I'm new to mac so i don't even know how to properly ask.

Could someone help me?

Answer 1

According to User: gmale's answer on ask.wireshark.org, he solved his problem in this way and I'm sure that it could solve yours as well. It says:

1- Open Terminal

To see your exact user name (for me that was AliGht)

2- Type 'whoami'

3- execute the following commands:

cd /dev sudo chown AliGht:admin bp* 

and enter your computer password:

4- now type this command:

ls -la | grep bp 

The last command will display a list of files such as:

5- Make sure all of them have your user name and admin as the user/group. For some reason, the last one didn't get assigned properly so I had to run the command:

sudo chown AliGht:admin bpf4 

so the last command fixed my problem as you see in the last image:

Done!

If your WireShark is open then close it and open it again.

If you want to open WireShark always as administrator then take a look to another post which I created a shortcut for it via Applescript, and this is the only way which you can open the WireShark always as administrator even when you turn off/on your mac.
