OS X is not quite Unix/Linux, so I don't really know, but I'd suspect
that somehow the environment variable that describes the terminal
capabilities (usually called TERM) got unset or not set properly for
the terminal emulator in which you are running R. How exactly are you
starting R? What is the output of
Sys.getenv("TERM")
Sys.getenv("PAGER")
options("pager")
?
