# macOS Ensure ZSH Default Shell
|
||
|
|
|
||
|
|
Ensures ZSH is configured to be used as the default command-line shell
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
This script ensures ZSH is used as the default shell by ensuring it is added to `/etc/shells`. The script
|
||
|
|
also ensures ZSH is available at `/usr/local/bin/zsh` on ARM64 systems by symlinking the Homebrew ZSH shell
|
||
|
|
to `/usr/local/bin/zsh` if it is missing.
