A good example of this is how AirMagnet Survey lost most of it's market share to Ekahau, which eventually brought out a MacOS version of it's Wi-Fi modelling and survey software. Many of the legacy applications that didn't bring support to MacOS eventually became obsolete. The lack of dual OS support still left many needing multiple devices to complete their tool-kit. MacOS quickly became a popular device of choice for Wireless Professionals but many of the applications required the Windows OS to run. Use the Wireless Toolbar to configure the desired channel and channel width. Then it became widely known that Apple MacBooks were able to switch their built-in Wi-Fi interface to monitor mode for native wireless sniffing. The Wireless Toolbar will appear just below the Main toolbar. The cost of these tools meant that it was difficult for the average Network Engineer to be readily equipped with such capabilities. There was also AirMagnet Wi-Fi Analyzer that required a specific AirMagnet card and driver for packet analysis and Wi-Fi troubleshooting. An AirPcap USB interface was a pretty coveted device in the 2010's as it allowed for sniffing of 802.11n wireless frames directly in software like Wireshark on a Windows laptop. What this means is that compared to other similar tools out there, the user has 100 freedom to make any changes to it and use it with any kind of apps he wants, regardless if the applications are commercial or freeware. In the old days if you wanted to do wireless protocol analysis you really needed some specialised equipment. One of the many great features of WinPcap is the fact that it's released under the BSD open source license.
