こちらのサイトを参考にさせていただき、mac book proにopencv3をインストールしました。 HomebrewでMacにOpenCV3をインストールしてPython3で使う
macの環境はこちら

Required: python ✘, python3 ✔
==> Caveats
Python modules have been installed and Homebrew's site-packages is not
in your Python sys.path, so you will not be able to import the modules
this formula installed. If you plan to develop with these modules,
please run:
mkdir -p ~/.local/lib/python3.5/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/.local/lib/python3.5/site-packages/homebrew.pthオプションを確認すると色々と要求されていたり、 「Build, Required」など×がついているものが多かったので対応した。
対応した時に打ったコマンド
$ brew install cmake pkg-config jpeg libpng libtiff eigen openexr jasper tbb qt5
$ brew upgrade cmake
$ brew upgrade libtiff
$ mkdir -p ~/.local/lib/python3.5/site-packages
(余計だったかも)$ echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/.local/lib/python3.5/site-packages/homebrew.pth
$ brew upgrade ffmpeg (インストールしていない場合は $ brew install ffmpeg)
$ brew upgrade numpy (インストールしていない場合は $ brew install numpy)
$ brew install python対応後
$ brew info opencv3

インストール
$ brew install opencv3 --with-contrib --with-examples --with-ffmpeg --with-jasper --with-opengl --with-python3 --with-qt5 --with-tbb --without-numpy実は、すでにopencvが入っている人はこっち。
$ brew upgrade opencvそれなりに時間がかかります。
確認
インストールが終わったらopencvのビルド情報を確認。
$ python -c "import cv2; print(cv2.getBuildInformation())"

-----------------------------------------------------------------これで、macでopencv3を使えます！
Anacondaでopencv3を利用する場合
Python3 OpenCV3 for Linux/Mac をインストールする
上記のサイトを参考にさせていただきました。
すでに作ってあった環境で試してみる。
$ source activate face_authentication
$ python -V
Python 3.5.3 :: Continuum Analytics, Inc.opencvをインストール
$ conda install --channel https://conda.anaconda.org/menpo opencv3確認(失敗編)
$ python -c "import cv2; print(cv2.getBuildInformation())"
Error in sitecustomize; set PYTHONVERBOSE for traceback:
KeyError: 'PYTHONPATH'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/cv2.so, 2): Symbol not found: _PyCObject_Type
Referenced from: /usr/local/lib/python2.7/site-packages/cv2.so
Expected in: flat namespace
in /usr/local/lib/python2.7/site-packages/cv2.soなんかエラーが出てる。
原因
pyenvが壊れた？PYTHONPATHエラーでPython3.xが起動時に2.xのモジュールを参照する件
調べてみると、どうやらhomebrewで設定しているパスがおかしかったみたいです。 ってか最初のopencvのインストールで余計なことをやっていた可能性が高いです。。。
余計なことをやったと思われるコマンド
$ echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> ~/.local/lib/python3.5/site-packages/homebrew.pth対応
$ cat ~/.local/lib/python3.5/site-packages/homebrew.pth
import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")環境はpython3.5なので、修正をする。
$ vi ~/.local/lib/python3.5/site-packages/homebrew.pth
import site; site.addsitedir("/usr/local/lib/python3.5/site-packages")再確認
$ python -c "import cv2; print(cv2.getBuildInformation())"
~~省略~~

気になったのでメモ
Install OpenCV for Python on Mac OS X or Linux
