Aqui está um método um pouco mais simples usando o aplicativo createGcApp .
In addition to giving it a much more familiar interface, it also fixes some of the bugs in the previous script such as those preventing spaces in application names. The usage of the new version of the tool should be pretty straight forward. Start by downloading the .dmg, and opening the image. Inside, you should find a readme file, a script called createGcApp, and the source folder. Double-clicking the script will prompt you with questions about name, url, and icon for the application shortcut (make sure it's a square if you include an icon). The resulting file will then be saved to the /Applications folder. Thanks so much to Mait for sharing this much easier version.
