Apple Calendar Comments

The Quick Event feature actually works really well

Positive Comment by OmgItsTheSmartGuy
about Apple Calendar Dec 2011

iCal does a pretty good job of recognizing normal sentences when you add an event through the Quick Event feature. In case you're unfamiliar, Quick Event is a feature that lets you add an iCal event by typing a single sentence.


If you need to at an event quickly, and you don't have too many details, then Quick Event is really great.


I like the leather skin

This is the de-facto calendar for Mac, and it's really nice and easy. However, I still miss Google Calendar synchronization in an easy and fancy way… On the other hand, integration with Apple's Mail is pretty handy.
