This script allows to export icons created in Adobe Illustrator directly to a multiresolution .icns file. It has been tested for CS6.
You can just clone/unpack the icns-export.jsx file anywhere to your computer and then run it via File > Scripts > Other Script.... If you want the script to occur in the Scripts menu permanently, copy the script file to
- Mac OS: /Applications/Adobe lllustrator CS 6/Presets/[language]/Scripts/
- Windows: C:\Program Files\Adobe\Adobe lllustratorCS6\Presets[language]\Scripts\
