Node-RED on Mac OS Sequoia - local network access issues

I had given up on getting Node-RED to run properly on my Mac after upgrading to Sequoia. The new Mac security protections that prevent local network access unless explicitly granted to applications is a real nightmare.

I recently asked perplexity.ai for help. Using its basic model, it gave me some suggestions that did not work. I switched to using its "research" model, though, and hit pay dirt.

I finally settled on this workaround and thought I would share it here in case it's of use to other Sequoia sufferers.

Follow this procedure to enable node red to access the local network:

Steps:

  1. Locate Node-RED’s installation path:
    which node-red # Typically /usr/local/bin/node-red
  2. Create a wrapper app bundle:
sudo su
mkdir -p /Applications/Node-RED.app/Contents/MacOS
cat > /Applications/Node-RED.app/Contents/Info.plist <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>CFBundleExecutable</key>
    <string>node-red</string>
    <key>CFBundleIdentifier</key>
    <string>org.node-red</string>
    <key>CFBundleName</key>
    <string>Node-RED</string>
</dict>
</plist>
EOF

ln -s $(which node-red) /Applications/Node-RED.app/Contents/MacOS/ 
exit

open /Applications/Node-RED.app

Now find the settings pop-up and authorise local network access for “node”.
This gives Node-RED a stable bundle ID, allowing macOS to track its permissions.

You can terminate Node-RED and then use your normal method of starting it. It should now be able to freely access the local network.

I hope this is helpful to someone.

Hi, thanks for sharing that, I'm sure it will be useful to others. I've taken the liberty of moving to the FAQ's section for easier future reference. :slight_smile:

@ozdw I’m curious, how are you trying to use local network access?
