This guide covers Therion 5.3.16 installation on OS X (10.9+) using Homebrew package manager.

We will need:

  • Command Line Tools
  • MacTeX distribution -
  • Homebrew package manager - - In comparison to other package managers like Fink or MacPorts Homebrew works hard to avoid package duplication - Homebrew compiles its packages against libraries built into OS X.
  • Terminal - standard part of OS X installation

Download and install MacTeX full package from


Launch Terminal and type the following command to install Command Line Tools:

xcode-select --install

Click “Install” to download and install Xcode Command Line Tools.

Install Homebrew - see instructions on

Then run:

brew update
brew doctor

Follow (if any) instructions in results of “doctor” command.

brew tap homebrew/science
brew install

Now it is good time for cofee/tee/beer or whatever you prefer as it definitely takes a few minutes to download/compile/install all dependencies.

Done? Still awake? Lets try to launch Therion GUI alias XTherion:


Loch should be available as well in Applications folder.

In case you would like to switch XTherion UI to different language than English please find /usr/local/etc/xtherion.ini configuration file and uncomment and change following line:

#::msgcat::mclocale en

to (for Czech):

::msgcat::mclocale cz

You can find list of available translations in the Therion Book.

Following commands will keep you updated in the future:

brew update
brew upgrade
