Now that macOS 26 GM is out, and even 26.1 beta is out, where does this all stand? More specifically, does anyone know if using macOS 26 as the host, can we create a macOS 15 VM guest all while allowing us to build and test our apps on both macOS 26 and 15? I still have macOS 15.6 on my only Mac. My app supports macOS 14-26 (well, will support macOS 26 when I can actually test with it). But I have no way to test it in any of the VMs since my app needs a working provisioning profile. Even in a macOS 15 guest on my macOS 15 host, I can't even log into TestFlight to test my app. Will updating to a macOS 26 host allow the macOS 15 guest to at least use TestFlight to download the app for testing? In other words, is there any viable way for a solo developer with one Mac to develop and test a macOS app that runs on more than one version of macOS?
