	To install OpenCV3 on a Mac, use Homebrew:		To install OpenCV3 on a Mac, and make it usable from Python 3, use Homebrew:

	$ brew install ~~opencv3~~ --with-python3 --c++11 --with-contrib		$ brew install opencv --with-python3 --c++11 --with-contrib
	$ brew link --force ~~opencv3~~		$ brew link --force opencv
	</pre>		</pre>

			You may need to add the <code>--without-openexr</code> flag if you run into compiler errors (hat tip: [https://gravityjack.com/news/opencv-python-3-homebrew/]).
