Mac 系统禁用 ReportCrash 进程

晚上在 terminal 里敲代码,发现系统异常的卡顿。在 Activity Monitor 里发现 ReportCrash 进程占用了大量的 CPU

不断发送崩溃报告说明不断有进程在崩溃,先看一下系统日志

$ tail -F /var/log/system.log

我的天,每隔几秒 com.alipay.DispatcherService, com.apple.nowplayingtouchui 这两个妖孽就作怪一次。实在是太卡了,先不调查这两个可疑进程了,先把 ReportCrash 解决掉。

禁用 ReportCrash

直接干掉进程肯定不管用,从名字就知道这个进程会自动被触发,除非修改系统配置。

Google 了一下,发现很简单,在 terminal 里执行

launchctl unload -w /System/Library/LaunchAgents/com.apple.ReportCrash.plist
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.ReportCrash.Root.plist

再观察 Activity Monitor,会发现 ReportCrash 进程不再出现了。系统又恢复了如丝般顺滑的状态。

重新启用的方法(估计我这辈子都不会启动这货)

launchctl load -w /System/Library/LaunchAgents/com.apple.ReportCrash.plist
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.ReportCrash.Root.plist

com.alipay.DispatcherService 是马云爸爸下的什么蛋?

知乎上说是阿里用来检测支付插件是否有新版本而启用的后台进程,水木上有个老帖子说是阿里在偷偷收集用户隐私。当然,我觉得第二种说法更可信。毕竟,检测是否有新版本你启动的时候再检测不行么?

禁用方法

sudo launchctl unload /Library/LaunchDaemons/com.alipay.DispatcherService.plist 

再次查看 system.log 会发现 alipay 的相关日志不再出现了。说明禁用成功。

为了以防万一,把电脑上的所有阿里的软件都卸载了(虽然只有阿里旺旺一个)

com.apple.nowplayingtouchui 跟 touch bar 有关?

Google 到的禁用方法

launchctl unload -w /System/Library/LaunchAgents/com.apple.touchbar.agent.plist 

从命令来看,的确跟 touchbar 有关,然而我的老爷机上并没有 touch bar…

duang, SIP 阻止了我的操作

/System/Library/LaunchAgents/com.apple.touchbar.agent.plist: Operation not permitted while System Integrity Protection is engaged

我投降,我还是不敢禁用 SIP, 这个就这样吧,估计很快就被系统更新所修复

系统版本 10.12.3
