Plus points for using strace. It's one of those debugging tools everyone know about for emergencies that can't be solved at a higher level, and a great convenience of using Linux. The Windows ETW system is much harder to use, and I'm not sure if it's even possible at all under OSX security.

macOS’s Solaris-inspired dtrace is actually nicer, especially the UI.

Is there a guide for how to use this, including the UI, with SIP on?

Instruments is implemented under-the-hood with dtrace, that could be what they are referring to.

Yes. Most things run well with Instruments attached. I’ve only used the dtrace cli a few times.
