# Installing Fish shell on MacOS (Intel and M1) using brew

[Fish](http://fishshell.com/) is a smart and user-friendly command line (like bash or zsh). This is how you can instal Fish on MacOS and make your default shell.

Note that you need the https://brew.sh/ package manager installed on your machine.

## Install Fish

`brew install fish`

## Check the path
Check the fish path with  `which fish `. In the examples below it was located at: `/opt/homebrew/bin/fish`
On older Macs default path is `/usr/local/bin/fish`, replace accordingly in the instruction below.


## Make `fish` the default

1. check the fish path with `which fish`. In the examples below it was located at: `/opt/homebrew/bin/fish`. On older Macs the path might differ.
2. **Add fish to the know shells**

3. Restart your terminal
