[暂未解决]mac中系统进程kernel_task太耗内存

[问题]

mac使用期间,发现有些程序运行不流畅,有点点卡顿时,

去看 活动监视器 中 内存占用中,

有个kernel_task

占用了1G多的内存:

想要搞清楚:

这个kernel_task是个什么东西

占用了1.2G内存,是否属于正常现象?

注:此处CPU占用率倒是正常的。

不过也去看了,CPU占用率,在5%前后:

[解决过程]

1.搜:

mac kernel_task

参考:

kernel_task high memory usage | Apple Support Communities

去看看:

/System/Library/Extensions

里面有几十个.kext

所以肯定不可能去删除这么多。。。

kernel_task 到底是个什么神奇的东东啊???,Mac OS X 讨论区-MacX.cn –

“直接升级会有这个进程,如果抹除重新安装就没有这个问题了。

抹盘安装也会有这个进程。新机器没有plist可以删,而且删除的话可能有其他风险。

去看看我的这里是否有:battery time remaining 2

此处没有这个程序:

其他也没看到异常。

去进入:

Macintosh HD-》系统-》资源库-》Extensions

搜索:

IOP

点击 Extensions

2.参考:

MAC解決kernel_task讓cpu突然飆高100%,150%的有效方式 | 計算0123456789

去看看:

mac系统版本:

OS X 10.11 EI Caption

对应的:

型号标识符:    MacBookPro12,1

继续打开:

/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns

然后去:

[已解决]mac的finer中如何复制只读文件的文件名

拷贝到该文件名:

/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext

然后进入:

/System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents

结果里面没有找到:

MacBookPro12,1

去看了看kextstat,输出一大堆:

也看不懂。。。

搜:

mac kernel_task too much memory

参考:

kernel_task high memory usage | Apple Support Communities

突然想起来了:

我最近是从OS X Yosemite升级到OS X EI Caption

但是好像是没有重启过Mac

所以:

去重启Mac试试,或许能解决问题?

CPU和内存占用还是比较多的。

参考:

What is kernel_task and why is it taking up so much memory? | MacRumors Forums

说是:

如果系统运行了:

adobe flash

Safari的ClickToFlash,Firefox的FlashBlock 或FlashBlock Youtube的HTML5视频播放器

则都可能会导致:

kernel_task的CPU和内存占用率较高

[总结]

目前,还是没有找到根本原因。

经过重启后,kernel_task的CPU和内存的占用率,稍微低了点,但也还是很高,内存占用1G左右。

据说,可能是和flash有关的东西(adobe flash,Safari的ClickToFlash,Firefox的FlashBlock 或FlashBlock Youtube的HTML5视频播放器)导致了kernel_task的资源消耗大的。但是未经证实。

暂时,就这么着吧,还是不清楚根本原因。
