To see the CPU and memory usage of processes in htop on Mac OS X you need to change the user rights as described in "htop isn't returning CPU or memory usage!?".

htop running with root rights is able to stop and kill any process. I don't recommended to use htop with superuser rights without any password confirmation.

What is the best alternative with as less rights as possible?


For better system security glances i.e. is a better choice for just monitoring the system.

  • Cause it does not need root privileges, it is just saver to work without admin rights. – tasmo Aug 6 '16 at 11:57
