  <p>I found this question:
  <a href="https://stackoverflow.com/questions/19688841/add-python-to-os-x-firewall-options">Add Python to OS X Firewall Options?</a></p>
  
  <p>I followed the accepted answer to do but finally when I run <code>codesign -s "My Signing Identity" -f $(which python)</code>, it said:</p>
  
  <pre><code>/usr/bin/python: replacing existing signature
  error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate: can't create output file: /usr/bin/python.cstemp (Operation not permitted)
  /usr/bin/python: the codesign_allocate helper tool cannot be found or used
  </code></pre>
  
  <p>How to do next?</p>
