[R-SIG-Mac] Loop when trying to run Rcmdr

[Jose G Conde Santiago]

Hello all.

When I try to run Rcmdr within RStudio on my Mac, I get the following continuous stream of error messages (Session info at the bottom). This is the first time I see this behavior since I started working with Rcmdr years ago. I tried running Rcmdr directly from R, but R freezes. I recently upgraded to MacOS 27 Golden Gate. All I can tell is that there seems to be a problem with tcltk.
