Tom isn't thrilled with the new iMacs, and Leo recommended he pick up a Mac Mini and get a dock and monitor for it. So he did, and now he wants to move his data from his old mac to his Mac Mini. But the Thunderbolt drives are too expensive. Can he use USB 3 drives? Leo says absolutely. He can also clone the drive and make it bootable. Leo recommends Carbon Copy Cloner since SuperDuper doesn't offer a bootable option now, due to security features in the most recent macOS Big Sur. He can also still use an older version of SuperDuper.
