I am struggling to find out what process is eating away my Mac performance, and disk i/o is the culprit. Activity Monitor frequently shows megabytes of read/write, but unfortunately, it does not show the per process value (only total written by given process, which is useless). Is there a way to find out? iotop does not seem to work, because I am on Sierra, and SIP is enabled.

Thank You, Zsolt


iStat Menus shows, among many many other things, disk activity by process. It is not free, but you can do a 14 day trial.
