http://fsharp.org/use/mac/ is probably a good place to start - if it doesn't work for you for any reason, do please complain - the community is really active in trying to make everything better! (The general section on cross-platform development may also be helpful - perhaps more when you've got a little way in!)

Additionally, there's an F# room on http://fpchat.com/ (a Slack group dedicated to functional programming) and you'd be more than welcome to come and ask questions there too - I recommend that venue in particular as it's very active at the moment.

Hopefully that's enough to have a play - reply here if I can help at all too.

To get started on OS X just go to http://fsharp.org/use/mac/

A nice and very good online tutorial to learn the language is http://fsharpforfunandprofit.com/

I wrote a blog post about setting simple fsharp project without monodevelop. You need to install fsharp using brew before read the post.

Thanks, this was really helpful!

As per language Expert F# from Apress by Don Syme et. all is a pretty solid practically oriented introduction. As for how to use the language most Ocaml and ML oriented books should offer hints. F# is a bit more extensive of course but how the language originally appeared it was "Ocaml for .Net".
