iOS - Doesn't scan for wifis when not already connected to a wifi

[daggala]

macOs High Sierra - Version 10.13.6.

I have to be already connected to a wifi so that it gives me a list of wifis. If not, I only get empty list.

Then there's another problem for which might create another issue. I'm working on linux and mac parallel so when I scan for wifis on the mac I get sometimes the same wifi 4 times whereas on linux I don't get any duplicates.

Hi, Is it possible to have nmcli and airport standard output ?
