I’m having an issue installing my TestFlight build on a Mac. The build (v1.0 build 1) uploads successfully and shows as “Complete” in App Store Connect. I can also open the build details page, and my Apple ID / tester access / group setup looks correct.
However, on TestFlight (macOS), when I tap Install/Load, I get this error: Unable to install. The requested app isn’t available or can’t be found.
Notes: The app is an iOS app (iPhone + iPad), and I enabled availability for Mac (Designed for iPad) in App Store Connect. The Mac is Apple Silicon, running macOS Tahoe 26.1.
Could you help me understand why TestFlight shows this message on Mac, and what I should change in Xcode/App Store Connect to make the build compatible?
