Ever since I tested software on macOS, I deeply missed my beloved strace that I use when programs are missbehaving. macOS has dtruss but it's getting locked down and more unusable with every machine. My approach uses the signed lldb binary on the system and re-implements the output you are know from the wonderful strace tool. I just created the tool yesterday evening, so it may have a few bugs, but I already got quiet a few integration tests and I am happy so far with it.
