unco record does not records any history with apple builtin binaries such as rm or vi.

But it still works with git which I installed with Homebrew.

my environment is macOS 10.14.6.

I think the reason is written at following page.

In older versions of macOS this could be used to inject a dylib into an Apple platform application with higher privileges. This would allow the injected dylib to also gain those additional privileges. Since the addition of SIP in macOS 10.12 this technique can no longer be used on Apple platform binaries.
