How to monitor CPU usage on your MAC

top -F -R -o cpu

 Type that in the Terminal and you’ll get a more efficient usage of top that uses less CPU itself, thanks to the flags. Here’s an explanation of the flags:

-F Do not calculate statistics on shared libraries, also known as frameworks.
-R Do not traverse and report the memory object map for each process.
-o cpu Order by CPU usage

By using top with those flags I have reduced top CPU usage to 1% and it’s also more appropriate for my needs. Try it out!
