KisMAC - an open-source WiFi analyzer application for Mac OS that can map wireless networks and lay out the info on their performance so you can easily troubleshoot. We wanted to continue the apparently stagnant project. KisMac Reloaded is a fork of the Mac OS X wireless stumbler KisMacNG. Mac Wireless Diagnostics Tool - a built-in Mac WiFi analyzer that’s included in all version of macOS.
KisMACmakes the most of the power of the AirPort and AirPort Extremecards, but it's also compatible with others like PCMCIA Orinoco, PrismII, Cisco Aironet, Atheros and PrismGT, or USB devices with Intersil Prism2, Ralink rt2570 or rt73 chips, that are also commonly found on the market. On many occasions, it is necessary to search for wireless networks, so if you notice that the client integrated into Mac doesn't find any networks to connect to, it is possible that KisMAC will be able to help you.
