[kolektiv]

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.
