Google Calendar alarm on Mac

A Google Calendar reminder is a banner. If you wanted an alarm, here is the closest thing on a Mac.

People search for a Google Calendar alarm because a notification is too easy to ignore. On a Mac, Google Calendar gives you a notification in the browser or in Apple Calendar, and a notification is a banner that fades. There is no setting that turns it into something that interrupts you until you answer.

Why a notification is not an alarm

The closest thing to an alarm on a Mac

Slapss lives in the menu bar. When the event starts it covers the screen, on every display if you want, with the title, the time and a Join button, and you cannot keep typing until you deal with it. It can also play a sound.

Questions

Can Google Calendar ring like an alarm on a Mac?
Not by itself. On a Mac its reminders are notifications, shown as a banner by your browser or by Apple Calendar. To get something that takes over the screen, you need an app that reads your calendar and does that, such as Slapss.
Can the alert make a sound?
Yes. Turn on Play sound when alert appears in Slapss Settings and the alert comes with an audio cue.
What happens if I snooze it?
It comes back. You can snooze for 1, 5, 10, 15 or 30 minutes, 1 hour, or until the meeting ends. Dismissing is a separate choice.
Do I need to keep Google Calendar open in Chrome?
No. Slapss reads your Google Calendar through macOS Calendar, so the alert fires with every browser closed.
Is Slapss free?
Yes. No subscription, no in-app purchase, no limit. Slapss is open source under the Apache 2.0 license.
