Welcome to the OS X Apps thread. Listed below are just some apps available to download for OS X, some well-known, some not (I'm pretty sure?). The list isn't definitive or final, so there's definitely room for additions, and all suggestions are welcome. I figured this thread would work similar to the iOS Apps thread, where we throw suggestions, ask for apps, all that good stuff.
This post isn't as expansive as the iOS Apps thread, but I'm sure there's plenty to add.
