Requires a Mac with built-in Wi-Fi. External Wi-Fi adapters are not supported.

For a more comprehensive analysis of the Wi-Fi environment consider WiFi Explorer, also available in the Mac App Store.

* Due to limitations of the Wi-Fi scanning framework, channel recommendations are based solely on the detection of other Wi-Fi signals, and do not consider external sources of interference or hidden networks (i.e. networks that do not broadcast their SSIDs).
