# Pick and choose what you want, as all models don't NEED to be tested at this depth.

Installation

Go to the official website and choose your OS.

MacOS

Docker for Mac has a problem is the disk IO performance (see docker/for-mac#77).

There is a fix (https://github.com/IFSight/d4m-nfs) which makes Docker use NFS instead of OSXFS.
