<p>Yes. It has changed! Now I typed <code>zsh --version</code> it showed the new one:</p>
<pre><code class="lang-bash">$ zsh --version

On my Mackbook Air the default zsh is:

```bash
# use `zsh --version` to get this
zsh 5.3 (x86_64-apple-darwin18.0)
```

I installed the newer version from Homebrew:

```bash
brew install zsh
```

Although, Homebrew installed the newer version (which is 5.8), when I checked it, it was still 5.3.

Then, I tried next steps. 

## First, find the location of zsh:

```bash
$ which zsh
/usr/local/bin/zsh
```

## Second, found out what's the shell I was using:

```bash
$ dscl . -read /Users/<username> UserShell
UserShell: /bin/bash
```

The `.` is short for _localhost_, the `<username>` expands to my username on the Mac.

## Third, I added the zsh's location to the shell file:

```bash
$ sudo vim /etc/shells
# add `/usr/local/bin/zsh` at the bottom in it

# use the next command line to change shell
$ chsh -s /usr/local/bin/zsh

# confirm whether it has changed
$ dscl . -read /Users/<username> UserShell
UserShell: /usr/local/bin/zsh
```

Yes. It has changed! Now I typed `zsh --version` it showed the new one:

```bash
$ zsh --version
zsh 5.8 (x86_64-apple-darwin18.7.0)
```
