sudo chmod ugo-x /usr/libexec/path_helper
`path_helper` is intended to make it easier for installers to add new paths to
the environment without having to edit shell configuration files by adding
a file with a path to the */etc/paths.d* directory.
Unfortunately, `path_helper` always reads paths from */etc/paths* set by Apple
then paths from */etc/paths.d* set by third party installers, and lastly paths
from the `PATH` environment variable set by the parent process, which
ultimately is set by the user with `export PATH=...` Thus, it reorders path
priorities, and user */bin* directories meant to override system */bin*
directories end up at the tail of the array.
### Troubleshooting
If you are not able to find certain commands after switching to *Oh My Zsh*,
modify the `PATH` variable in `environment.zsh` then open a new Zsh terminal
