I remember one of these processes making a brand new 2018 Macbook-Pro unusable.
It got so bad that I had to record the screen, showing my manager the absurd CPU usage, and input lag using VS-Code (type a letter see it appear 3 seconds later).
After a week of that, I basically had to send an email saying "either the security stuff you installed works, or I can work, but both will not work at the same time"
