This is a very reasonably request, and all useRs who benefit from the
tireless work of R-core should consider doing it.  I have considered
it, but compiling R from sources on OS X has been my stumbling block.
At least last time I tried I got stuck at the  Fortran step. It doesn't
 help I have very limited experience compiling  software of the complexity 
of R.  Really, I've only done it within the warm welcoming confines of the
 vagrant image Tomas Kalibera set up for `rchk`.

I also use r-devel on docker, but that isn't very practical for
day-to-day usage, which is what I think we need.

What would it take to generate pre-release binaries for OS X (and Windows)?  I
imagine if such were available the volume of testers would increase
dramatically (at least, I haven't seen them if they exist).  
Maybe something the R Consortium would consider funding?
