I've searched these terms all over the place and have found only a confusing mishmash of things that were probably true years ago but no longer seem to reflect today's reality so I'm posting it here to hopefully add a definitive 2026 answer to these search results for myself and others. The existence of the DNS Proxy Network Extension protocol in 10.15 has given me an idea. I would like to test this idea to see if it is worth developing further or a complete waste of time. This test does not need to run on any device anywhere in the world other than the one in front of me so I would prefer not to spend $100 just to see if I can make a small code fragment do a silly trick. XCode sadly refuses to build my Network Extension target when I only have a "Personal Team" to sign with: Personal development teams, including "XXXX XXXX", do not support the Network Extensions capability. Can this be done or is Apple just 100% pay-to-play nowadays? I have zero problems disabling SIPS or any other consumer grade protections if that will actually achieve my goal but I've read enough comments from people saying it didn't work that I haven't bothered trying. Thanks for reading. OS: 15.7.5 (24G624) XCode Version 26.3 (17C529)
