Some applications started to require a newer version of the bash shell on my Mac. Apple ships a version of 3.2 but Bash is up to version 4.4 and Apple is not able to ship a newer version because Bash 4 uses a GPLv3 license.
I found this quick solution where you use homebrew to install the latest Bash version and changing the terminal configuration to use this new shell.
If you don’t have homebrew it is quite easy with this one command:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"Then you simply have to execute:
brew install bash
Changing the terminal configuration is easy because it is on te first tab of the preferences. Where it says “Shells open with” change from “Default login shell” to “Command (complete path)” and enter this string:
/usr/local/Cellar/bash/4.4.19/bin/bash
Obviously your version may vary depending on what is the latest one available.
