top equivalent to show I/O per process (per second) on mac/osx

Question

Is there a top-like (visual) tool which can show per process disk I/O (kb/sec)?

The question was already asked at Monitor disk activity, á la top, or nettop (per process) on a Mac? and What's causing all the disk activity on OS X?, but iotop doesn't work in El Capitan.

Output of IOTOP on OSX El Capitan:

$sudo iotop

dtrace: invalid probe specifier
 /*
  * Command line arguments
  */
 inline int OPT_def     = 1;
 inline int OPT_proj    = 0;
 inline int OPT_zone    = 0;
 inline int OPT_clear   = 1;
 inline int OPT_bytes   = 1;
 inline int OPT_elapsed = 0;
 inline int OPT_dtime   = 0;
 inline int OPT_percent = 0;
 inline int OPT_device  = 0;
 inline int OPT_mount   = 0;
 inline int OPT_file    = 0;
 inline int OPT_top     = 0;
 inline int INTERVAL    = 5;
 inline int COUNTER     = -1;
 inline int FILTER      = 0;
 inline int TOP         = 0;
 inline string DEVICE   = ".";
 inline string FILENAME = ".";
 inline string MOUNT    = ".";
 inline string CLEAR    = "
";

You have to partially disable SIP to allows dtrace debug, so as to make iotop work on 10.11+:

csrutil status show: System Integrity Protection status: enabled (Custom Configuration).

Configuration: Apple Internal: disabled Kext Signing: disabled Filesystem Protections: enabled Debugging Restrictions: enabled DTrace Restrictions: enabled NVRAM Protections: enabled BaseSystem Verification: enabled

I've personally disabled it completely, but you probably can limit yourself to DTrace restriction if you'd better play it safe.
