Yes, you read that right. No matter what the warlords at Apple may tell you, you can run open source apps even if you are using Mac OS, which itself is closed source.
Wondering why you ought to choose open source? Well, for a start, owning a Mac is an expensive proposition, so opting for open source applications on the Mac is one decision your wallet will appreciate. Second, it is common knowledge that open source applications are updated more frequently, are community-driven, and easily customisable. What more can one ask for?

It is an open source word processor for Mac users, and comes loaded with great features.
AbiWord: Heres yet another open source and totally free word processor.

Audio and video
