About the Alan distribution for Mac OSX: This distribution does not contain anything apart from the executable compiler and interpreter for Intel-based machines. As of now there are only command line versions available of them. Gargoyle (https://code.google.com/p/garglk/downloads/list) is a multi- interpreter GUI including an older alan interpreter. You can update it using the slotin replacement available from the Alan Home Pages. You can use any text editor to write you Alan game. A recommended GUI to create new games is the AlanIDE, available from http://www.alanif.se. There you also can find documentation, an extensive standard library as well as some sample code. The port was made on a MacOSX 10.9 Intel Macbook Pro by Thomas Nilsson (thomas@alanif.se).
