Question: Noobie here.

Should I open Mac terminal and cd to /Applications/Blender/ which is where my Blender app is? Doesn't seem to work for me trying to run script from Text screen in Blender. I guess there is no way to see output within Blender itself?

Answer: 
The only way to see the Blender console and thus the script output is to launch Blender from a terminal using the full path to the executable: `"/Applications/Blender/blender.app/Contents/MacOS/blender"`

All script output will appear in the terminal only.

Following @DickMeehan's comment and since I hate to install yet another App, here is the AppleScript to automatically start a Blender with its Terminal window.

Note: tested on `MacOS High Sierra 10.13.3` only:

```
    set blenderAppPath to "/Applications/Blender/blender.app/Contents/MacOS/blender"

    (* This command will open a Terminal app that should be closed with CMD-Q otherwise
   it will persist after Blender and the terminal window are closed with CMD-W *)

    set openCmd to "open -n -W -a /Applications/Utilities/Terminal.app/Contents/MacOS/Terminal --args "

    do shell script openCmd & blenderAppPath

```

Refer to the following to make an actual clickable App using the Automator. This app can then be simply dragged to the launch bar for convenience.

Without creating a new application with Applescript and all, you can just create a shell script with the '.command' extension. The extension makes it clickable, which opens a console and executes the file.

1. Open a terminal
2. `cd /Applications`
3. `nano Blender.command`

paste this and save the file

```
#!/bin/sh

cd `dirname $0`;
./Blender.app/Contents/MacOS/Blender

```

4. `chmod u+x Blender.command`

Now click on the 'Blender.command' icon next to your Blender application.
