Okay, I just pushed a release and notarized. Works great on my test laptop (macOS 26.2) and my test desktop (macOS 14.x)
But it seems to fail for a friend who's running macOS 15.
I've been using the same GitHub actions successfully for months.
How can notarization work for macOS 14 and 26, but not for macOS 15?
I think everything looks okay as far as the signing?
I've checked codesign -dvv
