I think the terminal settings in the GUD buffer must be different for recent
Macs.

Try:

(gdb) shell stty -onlcr

(assuming "shell stty -a" gives onlcr).

Emacs doesn't expect the extra ^M characters and so it fails to parse the
output correctly.  If modifying the terminal doesn't work (but I think it
should), you could try changing gud-gdb-marker-regexp and
gud-gdb-marker-filter to look for ^M\n instead of just \n.
