How to limit speed on Mac OS with pf + dn?

Question

macOS

Hello. I read a bunch of manuals, man to pf and dn, but nothing happens. I create a pipe, I create a rule in dn, but the speed is not limited. Not on old not on new connections.
Can anyone help?

And there everything is quite simple, like. Here is one example.

Set the delay in ms:
sudo dnctl pipe 10 config delay 500

Check for loopback:
ping -c3 127.0.0.1

PING 127.0.0.1 (127.0.0.1): 56 data bytes
Request timeout for icmp_seq 0
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=1001.083 ms
