此博客是我在远景论坛上黑苹果板块于2013年发表的这篇帖子修改得来,所以主要面向于黑果无法监测CPU变频的情况下的解决办法

UserEventAgent

在测试 CPU 变频的时候,因为 UserEventAgent 进程疯狂的占用 CPU 使用率,每次开机后十分钟之内都一直 100%

  1. 让 CPU 频率无法变动,或者变动非常小
  2. 第二就是因为 CPU 频率一直最大,发热量很大。

不管怎么样,有问题就试着解决,最后找到了解决方法[1]

原文

I have fixed it! Here is what I did:

I saw this output of a list of files attached to this process, so I thought, what if I delete one?

/System/Library/UserEventPlugins/AppleHIDMouseAgent.plugin/Contents/MacOS/AppleH IDMouseAgent

This seemed to be the driver for an non-apple mouse, a HID (Human Interface Device) USB driver

This is what the driver contains, opening it in Coda:
System/Library/Frameworks/IOKit.framework (Wasn't that for reading CPU temp?)

HIDHotPlugHandler (Plug USB mouse in, and turn CPU up?)

HIDUnplugHandler (Unplugging USB mouse, and put CPU down?)

com.apple.AppleHIDMouseAgent (That's the drivers name)

I don't know this all, and if it was needed. SO I just deleted the AppleH IDMouseAgent.plugin, and everything is working fine now! Even the apple magic mouse is still working.

(ACTUALLY I DON'T DELETED THE PLUGIN, I JUST MOVED IT TO MY DOCUMENTS FOLDER, JUST IN CASE...)

I hope this helps, and could this have any concequences? Apple does NOT include plugins that can just be deleted, I guess?

我拙译一下重点

我看了这个进程所连接的文件列表,所以就尝试的删除 /System/Library/UserEventPlugins/AppleHIDMouseAgent.plugin/Contents/MacOS/AppleH IDMouseAgent

这个看起来是非苹果鼠标的驱动,HID(human interface device人性化接口设备) USB驱动

这是驱动的详情,用Coda打开 System/Library/Frameworks/IOKit.framework (这是为了读取CPU临时缓存么?)

HIDHotPlugHandler (USB鼠标一插就让CPU频率猛增?)

HIDUnplugHandler (不插USB鼠标就会让CPU频率降下来?)

com.apple.AppleHIDMouseAgent (这个是驱动的名字)

我不知道他们是否都必须,所以我只是删除了 AppleHIDMouseAgent.plugin,但是所有的都能够正常工作!甚至 Apple Magic Mouse 也能正常工作

(我希望这个有效,但是这个有什么后果么?我猜除了这个插件之外都不可以被删除)

解决办法

System/Library/UserEventPlugins/AppleHIDMouseAgent.plugin/Contents/MacOS/AppleHIDMouseAgent 删除,重启即可
