I would like to get channels from wi-fi around me on Mac High Sierra. I tried Wireless Diagnostics but I can see only this window
I was going through the steps and then I got only some files and folders saved to my mac.
Can somebody please help? Thank you.
You can run this command:
/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -s
