1. Start the Terminal application, and use the cd command to set your path as needed.
2. Enter the following at the command line:
chmod g+rx <filepath>or
chmod g+wrx <filepath>The g+rx is necessary because plug-ins and system scripts must have the group read and executable bits enabled. Use the g+wrx form to permit write permission as well. Some plug-ins or scripts that use preferences or folders of additional files may require write permission to those files or folders.
