Which program is good for planning/managing events? (For mac)

So, this tuesday I’m attending this Event Workshop.
Basically it’s about learning about the process of making/managing events, with everything from booking music, a place, a date, food, and well, everything! (and ends up with as having to decide on an event, plan it and well, have it live out!)
So, I was just wondering, can anyone recommend a good program that helps with managing all that? For mac.
Thanks!
