Description

Please describe the issue and what steps we can take to reproduce it:
Migration Assistant does not appear to support “Share Disk,” the Apple Silicon equivalent of “Target Disk Mode.”
I attempted to migrate data between two A2442 MacBookPro18,4 (14” MacBook Pro 2021) machines both running 12.2.

With the source machine in Share Disk mode (Boot to recovery, Utilities > Share Disk), the two machines connected by a brand new 0.8m Apple Thunderbolt3 cable, the destination machine running Migration Assistant reports “Looking for sources…” forever.
From the Finder on the destination machine, I can Browse Network (as explained in https://support.apple.com/en-sa/guide/mac-help/mchlb37e8ca7/mac) and connect to the source machine, so I know the Thunderbolt connection is working.

Because Migration Assistant directs users to plug in a Thunderbolt Cable to speed transfers, this mode of connection should work.
