perf, strace, and pstack can be replaced with dtrace on MacOS.

You can have a case-sensitive position. (Separate from root so it doesn't break some apps)

Do you need to add dtrace to the key chain each time it's updated or do they just not update it like most of their command line software?

What do you mean "add dtrace to the key chain"? I've never done anything related to keychain while using dtrace.

gdb needs to be added to the keychain as a signed program in order to attach to programs. But brew is a rolling release so I might need to add this frequently. It's painful.

DTrace is built-in software.

I took some time to try dtrace out. Sadly it's broken unless one turns off SIP:

Only when tracing the operating system, not your program. But yes, that is still a shame. You don't need to turn off SIP globally, you can just enable DTrace while keeping the rest of SIP on.
