    # [macOS] Install unrar tool from source

    Instructions on how to install the `unrar` command on macOS from source.

    ## Prerequisites

    macOS Command Line Tools need to be installed on your local computer.

    To install the Command Line Tools run the following command:

    ```sh
    xcode-select --install
    ```

    ## Get the source

    To obtain the GNU Tar tool source code run the following commands:

    ```sh
    mkdir -p ~/.src/unrar
    curl --silent --location --retry 3 "https://www.rarlab.com/rar/unrarsrc-7.1.6.tar.gz" | tar xz --no-same-owner --strip-components=1 -C ~/.src/unrar
    cd ~/.src/unrar
    ```

    ## Configure

    No configuration required.

    ## Build

    To build the source code run the following command:

    ```sh
    make --silent --no-print-directory -f makefile unrar
    ```
