# Install nauty on macOS

I am trying to install nauty on my macos but When I used install_package("nauty") I got the following error

```
__main__:1:
************************************************************************\
********
The Sage function 'install_packages' is currently broken: it does not
correctly install new packages. Please use 'sage -i nauty' from a shell
prompt instead.
This issue is being tracked at
http://trac.sagemath.org/sage_trac/ticket/16759.
************************************************************************\

```

So I tried "sage -i nauty" from the terminal and I got the following error

```
