The Calendar App Is Better Now
With macOS Sequoia, the Calendar app also received a major upgrade. Now, it’s easier than ever to check all your reminders without leaving your calendar.
When you open the Calendar app after installing macOS Sequoia, you’ll notice all your reminders are there, alongside your other events. All of these will be color coded, so you know exactly what you’re looking at.
You can also create, delete, or edit your reminders. Any changes you make in the Calendar app will be instantly reflected in the Reminders app, and vice versa.
