You need to use sudo. I have SIP enabled and use DTrace regularly. Trust me, it works. (As long as you use it properly, i.e. not like an alias for strace the way you tried here.)

Sigh.

  » sudo dtrace echo hi
  dtrace: system integrity protection is on, some features will not be available

  dtrace: no probes specified
  (last command returned 1.)
  » sudo dtruss echo hi
  dtrace: system integrity protection is on, some features will not be available

  dtrace: failed to execute echo: Operation not permitted
  (last command returned 1.)

There's a host of problems that come with that, though: how do you then execute the tracee? If your problem is nice & simple and works under root, that's great I suppose, but it always seems like some access to $HOME destroys that possibility for me.

Then there's that, even ignoring all that … I've still yet to figure out a minimal example?

Give me a barebones minimal example. Every article I hit on this tool is right into space shuttle levels of complexity. That's what makes strace the winner.

… "you're holding it wrong."
