Darwinports, howbrew, fink, stack, haskell platform... They all work pretty well. BTW FWIW there is even a rather nifty (though learning oriented) Mac specific GUI version: http://haskellformac.com/. Source: over 1 year ago

But ultimately keeping two sets of tooling (well really there were 3) was expensive. So now everyone is on GHC. And that meant beginners had to deal with a much more complex library structure and all sorts of tools to manage complex libraries. Which for non-professionals was a downgrade.

StackEdit[0] pretty much perfected what I needed out of a markdown editor - I just need somewhere to write my tickets/docs that wasn't Github so that I could format it properly while writing. I still use it from time to time [0]: https://stackedit.io/. - Source: Hacker News / 12 months ago
