 4. Make directories where you want to install radiance, for example ``~/.local/opt/radiance``. Some users have reported that the installer for MacOS isn't descriptive about where it installs, and they have an easier time just choosing a location by pressing the "Change Install Location..." button in the "Installation Type" stage of the install. Then they source it in the bash/zsh_profile like so::
