It's an error message from the `help` function, so seems less likely to be restricted to Macs. I do see that the help() code near the stop() call is the same in both versions. I do not see where `help.search` calls `help`.

Yes, I see that thread. It reports a problem with the MacGUI package manager. That was not the problem reported and in fact both help() and the package manager open correctly. The problem reported was with `help.search()`

There is no R 3.2.0-patched for Mavericks/Yosemite machines. There was a "3.1.3 Patched" for the Snow Leopard platform. I had used the most recent version of R 3.2.0 from the ATT Research site. I  then updated to the release candidate as suggested and R GUI now fails to load with this crash report. Note the error in naming the location of the R target as to be found in 

 /Library/Frameworks/R.framework/Versions/3.3/...

I also see that there was a note: x86_64: make FAILED

Starting R from the a Terminal window succeeds and the error with help.search() does not occur. R 3.2.1 also loads with RStudio with an error reported on startup that I'm pretty sure has already been reported elsewhere.
