Does it work on MAC?

Sorry, no. It relies on the GNOME desktop enviroment. You may want to look into the Mozilla Callendar.

I use Evolution myself, and I find it very helpful in many aspects. It has integrated calendaring and tasks which make it usefull for remembering appointments and your to-do list.

I only wish I could sync it with my Yahoo! information. Anyone here want to write such a thing? :p
