There is also now the Mac OS X Strike Force that aims to improve using Haskell on OS X.

Haskell Platform is a Haskell distribution with batteries included. This is a generic distribution of the Haskell Platform. While it should work on most modern Linux distributions, you may want to investigate use one of the distribution-specific options listed on the right.
Integration with regular dev: The files and compiler are sandboxed, apparently due to Apple Store requirements, so it's basically as self-contained as a web app. Pretty much like the FP Complete online IDE in that respect. It says here on the site: As required by the Mac App Store, Haskell for Mac.

There is a new ghc-dot-app project that is an alternative to Homebrew formula and Haskell Platform official installer. Here is the project's web page: Haskell for Mac OS X. Here is a discussion thread about it on Haskell Cafe: 'Self-contained GHC for Mac'. Here is a quote from the author's posting: How does it work? Download Eclipse IDE for Java EE Developers for Mac & read reviews. Create Java web applications easily. The integrated development environment Eclipse is a powerful tool for computer programming. JavaScript, Groovy, Erlang, Haskell, Julia, Lau, Lasso, Python, Ruby, and many more languages thanks to the multitude of plugins available.

The Haskell Platform

There are Mac OS X installers of the full Haskell Platform development environment. We recommend it:

Haskell for Mac (IDE)

Haskell for Mac is an easy-to-use integrated programming environment for Haskell on OS X. It is a one-click install of a complete Haskell system, including Haskell compiler, editor, many libraries, and a novel form of interactive Haskell playgrounds. Haskell playgrounds support exploration and experimentation with code. They are convenient to learn functional programming, prototype Haskell code, interactively visualize data, and to create interactive animations.

Features include the following:

Built-in Haskell editor with customisable themes, or you can use a separate text editor.
Interactive Haskell playgrounds evaluate your code as you type.
Easy to explore type information and to observe the behaviour of you program as you change it.
Playground results can be text or images produced by the Rasterific, Diagrams, and Chart packages.
Add code and multimedia files to a Haskell project with drag'n'drop.
Haskell binding to Apple's 2D animation and games framework SpriteKit.
Autosaving and automatic project versioning.

Haskell for Mac supports OS X Yosemite or above.

GHC

Important notes

To get the most out of your GHC environment, you should add '~/Library/Haskell/bin' to your PATH environment variable before the path where you have GHC installed. This will allow you to get and use cabal-updates, as well as other programs shipped with GHC like hsc2hs.

In your ~/.profile, add the line:

export PATH=$HOME/Library/Haskell/bin:$PATH

Mac OS X 10.9 (Mavericks), Mac OS X 10.8 (Mountain Lion) and Xcode 5

Both Mountain Lion and Mavericks support and now use XCode 5, which no longer provides GCC, only Clang.

The workaround that the Haskell Platform maintainers are supporting can be found here. That work around along with this one work with only the system provided compilers.

However, if you are still encountering usual bugs, the GCC based directions here may work out better.

Mac OS X 10.5 (Leopard)

To install GHC on Mac OS X 10.5 (Leopard), there are the following options:

install the Haskell Platform
install MacPort's ghc package

Mac OS X 10.6 (Snow Leopard) and 10.7 (Lion)

Install the Haskell Platform

To uninstall ghc call:sudo uninstall-hs

Xcode 4.1

GHC needs Xcode to be installed so it has access to the bintools, headers, and link libraries of the platform. The later two are provided by the SDK that comes as part of Xcode. GHC 7.0.2 is compiled against the 10.5 SDK. Xcode 4.1 no longer ships with it. ghci will work, but linking and some compiles with <ghc> will not. To make those work you need a copy of the 10.5 SDK. You can get this one several ways:

Before you install Xcode 4.1, if you have Xcode 3.2 installed, do one of the following:
- Move it aside (renaming /Developer to /Xcode3.2)
- Move just the sdk aside (moving /Developer/SDKs/MacOSX10.5.sdk to, say, /ExtraSDKs/MacOSX10.5.sdk)
- Move just the sdk aside, install Xcode 4.1, then move it back into the /Developer/SDKs directory.
If you don't have Xcode 3.2, then you can download it from the Apple Developer site, and install it in a location other than '/Developer'. If you have already installed Xcode 4.1 be sure that you customized the install and don't install the 'System Tools' or 'UNIX Development' packages.

Building via GHC:

Building via cabal:

Replace {loc} with wherever you put the SDK.

HUGS

install MacPort's hugs98 package.

Installing libraries with external C bindings

Haskell libraries are installed with the cabal command line tool.

Some libraries depend on external C libraries, which are best installed with MacPorts. However, you have to tell cabal to include the /opt/local/ directories when searching for external libraries. The following shell script does that by wrapping the cabal utility

Editors with Haskell support

Open Source

AquaMacs or EmacsForOSX, a graphical Emacs version
Eclipse with the EclipseFP plugin. See EclipseOn_Mac_OS_X
Emacs, is installed on every Mac
MacVim, a graphical Vim version
Textmate 2, open source incarnation of TextMate 1.
Vim, is installed on every Mac
Yi (written in Haskell itself!), is available through cabal-install

Commercial

TextMate:

Smultron:

and Sublime Text 2:

TextEdit is Mac's default text editor, a very basic editor that works fine for most uses, you must however be careful to put it into plain text mode using the Format menu.
