Choose visible calendars
Open Settings → Calendars. Turn individual calendars on or off and star the default used by new events. Visibility changes what appears in normal views; it does not delete or unsubscribe from the calendar.
Assign a local color override when the provider’s color is hard to read or controlled by an administrator. The change belongs to InstaCal and does not alter the provider.
Set calendar order
Open the Order control and drag calendars into the sequence that matters to you. Events that begin together follow this order across the agenda, month grid, all-day and multi-day bars and widgets.
Accounts can be moved too. The ••• button beside an account heading offers Move Account Up, Move Account Down and Sort Calendars Alphabetically. One order serves the whole app, so moving an account here also moves it in every calendar picker and in the reminder-list sort. Reminder lists have the same controls and their own Sort Lists Alphabetically.
Show All / Hide All is one button in the calendar list: it reads Show All while anything is hidden and Hide All once everything is showing, so clearing or restoring the whole list takes one click rather than a tap per calendar.
Create a Calendar Set
Open Settings → Calendar Sets, add a set, name it and select calendars across Apple, Google and Microsoft accounts. Common sets are Work, Personal and Family.
Switch sets from the panel footer or calendar controls. The change updates the whole visible schedule in one action.
A set can also carry its own calendar arrangement, so a Work set can lead with the work calendar while Settings → Calendars keeps its usual order. Use the up and down buttons beside a calendar inside the set. That order applies only while the set is active, and — because calendar identifiers differ from device to device — a set's arrangement stays on the Mac it was made on rather than travelling with your other settings.
Use a set in the menu bar
Under Settings → Menu Bar → Next Event, choose a Calendar Set to limit what can occupy the menu bar’s next-item area without changing the rest of the app.
Connect a set to Focus
Enable the set for Focus Filters in InstaCal. Then open the system Settings → Focus, select a Focus, add an InstaCal filter and choose the set. While the Focus is active, InstaCal shows that calendar scope and restores the prior selection when it ends.
