Jupyter Notebook doesn’t Automatically Open a Browser on OS X

This issue appears to have showed up on Sierra. Here’s a simple fix:

  1. Edit your bash profile (emacs ~/.bash_profile)
  2. Add export BROWSER=open
  3. Close your shell or source it (source ~/.bash_profile)

Things should get back to normal now.
