### Mac OS X

|

If you have administrator privileges, you must fix an Apple misconfiguration in
|
||||
Mac OS X 10.7 Lion by renaming `/etc/zshenv` to `/etc/zprofile`, or Zsh will
|
||||
have the wrong `PATH` when executed non-interactively by scripts.
|
||||
If you have administrator privileges, you must fix an Apple-introduced problem
|
||||
in Mac OS X 10.5 Leopard by executing the following command, or BASH and Zsh
|
||||
will have the wrong `PATH` when executed non-interactively.
|
||||
|
||||
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
|
||||
modify the `PATH` variable in *environment.zsh* then open a new Zsh terminal
|
||||
window or tab.
