The arguments of packp3d don’t change on OSX, so there aren’t specific OSX aspects that you must consider when you use it on OSX. You can use it like if you were on Windows or Linux. Other useful commands (e.g. getting to the directory you want) aren’t Panda-specific: you can use the commands that you typically use on OSX (which you can easily map from the ones you already know on the other operative systems).
