Mac 系统上 launchd 进程产生大量磁盘 IO

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。

Mac 系统上 launchd 进程产生大量磁盘 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
Aug  4 18:26:21 Sun-Zhongweis-MacBook-Pro com.apple.xpc.launchd[1] (com.alipay.DispatcherService[1074]): Service exited due to signal: Illegal instruction: 4 sent by exc handler[0]

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
