We can update vim to a newer version via brew.

Update Vim

brew update
brew install vim

Or use upgrade command as bellow,

brew update
brew upgrade --HEAD vim

The brew installed version Vim is located at /usr/local/bin ，in order to override the old one, we need to export /usr/local/bin to $PATH，open and edit .bashrc/.zshrc：

export PATH="/usr/local/bin:/usr/local/git/bin:/usr/bin:/bin:/usr/sbin:/sbin"

Active the newer vim:

# bash shell
source ~/.bashrc
# zsh shell
source ~/.zshrc
