How can we get the BSSID value for a wifi network without sudo

ah, darn it...wrong parameters. That one is on me - that's the MAC of your computer's wifi card, not the access point it connects to...try this:

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport en1 --getinfo | grep BSSID | awk -F ': ' '{print $2}'

This command used to work earlier but its not giving the required data now.

ioreg -l -n AWDLPeerManager | perl -lne 'print $1 if $_ =~ /IO80211BSSID.*<(.*)>/;' | fold -w2 | paste -sd: -

Any idea what alternative command we could use to get network bssid value?

I am unclear the circumstances here...

You can see the BSSID from the drop down menu Option click the WIFI icon

Just open your Terminal application and use command man networksetup and use the to see! If your other hand is available the control button+click on Airport icon in Finder menu.

Well, hopefully you do - I had a few minutes to play around on my Mac Mini running Sonoma over the weekend...on the newest macOS, wdutil requires sudo for the info command (which it did not used to), and even when run under sudo, there are pieces of info including SSID and BSSID that are redacted - literally, the info is replaced with the string "redacted".

Why Apple wants certain Wifi info that is literally broadcast over the air only accessible programmatically from NetworkKit and presumably using entitlements...no idea. But it seems that's the choice they have made.

Good luck with the dev forum.

networksetup -getmacaddress <hardwareport>, replacing <hardwareport> with the interface designator (en1, etc) of the Wifi interface.

The output will be of the form: "Ethernet Address: aa:bb:cc:dd:ee:ff (Device: en1)". Play around with awk to get the output you need.

You’ll want to want to plan for the sudo requirement, even if you can get this to work now.

sudo wdutil info | grep "BSSID"

I don’t have macOS (specifically 14.5 Sonoma, or later) handy to check whether this still works, but this might still work:

networksetup -getairportnetwork en0 | awk -F ': ' '{print $2}'

This change is presumably happening because too many developers were using BSSID for tracking purposes or other shenanigans.

I’ve probably got some semi-recent Swift code around that pokes at this stuff too, but that code will likely require sudo or entitlements past 14.5. If that’s interesting, let me know and I’ll dig it up, dust it off, test it on macOS 13 latest (again, no macOS 14 is handy for testing), and post it here.

Sounds like you need to ask this question in the Apple Developer Community, not here.

It looks like wdutil ought to have replaced the airport tool - but I've never managed to get anything out of

wdutil info

even running sudo.

The fact that there are apps that provide Wifi info and control means there is obviously a way to do it - and if you can get the info without elevated permissions or entitlements, then the developers are the ones to ask.

I just ran it without sudo and it produced a MAC address.

Perhaps try giving Terminal Full Disk Access (but I didn't have to do that, either).
