdayBook
birthdayBook is a personal contact and birthday management app for macOS designed to help users keep track of birthdays, anniversaries and other important dates for family, friends and colleagues. It provides simple contact storage with birthday information, reminders for upcoming dates, and basic organization tools. The app targets users who want a lightweight, dedicated solution for managing important personal occasions without the complexity of a full contact management system.
AI Recommendation
1 suggestionNo public information is readily available about whether birthdayBook has a native Apple Silicon build. The developer's site and recent updates could not be found through standard search channels, which suggests either limited online presence or possible inactivity. If you rely on this app, contact the developer directly at the email or website listed in the app's About or Preferences panel to ask whether a native Apple Silicon build exists or is planned. With the Rosetta 2 compatibility layer being removed in macOS 28 (September 2028), it is important to confirm the app's status sooner rather than later — an Intel-only build will stop launching entirely on that release. As a stopgap, consider alternatives like Contacts (built into macOS, supports birthday fields and notifications), BirthdayReminder, or Occasion — all of which have confirmed native Apple Silicon support and are actively maintained.
