Set up Seam Bridge to reboot on restarts

Use launchd to keep the Seam Bridge running on macOS. A LaunchAgent restarts the app if it crashes and starts it whenever the user logs in.

Create and Launch the LaunchAgent file

1. Open Terminal.

2. Create a plist file in your user LaunchAgents directory:

   mkdir -p ~/Library/LaunchAgents
   nano ~/Library/LaunchAgents/com.seambridge.keepalive.plist
   

3. Paste this template:

   <?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>Label</key>
       <string>com.myapp.keepalive</string>
   
       <key>ProgramArguments</key>
       <array>
         <string>/path/to/app/SeamBridge.app/Contents/MacOS/SeamBridge</string>
       </array>
   
       <key>KeepAlive</key>
       <true/>
   
       <key>RunAtLoad</key>
       <true/>
     </dict>
   </plist>
   
   

4. Replace /path/to/app with the actual path to your binary/script. Keep the /Contents/MacOS/SeamBridge path at the end.

5. To save your changes in Nano:

   • Ctrl X to Exit.
   • Y to save changes.
   • Confirm the file name and click Enter.

6. Within terminal, paste the following command to launch the launch agent:

   launchctl load ~/Library/LaunchAgents/com.seambridge.keepalive.plist

2. launchd should restart it automatically.
3. Restart your Mac and confirm the app launches on login.
