It hangs after this message. > The previous BE boots just fine, so something is broken. I get the same thing trying to install FreeBSD/arm64 -CURRENT on a MacBook Air M2 using UTM. I'm trying to boot FreeBSD-15.0-CURRENT-arm64-aarch64-20241024-8b2e7da70855-273174-disc1.iso and it fails to do so. I have a FreeBSD/arm64 14.1-RELEASE VM that runs under UTM on the same hardware just fine. I guess I just got unlucky choosing that particular snapshot? Something is broken? Cheers, Paul.
