kernel_task hogging my CPU, over 300%
Hi there, I was wondering if anyone can help me solve an issue with my mac.
I noticed that my kernel_task was really draining my CPU, hogging around 300%, barely leaving around 2% of RAM for the user. After doing a bit of research I found that kernel_task basically manages a load of extensions for your hardware and system programs.
Here's some pieces that i've learnt about the issues, as well as the steps that i've taken so far to try to resolve it.
- When I boot in safe mode the computer performs well, suggesting this could be a 3rd party extension issue
- Created a user profile, where the issue still occurs suggesting this is a 3rd party system extension
- Re-installed OSx to see if that would help it - nope
- Deleted the majority of my 3rd party apps, one by one to see if these were the issue. Still not fixed it as yet.
- I've not added any new RAM recently - I'm aware this can be a common cause of kernel_task issues
When I restart here's what the console is saying...

Any help that you can give me is greatly appreciated.
