kernel task is using many resources on my mac

Question

kernel task is using many resources on my mac

Hi

I was working on my Mac but is coming very slow sometimes so I found the problem is the kernel task.

Lex I already use the Clean My Mac and since the first time I delete a lot of things I don't even remember how many. Should I format my drive?

About the iCleanMemory so the system will clear the RAM by it self or should I do something different or use another program?

So here is the report:

"CleanMyMac" is trash capable of corrupting a Mac to the point that erasing it completely is the only practicable means of recovery.

There is no way to reverse the effects of having used CleanMyMac2, and the developer's uninstallation instructions are ineffective. Only MacPaw, its developer, can know the reason for that, but I can think of two possibilities: either they are purposefully leaving components behind for reasons known only to them, or they simply don't know what they're doing. Neither one of those possibilities is particularly comforting for the user.

Reinstalling OS X alone will have no effect on either removing CleanMyMac or reversing the damage it is capable of inflicting upon a system.

Follow the applicable recovery procedure below:

If you have a backup that you created prior to using CleanMyMac, now is the time to use it. For Time Machine, boot OS X Recovery, and at the Mac OS X Utilities screen, choose Restore from Time Machine Backup. Choose a date preceding the installation of CleanMyMac.
If you do not have a backup that predates the use of CleanMyMac, create one now. To do that read Mac Basics: Time Machine backs up your Mac.
- The recovery procedure will require that you erase the Mac using OS X Recovery, and then create a new user whose contents will be empty. You will then be able to use Setup Assistant to migrate your essential documents including photos, music, work products and other essential files.
- When doing so, select only your previous User account and do not select "Applications", "Computer and Network Settings" or "Other files and folders". De-select those choices.
- Subsequent to using Setup Assistant, you will need to reinstall the essential software you may require, once again remembering to install software only from their original sources, and omitting all non-essential software.

To erase and install Mavericks read: OS X Mavericks: Erase and reinstall OS X

To migrate your essential documents read: OS X: How to migrate data from another Mac using Mavericks and follow the procedure under Time Machine or other disk migration.

Other problems may exist but those concerns will be rendered moot by erasing your system, which must be accomplished.

I found the problem is the kernel task.

How do you know that?

The kernel task is the one with the highest consumption or must demanding task running while I was having the problem.

thanks, John Galt

About the iclean memory should I remove that one as well? or not install it again? will the system clean the ram memory by it self?

I am using Parallels to be able to work on W7. and some times it is running out of memory. then the system is very slow and usually at that moment I run the Iclean memory app and helps it a lot.

You have all these kernel extensions installed, and any one of them will be an extension to the kernel_task
