<?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.example.app</string> <key>Program</key> <string>/Users/Me/Scripts/cleanup.sh</string> <key>RunAtLoad</key> <true/> </dict> </plist>
