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.
