Changelog
What's new in each release.
- Fixed: if you use Slapss with a Microsoft 365 account and haven't given it access to the macOS Calendar app, the menu bar showed your next meeting, but opening it said "Calendar access denied" instead of showing your agenda. Your agenda now appears whenever a Microsoft 365 account is signed in. Access to the macOS Calendar app is optional, and always was.
- Fixed: Microsoft 365 calendars could stop refreshing in the background — while a menu was open, or after macOS put Slapss to sleep. New and changed meetings now arrive on time.
- Slapss no longer asks macOS for read-only access to files you pick yourself. Nothing in the app ever used it. What is left is the sandbox itself, calendar access, and outbound network for Microsoft 365.
- Slapss is now open source. The complete code is published on GitHub under the Apache 2.0 licence, so "your calendar never leaves your Mac" is something you can check rather than something you have to believe. github.com/theshiver/slapss-app
- New Source Code link in Settings > About.
- Fixed: a repeating meeting would stop showing its full-screen alert after you dismissed it once. Every occurrence of a repeating event was treated as the same event, so dismissing one also dismissed all the following ones — while the menu bar countdown kept working normally. Snoozing and hiding from the menu bar were affected the same way, and are fixed too.
- Everything else is unchanged. Same app, same features, still free, still no accounts and no tracking.
- Fixed: Snooze could appear to do nothing on the full-screen alert in macOS 27 beta. The snooze choices now open reliably inside the alert.
- Fixed: Calendars now reappear in Settings without restarting Slapss after you remove and re-add a macOS Calendar account.
- Set your own lead time for the full-screen alert with a simple slider: at meeting start, 30 seconds, or anywhere from 1 to 15 minutes before (Settings > Alert > Show alert). Handy if you need a few extra minutes to walk to the meeting room.
- Busy day? The agenda now scrolls instead of growing past the bottom of your screen. Short days look exactly the same as before.
- The full-screen alert's Join button now follows your color theme, and a small hint shows the keyboard shortcuts that were always there: Return to join, Esc to dismiss.
- The alert now says "Meeting" for meetings and "Reminder" for reminders — previously everything was labeled "Reminder".
- Setup steps are numbered correctly again when optional steps (like Microsoft 365) aren't shown.
- "Nothing soon" in the popover is now clickable — it opens the details of that next meeting.
- Settings got clearer: short explanations under the two lead-time options and the "accepted meetings only" filter, and the Calendars tab now offers a fix when calendar access is missing.
- Dates in the popover header now follow your language's natural word order (e.g. "13 Tem Pzt" in Turkish).
- Small polish: bigger click target for completing reminders, and the menu-bar countdown no longer freezes while a menu is open.
- Fixed: the Preferences window sometimes opened behind other windows. It now always comes to the front.
- Themes! Pick between Sunset (the classic slapss look), Ocean, and Forest in Settings or during onboarding.
- New "Presenting Now" toggle pauses the full-screen alert while you're screen sharing or presenting, so meetings never take over your screen mid-demo.
- Faster access to meetings: a Join button right in the notification banner, Return/Enter to join or dismiss the full-screen alert, and a new "Open in Calendar" button on agenda rows.
- Plus a round of UX, accessibility, and localization improvements throughout the app, and a new menu bar icon.
- New setting to only show the full-screen alert for meetings you've accepted (Settings > Alert). Tentative and declined meetings still appear in the agenda but won't trigger the overlay. Off by default.
- Alerts for meetings whose start was missed by more than 10 minutes (for example while your Mac was asleep overnight) no longer pile up when you reopen the lid.
- Fixed high background CPU usage (~40%) when the popover is closed. Animations now pause when the app is idle.
- Reduced Motion: all animations (blobs, floating dots, pulsing dots, background mesh) respect the macOS Accessibility > Reduce Motion setting.
- Full-screen alert can now be shown up to 1 minute before a meeting starts (Settings > Alert > Show alert).
- About section now shows the app website and support email instead of the developer's personal contact.
- Version number in About no longer shows the build number.
- Welcome tour: language selection is now the first step, so the rest of the setup runs in your language.
- Welcome tour: lead-time picker now includes a 1-minute option.
- Reminders now trigger the full-screen overlay alert at their due time
- Overlay shows a Complete button instead of Join for reminders
- Complete reminders directly from the overlay or from the agenda in the popover by tapping the circle icon next to any reminder
- New setting to turn the reminder overlay on or off (Settings, General, Alerts, default on)
