##Step 1 You need install numpy already in your Mac in order to install cv.py and cv2.py which are the library of Python automatically (OpenCV will be installed by brew at /usr/local/Cellar/opencv/version/)

##Step 2 Install OpenCV

brew tap homebrew/science

If the numpy had been installed already,you can do next:

brew install opencv

Next , you need to back to the directly of Python

• if you are using virtualenv,it should be here

cd ~/.virtualenv/name/lib/python2.7/site-packages

• Otherwise:

    cd /Library/Python/2.7/site-packages/
  

Link the Python with OpenCV

ln -s /usr/local/Cellar/opencv/2.4.9/lib/python2.7/site-packages/cv.py cv.py
ln -s /usr/local/Cellar/opencv/2.4.9/lib/python2.7/site-packages/cv2.so cv2.so

##Step 3 Test you Python. It is Ok if it shows like below

➜  ~  python
Python 2.7.8 (default, Oct 16 2014, 05:18:45) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.51)] on darwin
Type "help", "copyright", "credits" or "license" for more information
>>> import cv
>>> import cv2
