Mac 系统休眠之后，再唤醒，还是卡顿的无法使用。
看了活动监视器，launchd 在重启之后产生了大量的磁盘 IO。
这非常不正常。
猜测 launchd 是在写入系统日志，所以造成了大量的磁盘写入。
$ tail -F /var/log/system.log

果然，日志在不断产生。
com.alipay.DispatcherService 是什么
我确信已经删除了所有 Mac 上的阿里系应用，怎么还在不断报错。。。
执行
sudo launchctl unload /Library/LaunchDaemons/com.alipay.DispatcherService.plist
再次查看 system.log 已经没有新的错误日志产生了。
之前在 处理 ReportCrash 问题 时，禁用过该进程，看来并没有根除。
以防万一，删除支付宝的残留
sudo rm -rf /Library/LaunchDaemons/com.alipay.DispatcherService.plist
