Re iCal:

On the far left of the calendar screen is a list of "calendars" with one list entitled iCloud and the other "On my Mac." That was until yesterday. I must have done something without knowing about it but the "On my Mac" list of calendars is no longer there. I've tried everything I can think of but to no avail. I was also having some trouble with the calendar getting synchronized or sent to my iPhone but that seems to have been solved. Thanks in advance for any help offered.
