I found this interesting bit at G'MIC Flickr, for using custom filters with Mac:

How to add custom filters?
As a reference, I explain shortly here how to install custom-made new filters which appear now and then in this Flickr group and are not included with the standard G'MIC distribution.
-Download the filter: it will appear as a text.
-Copy the text into a plain text file and save it with the name ".gmic" in the User Home folder. It will be loaded the next time you use G'MIC.
The problem is that on Mac OSX the files with a name beginning with a dot are usually used by the System and always kept invisible, and the user is normally prevented from editing them and from creating them manually (programs can create them automatically, anyway).
If you try to save a file with a name beginning with a dot, an alert appears suggesting you not to do so ("Filenames beginning with a dot are used by the System, choose another name").
Anyway, on Mac OSX, these files can be produced, saved, opened and edited with programs like BBEdit Lite (a text editor for programmers, from
http://www.barebones.com/) and with other specialized text editors (BBEdit has also a special menu item "Open Hidden…" to edit them) and with any text utility which can find and open hidden "invisible" files (those with the names beginning with a dot).
The .gmic file (as well as the ".gmic_def" and the ".gmic_faves" files, created automatically by G'MIC), once created, is really in the User Home directory (folder) and this method works well.
You can also use (for example) Tex-Edit Plus (from
http://www.tex-edit.com/ ) instead of BBEdit to create, open, edit and save the "invisible" files (in Tex-Edit Plus, if you press the "option" key before you choose "Open" it becomes "Open as text…" and you can see and open also the invisible files).
