Silly question but doesn’t macos ship with dtrace? So why not use dtruss?

  You need to disable SIP to use DTrace
  • Citizen8396 11mo ago
    Not entirely. You can selectively remove protections: csrutil enable --without dtrace
    • saagarjha 11mo ago
      That’s disabling SIP

  dtruss requires disabling SIP. This seems like a better option for basic "what just happened?" debugging.

  Barely supported by Apple these days - in addition to needing to disable SIP which is a pain, it was broken causing system freezes for several major macOS releases.

  Another silly question, did everyone forgot about instruments?
  • youngtaff 11mo ago
    Isn't Instruments built on dtrace?
  • viraptor 11mo ago
    Does instruments allow you to track file reads/writes and other syscalls/mach stuff? Their docs are quite bad at describing the capabilities, so I'm not really sure. From what I can see it's a profiler rather than a tracing tool.
