mac启动wireshark时，提示没有权限抓包，报错内容如下：

“The capture session could not be initiated on interface ‘en0’ (You don’t have permission to capture on that device).
Please check to make sure you have sufficient permissions.
If you installed Wireshark using the package from wireshark.org, Try re-installing it and checking the box for the “Set capture permissions on startup” item.”

解决办法，打开终端，输入
sudo chmod 777 /dev/bpf*
