One of the suggestions in
https://cran.r-project.org/doc/manuals/r-devel/R-exts.html#Debugging-on-macOS
should help. Both worked for my build of R-devel yesterday ....

I can start it from the /Users/murdoch/R/R-devel/lib directory where
libRblas.dylib lives. Setting DYLD_LIBRARY_PATH or LD_LIBRARY_PATH to
point there doesn't help (either on the bin/R command line or exported).
Is there some other way to run it from whatever directory I happen to
be in?

Vince,
Apple no longer allows debugging of distributed apps - see R for Mac
FAQ 10.17:

Another (not recommended) work-around is to disable SIP.
Cheers,
