View reminders as lists or columns on Mac
On your Mac, you can view a reminder list as a long list or with columns for the sections in the list.
Note: All Reminders features described in this guide are available when using updated iCloud reminders. Some features aren’t available when using accounts from other providers.
In the Reminders app
on your Mac, select a list in the sidebar.You can’t choose column view for the standard Smart Lists or when viewing a group of reminder lists.
Do one of the following:
View as a list: Choose View > as List.
View as columns: Choose View > as Columns.
When you view a list as columns, note the following:
If the list doesn’t have any sections, all reminders are listed in a single column with the heading “Others”.
If the list contains reminders that are not within a section, they are listed in a column with the heading “Others”.
