应用使用 macOS 的 nettop 命令获取各进程的上传和下载字节数。通过持续执行 nettop 命令并计算差值，可以得出每个进程的网速详情。
The app uses macOS's nettop command to get the uploaded and downloaded bytes of each process. By continuously executing the nettop command and calculating the difference, we can determine the network speed details for each process.
使用的 nettop 命令：
nettop -x -t wifi -t wired -J time,bytes_in,bytes_out -P -l 1本项目采用 MIT License 开源协议。这意味着你可以自由地：
