Mac Bug之二 UserEventAgent占用内存20G、CPU 100%

现象：开机或登录，UserEventAgent占用CPU 100%，内存占用每秒疯狂增长，曾经达到过20G被Force Quit

可重现：100%重现

解决方法：开机执行如下shell脚本，并输入密码

bugpid=`ps -ef |grep UserEventAgent |grep System |awk '{print $2}'`echo 'UserEventAgent (System) pid was '$bugpidsleep 2sudo kill -9 $bugpidsleep 1bugpid=`ps -ef |grep UserEventAgent |grep System |awk '{print $2}'`echo 'UserEventAgent (System) pid is '$bugpid

以下是相同案例，但通过禁止某些系统启动项 来解决的
