How to change bash version with homebrew
You'll need to change your account's login shell from System Preferences, Users &amp; Groups. You need to access the Advanced Options by right-clicking on your username and changing your shell to /usr/local/bin/bash. Once you've done that, restart Terminal.app (to make sure no old sessions with the wrong shell are left hanging around) and you should be set.



You can do the same using dscl:

dscl . -change /Users/&lt;username&gt; UserShell /usr/local/bin/bash
