Performance profiling on macOS (arm64 or x86)

OCaml gained support for perf profiling on Linux. Is there something equivalent for profiling on macOS, either Intel or ARM?

Recently I realized symbols seem to be showing up again in the xcode profiling tools.

Try something along these lines:

xcrun xctrace record --template='Time Profiler' --launch -- /path/to/your/exec

macOS has a sampling profiler /usr/bin/sample but I can’t get something useful out of it (tried OCaml 4.12.0 and OCaml 4.08) but maybe my program is not running long enough.
