According to Activity Monitor my system is always running too high for CPU load. It’s always in the red in the CPU load graph and nothing I do corrects this.

I’ve tried resetting NVRAM, SMC and rebooting, so is this a problem with some sort of extension?

How do I fix this?!?!

Your confusion is the result of a bad UX design decision on behalf of Apple.

Basically, the red colour in the CPU Load graph within Activity Monitor signifies the level of CPU usage by the System. The blue colour signifies the level of usage by User processes.

In other words, red isn’t being used to signify danger, or to try to alert users to a problem, it’s simply the colour chosen to signify system usage. So, if the system is using 1% or 99% of the CPU, it will always be displayed in red.
