How to Group iCal Calendars in Mac OS X Lion
iCal is a memory-enhancing tool found in Mac OS X Lion. OS X Lion’s iCal offers multiple color-coded calendars, several types of reminder alerts, repeating event scheduling, and more.
You can also organize calendars in groups that contain more than one calendar. To create a new calendar group in iCal, follow these steps:
Choose File→New Calendar Group, press Command+Shift+N, or press Shift; then click the + button in the bottom-left corner of the main iCal window.
A new calendar group named Group is created and added to the calendar list.
Give the new group a name by selecting Group and typing a new name.
To add calendars to the group, simply create a new calendar while the group is selected, or drag existing calendars below the group name in the list.
When you release the mouse button, the Personal calendar moves from between the Work and Untitled calendars to below the Family calendar in the Family + Personal group.
Now you can show or hide all calendars in the group by selecting or deselecting a single check box. You can still show or hide individual calendars by selecting or deselecting their check boxes, of course.
Here’s how you might use this feature in your everyday life. You could create individual calendars for each member of your family and put all the individual family calendars in a group called Family. Then you could make all the family-member calendars visible or invisible with a single click of the group calendar’s check box.
If you have a MobileMe account, you can publish your calendars and invite others to subscribe to them by choosing Calendar→Publish. The people you invite receive an e-mail inviting them to subscribe to your calendar.
