I "solved" this issue finally by disabling my Intego VirusScan and then opened the .dmg.app again. The verification process proceeded without incident. Scanned the resulting .app with ClamXAV: seems OK. Was able then to open the app and use it.
But _something_ is odd about the .dmg's for this new version of Sage. The interference with VirusScan (if that's actually what caused the problem) has never occurred with earlier versions of Sage or with a host of other downloaded .dmg's, including very large ones (e.g., Mathematica).
