Habilitar Bash Completion

Lo primero sera establecer por defecto bash en lugar de zsh

chsh -s /bin/bash

Instalamos el gestor de paquetes brew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

La instalacion durara unos minutos, despues reiniciar el Mac. Instalar bash completion

brew install bash-completion

Y para terminar, metemos una linea en el .bash_profile de nuestro usuario

echo "[ -f /usr/local/etc/bash_completion ] && . /usr/local/etc/bash_completion" >> ~/.bash_profile

source ~/.bash_profile
