[R-SIG-Mac] Can't open files in 4.0 or 4.01

[Carl Witthoft]

Hi, I ran  7849 high sierra debug GUI,

and am happy to report that I had zero crashes or hangs.

I tried opening via the icon in the console window, from the File menu, 
and even by selecting a dozen "name.r" files in the Finder and hitting 
<CMD>-O .  All files opened, no problems seen.
