[MacOS] 新增啟動文檔 /etc/rc.local 至MacOS

• 創建plist文件
  
  #sudo vim /Library/LaunchDaemons/local.localhost.startup.plist

• 複製以下XML至文件
  
  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
  <plist version="1.0">
      <dict>
          <key>Label</key>
          <string>local.localhost.startup</string>
          <key>Disabled</key>
          <false/>
          <key>RunAtLoad</key>
          <true/>
          <key>KeepAlive</key>
          <false/>
          <key>LaunchOnlyOnce</key>
          <true/>
          <key>ProgramArguments</key>
          <array>
              <string>/etc/rc.local</string>
          </array>
      </dict>
  </plist>

• 啟用服務
  
  #sudo launchctl load -w ./local.localhost.startup.plist

• 創建rc.local
  
  #sudo vim /etc/rc.local
  #sudo chmod 777 /etc/rc.local

[1]  Mac下用Launchd实现使用rc.local执行开机启动命令
