It's about 3 days that I can't do anything with my macbook air because the kernel_task is eating up the CPU. So I found this but the command csrutil disable/enable doesn't work on the terminal (El Capitan) and I found out that some models doesn't know this command but I couldn't find how else I can disable SIP (system integrity protection). So the questions is that how can I solve this problem with kernel task? enter image description here

  • SIP has nothing to do with what's allocating kernel_task. Can you show us a screen capture of your Activity Monitor? – Allan Sep 27 '18 at 15:40
  • @Allan I need to disable SIP for deleting those .kext files. I'll upload a screenshot now. – Nebula Sep 27 '18 at 15:47

    Don't delete kexts until you know what the issue is. – Allan Sep 27 '18 at 15:58
  • @Allan So what do you suggest here? – Nebula Sep 27 '18 at 16:07
  • First thing... see this post: apple.stackexchange.com/questions/179150/… – Allan Sep 27 '18 at 16:11

So after resetting SMC, rebooting safe mode and every other solutions that is suggested on different forums, changing the battery solved the problem!!! By the way, the battery was changed last year and it didnt need repair!!!
