# macOS Bash v4 Upgrade Instructions
When using the `run_embark <cmd>` commands, you receive the error `ERROR: this script requires Bash version >= 4.0` on macOS, follow the steps below to upgrade bash to v4:
1. Install HomeBrew (if not already installed):
`ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"`
2. Update HomeBrew packet database and install bash:
`brew update && brew install bash`
3. Change your application to use the correct shell. For example, in Terminal, open Preferences, then change *Shells open with:* to `/usr/local/bin/bash`:
