前言⌗

偶然在系统设置的 Login Items 管理中看到一个没有 Icon 的后台服务，如下图所示：

上图中的 TNT 项目就是一个看着比较奇怪的后台服务项，经过一番搜索才知道这是一个组织。

清理⌗

macOS 的服务项配置文件常见目录有如下几个：

系统等录项⌗

• /Library/LaunchAgents
• ~/Library/LaunchAgents
• /System/Library/LaunchAgents

后台服务项⌗

• /Library/LaunchDaemons: 用户的后台服务项
• /System/Library/LaunchDaemons: 系统的后台服务项

经过一番审查，并没有找到 TNT 相关的 plist 配置文件，然后看到网上有人提到 SMAppService，还有就是 sfltool。

sudo sfltool dumpbtm

通过这个命令可以输出系统的等录项和后台服务项相关注册信息，然后找到对应的 plist 文件再删除即可！

I hope this is helpful, Happy hacking…
