Hmm, there is a problem with bugs.directory default. It is not really a problem, since
we do not know what is the default place for Mac applications? The default also does
not work on Linux if WinBUGS is not strictly installed in "c:/Program Files/WinBUGS14/"
part of wine. The help of bugs() says

...
Operation system support:

MS Windows no problem

Linux, Mac OS X and Unix in general possible with Wine emulation via useWINE=TRUE, but only for WinBUGS 1.4.*

If useWINE=TRUE is used, all paths (such as working.directory and model.file, must
be given in native (Unix) style, but working.directory can be given in Windows path style
(e.g. “c:/Program Files/WinBUGS14/”) or native (Unix) style (e.g. “/path/to/wine/folder/dosdevices/c:/Program
Files/WinBUGS14”). This is done to achieve greatest portability with default argument value for
working.directory.

Unless you can provide a reasonable defaul for Mac, we can not help you!

I wonder where "sh: /Volumes/My: No such file or directory" is comming from. It looks like the path has space
in it. Perhaps we could be more informative in such cases so that users would be warned that bugs.directory
needs to be accomodated.

I will look into other bug later.

Btw. Why do you use setwd(".")? It does not make sense, since this is changing the working directory to
the current one.
