Step 3.1 for bash: When copy pasting from the web page, the ' in the alias command confused my Mac and it could not find Python. The same command sans ' worked fine.
Step 5: Copy pasting the ln command from Chrome to the command prompt resulted in "file or directory app" not found. Eventually got frustrated and typed the command by hand which worked. Do not see any non printing characters or other strangeness in the web page itself which would have caused the error. Step 5: The web server starts just fine and I see requests coming in, but always getting page not found. Looked in the run_webservices.py file and noted most of the paths were relative to the ocw-ui directory rather than the backend directory from which the wiki says to start the services. Also noted this file refers to a front end/bower_components directory which doesn't seem to exist on my clone. Any help with this last step much appreciated. Sent from my iPhone
