The default view on the Mac Calendar app can be by day, week, or month, but sometimes having everything just shown in a single list is more useful. You can do this by using the result of the search system in Calendar. Follow these steps:
Open the Calendar app. If you only want to list from certain calendars, select them in the list on the left. Click the search box in the upper right corner of the app. Enter "" and press return. All events in the selected calendar(s) should be shown as a list in date order.
