I installed B3 MAC and let it port from 18.0.3 version. I drug the Open window in order to split it away from the projects/defs/class/symbols. This all worked fine.
My projects are each setup with a different working directory. With B3, the open window does not update to the proper directory yet the editor says the working directory was changed. Notice in the attached file that right after I switched projects, the editor put a msg in the lower left corner that "Current directory is /Users/russ/copperInc" yet the open window just above it is showing "../russ/ion-open-source/".
