dyld[52867]: Symbol not found: _libiconv

Your path of least resistance is
brew install juliaup
Otherwise, you may have conflicting dynamic library linkages due to multiple versions of the same library being installed due to conda, for example.
Thanks - I have juliaup running, and was able to set to 1.12.6 , after doing an app install via the .dmg download.
