Please tell me why I can't capture.
I checked both Monitor Mode and Promiscuous.
By the way,I could not get capturing even the following command.
sudo dumpcap -I -i en0
If tcpdump can't capture it, that's a macOS issue, not a Wireshark issue. Please report a bug to Apple.
Thank you for your answer! After all it is so…
However, when I inquired Apple, operations on the terminal and other applications were not subject to inquiry.
Thank you for your comment!
When I run sudo tcpdump -i en0 -I -vv,I get the following results.
tcpdump: listening on en0, link-type IEEE802_11_RADIO (802.11 plus radiotap header), capture size 262144 bytes
--after five minutes--
^C

What do you mean by "can't capture"? Do you mean that you get an error using dumpcap, or that you don't get an error but no packets are captured, or what?
And, again, what happens with
sudo tcpdump -I -i en0?Thank you for your comment!
The latter is correct,I don't get an error but no packets are captured.
When I run
sudo tcpdump -I -i en0 -vv, The following is displayed on the terminal.tcpdump: listening on en0, link-type IEEE802_11_RADIO (802.11 plus radiotap header), capture size 262144 bytesafter 10 minutes I runed
