I have not personnally used R on Mac, so someone else will have to respond
to the primary question. I do have some comments below on secondary questions.

I am surprised that that these two lines appear only the first time a
directory is used, not after restoring .RData.

What is that prompt that that came through the email as "ESC [0m"?
Are the options set correctly?
Do you have gnuclient on the MAC? What happens when you type
edit(anova)
page(ls)
?

Open a file "tmp.r". In the Emacs Menu bar, what is the contents of the
ESS/Start Process/other/
menu item?
