After building docker from the git repo, you can run
```
./contrib/mac-install-bundle.sh install
```
and this will tell Docker for Mac to look for a bundle at the current
path to run instead of the built in version of Docker. This will persist
until you do a factory reset or run
```
./contrib/mac-install-bundle.sh undo
```
A factory reset is advised to reset as a development Docker may break your
install.
The path must be a path that is shared with Docker for Mac so that the VM
can find it - nothing is installed into the image.
This is in `contrib/` as it is a best effort attempt to make it easier for
Docker for Mac users to test master or pull requests. If it breaks anything
a factory reset is your friend.
