Hi, tracexec only supports linux for now since it uses some ptrace features specific to the linux platform.

[kxxt]

After searching for ptrace on MacOS and reading the compiler error you get(which indicates that seccomp-bpf isn't available on MacOS either), I think it's very hard to get tracexec working on MacOS with reasonable performance. So I am going to close this issue as won't fix.

A much more comprehensive tool, strace, doesn't support MacOS either: Homebrew/homebrew-core#159527
