Q: Problem with Kernel Task - El Capitan
Since I have upgraded my MacBook Pro to the new OS, when it is unplugged, the Mac slow down and the Cpu usage is from 120 % to 300 % ( the process is Kernel Task).. What can I do?
Thanks a lot

I had this issue with a previous upgrade and this fix worked great. However, in El Cap this is a protected system file. In order to delete it you need to:
0. Reboot into recovery mode (Command + R on boot prior to startup chime), select Utilities/Terminal, csrutil disable <Enter> (repeat process, use csrutil enable after removing the file), reboot.
1. Go to About this mac under the apple in the upper left and click on More info
2. Click on system report
3. make a note of what it says after Model Identifier (MacBookPro8,2 is mine).
4. From the Root drive (not home folder): – System Library – Extensions – IOPlatformPluginFamily.kext (alt-click/View Contents) – Plugins – ACPI_SMC_PlatformPlugin.kext – View Contents – Resources -– find the name from step 3 and move it to a folder that you can find again if needed.
3. Restart and you’re done (other than enabling SIP).
I can use my Mac again!
