# Download an executable for macOS

LAMMPS can be downloaded, built, and configured for macOS with
[Homebrew](https://brew.sh)\_. (Alternatively, see the installation
instructions for [downloading an executable via Conda](Install_conda).)
The following LAMMPS packages are unavailable at this time because of
additional requirements not yet met: GPU, KOKKOS, MSCG, MPIIO, POEMS,
VORONOI.

After installing Homebrew, you can install LAMMPS on your system with
the following commands:

``` bash
brew install lammps
```

This will install the executables \"lammps_serial\" and \"lammps_mpi\",
as well as the LAMMPS \"doc\", \"potentials\", \"tools\", \"bench\", and
\"examples\" directories.

Once LAMMPS is installed, you can test the installation with the
Lennard-Jones benchmark file:

``` bash
brew test lammps -v
```

The LAMMPS binary is built with the [KIM package](kim), which results in
Homebrew also installing the [kim-api]{.title-ref} binaries when LAMMPS
is installed. In order to use potentials from
[openkim.org](https://openkim.org)\_, you can install the
[openkim-models]{.title-ref} package

``` bash
brew install openkim-models
```

If you have problems with the installation, you can post issues to [this
link](https://github.com/Homebrew/homebrew-core/issues)\_.

Thanks to Derek Thomas (derekt at cello.t.u-tokyo.ac.jp) for setting up
the Homebrew capability.
