 ## macOS
 
-To simply use a snapshot of Dynare, you have two choices. On MATLAB, you can
-use the [snapshot build](https://www.dynare.org/snapshot/macos/) provided by
-Dynare. On Octave, you can simply install [Homebrew](https://brew.sh/) and run
-```brew install dynare --HEAD``` (See the Install Dynare (unstable) section of
-[this webpage](https://archives.dynare.org/DynareWiki/InstallOnMacOSX) for more
-details).

-If you do not wish to use the snapshots provided by Dynare or Homebrew, follow
-the directions below to build Dynare on your local machine.

 Preparatory work:
 
 - Install the Xcode Command Line Tools:
     - Open Terminal.app and type `xcode-select --install`
 - Install [Homebrew](https://brew.sh/) by following the instructions on their website
+- Install [MacTeX](http://www.tug.org/mactex/index.html). Alternatively, if you
+  don’t want to install MacTeX, you should pass the `--disable-doc` flag to the
+  `configure` command below.
 
 The following commands will install the programs that Dynare needs to

-- **(Optional)** To compile Dynare mex files for use on Octave:
-    - `brew install octave`
-- **(Optional)** To compile Dynare documentation
-     - Install the latest version of [MacTeX](http://www.tug.org/mactex/), deselecting the option to install Ghostscript
-     - `brew install doxygen latex2html`

+- Compile and install SLICOT, needed for the `kalman_steady_state` MEX file
