Then again install pcap-ct, and finally add in the libpcap\_platform\__init__py the missing is_osx = False. (Is in the meanwhile fixed in the github repository.)
Finally, we need to patch the Pcap-ct, because the python script needs a non-blocking version. This is discussed in https://github.com/karpierz/pcap-ct/issues/9
Now, in the IDLE shall 3.10.6, the import works:
```
import pcap
sniffer = pcap.pcap(name=None, promisc=True, immediate=True, timeout_ms=50)
addr = lambda pkt, offset: '.'.join(str(pkt[i]) for i in range(offset, offset + 4))
for ts, pkt in sniffer:
print('%d\tSRC %-16s\tDST %-16s' % (ts, addr(pkt, sniffer.dloff + 12), addr(pkt, sniffer.dloff + 16)))
```
