On my Mackbook Air the default zsh is:
# use `zsh --version` to get this
zsh 5.3 (x86_64-apple-darwin18.0)
I installed the newer version from Homebrew:
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 the next steps.
First, found the location of zsh:
$ which zsh
/usr/local/bin/zsh
Second, found out what’s the shell I was using:
$ 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 and changed the shell:
$ 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:
$ zsh --version
zsh 5.8 (x86_64-apple-darwin18.7.0)
