解决那些在 macOS 上霸占 CPU 使用率的进程 - UserEventAgent
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%
- 让 CPU 频率无法变动，或者变动非常小
- 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
把 System/Library/UserEventPlugins/AppleHIDMouseAgent.plugin/Contents/MacOS/AppleHIDMouseAgent 删除，重启即可
