Airsweep
See the Wi-Fi around you
Airsweep is a Wi-Fi analyzer for the Mac. It lists every network in range with its signal, channel, width, generation and security, and shows who is crowding your channel.
Get it on the Mac App StoreFree. Requires macOS 14 or later. Apple silicon and Intel.
Every network
2.4, 5 and 6 GHz, hidden networks included, refreshed every few seconds with signal history for each.
Channel graphs
See which networks overlap and how wide they are, and a ranking of each channel by crowding and airtime in use.
What it supports
Wi-Fi 4 to 7, maximum rate, streams, roaming, beamforming, and security down to the ciphers.
The whole beacon
Every element an access point announces, decoded field by field with the raw bytes alongside.
Group and filter
Group by name, access point or radio. Filter with expressions like signal > -70 and channel = 36, and save them.
Save and export
Keep a scan with its history and reopen it on any Mac, or export the list as CSV.
It only listens
