Some system processes like systemsoundservd, logd, diagnosticd, etc. recently use a lots of cpu on my macbook pro. How can I limit them to some degree because most of them are not too relevant to me?
Note: I have already checked out Can I manually limit the %CPU used by a process? but it does not seem to work as expected.
