Alright, got this to reproduce with emacs -Q

M-x wasn't working for me in emacs -Q on Mac so I had to be a bit inventive.

I'm guessing it is a darwin specific issue like you said.

Exact steps for me:

Start with emacs -Q

Put: (global-set-key (kbd "<f2> a") 'auto-revert-mode) in *scratch*

Run above lisp command using C-x e

C-x f ~/test.txt

<f2> a

*** It says Auto-Revert mode enabled in current buffer. ARev shows in mode
line ***

In separate terminal, echo "blargh" > test.txt

*** Nothing happens in test.txt buffer. ***
