Cannot capture packets in monitor on Mac Mojave

asked 2018-10-05 17:19:33 +0000

I can capture the non monitor mode packets but can't capture in monitor mode. Could it be a bug around Mojave? Used my friend's older macbook and could do it

Just upgraded without issue. Monitor mode produced expected traffic flows on my WiFi networks.

Did you have to enable certain security settings? Wireless diagnostic is working correctly to capture packets but not wireshark.

No, wireshark worked fine, but it was previously installed prior to upgrade.

Ah that's odd, let me try asking around my friends who have Mojave to test. Thanks a lot!

Apple may have "improved" some of their AirPort drivers; see bug 15268, which has a Mojave capture with a bad Radiotap header. Perhaps Apple "improved" the Mojave driver for your machine's Wi-Fi adapter so that it doesn't support monitor mode.
