- At this point, you should have OpenCV 4 and Python installed on your Mac. We can write a small test program that will print the OpenCV version, load an image from the disk, convert the image to gray and show the result. Start by downloading the next image: Save it as clouds.jpg.
- In this post, we will provide a bash script for installing OpenCV-4.0.0 (C and Python 3.7) on macOS – High Sierra and Mojave. We will also briefly study the script to understand what’s going in it. Note that this script will install OpenCV in a local directory and not on the entire system. Let’s jump in 🙂.
- This tutorial provides step-by-step instructions to install OpenCV 4 (with Python bindings) on your macOS machine. OpenCV 4 was released on November 20th, 2018. I originally wrote this blog post when the alpha version was released, and it has now been updated on November 30th, 2018 to support the official release.

Introduction: Opencv and Python Installation for Windows / Mac
OpenCV is an open source computer vision library which is very popular for performing basic image processing tasks such as blurring, image blending, enhancing image as well as video quality, thresholding etc. In addition to image processing, it provides various pre-trained deep learning models which can be directly used to solve simple tasks at hand. The programmers have to download and load the model using OpenCV instructions in order to do the task of inference on their own dataset.
Firstly, you need to install OpenCV library in your system prior to using it for your own dataset. At this stage, there can be two pathways of installing OpenCV in your system namely – (a) Using pip (b) Source Installation. pip is the package manager which is used to install the packages written in python. The difference between installing a python package from source and through pip are given in the table:
Once you have brew installed you can go ahead and and add homebrew/science which is where OpenCV is located using: 1. Brew tap homebrew/science. If you want to see other possible options such as when compiling (such as using tbb) you can use info. Brew info opencv. Go ahead and install OpenCV now.
Step 1: Download OpenCV

Step 2: Download OpenCV-contrib
Download Opencv For Mac
As you can see in the image above, Click on Sources button to download OpenCV – 4.1.0 archive files into your system. Once the download is complete, unzip the files at your desired location. For illustration purpose, I am going to create a folder named as ‘opencv’ in my Desktop and I will unzip the downloaded archive inside the same folder.
In order to download OpenCV_contrib you must open the command line tool and clone the repository by executing the following command:
for windows: https://github.com/opencv/opencv_contrib
then click on Clone / Download
for Mac: git clone https://github.com/opencv/opencv_contrib.git
Step 3: Python Installation
Python doesn’t come prepackaged with Windows /mac, but that doesn’t mean Windows/mac users won’t find the flexible programming language useful. It’s not quite a simple as installing the newest version however, so let’s make sure you get the right tools for the task at hand.
First released in 1991, Python is a popular high-level programming language used for general purpose programming. Thanks to a design philosophy that emphasizes readability it has long been a favorite of hobby coders and serious programmers alike. Not only is it an easy language (comparatively speaking, that is) to pick up but you’ll find thousands of projects online that require you have Python installed to use the program.
Which Version Do You Need?
Unfortunately, there was a significant update to Python several years ago that created a big split between Python versions. This can make things a bit confusing to newcomers, but don’t worry. We’ll walk you through installing both major versions.
When you visit the Python for Windows download page, you’ll immediately see the division. Right at the top, square and center, the repository asks if you want the latest release of Python 2 or Python 3 (2.7.13 and 3.6.1, respectively, as of this tutorial).
for Mac users: https://www.python.org/downloads/mac-osx/
Step 4: Pip Command Installation
After the python installation
go to this url: https://bootstrap.pypa.io/get-pip.py
Now open terminal / command prompt : type python get-pip.py

Hi David, Thanks for the reply. I tried building using step 2a It Works!!!! I am new to mac and openCV. I had trouble installing but your blog made it easy.
Recently, I installed opencv with the following command:
I found opencv3 was installed in dir /usr/include and /usr/lib. But what I want is opencv2. How can install opencv2 with the brew command?
- I’ve been trying to install openCV on my Mac for a week now. I tried following the instructions on the openCV site and they didn’t work. I even tried compiling openCV following their instructions, no love.

The easiest way to find the answer is to use brew search to look for available packages. So, in your case:

I can't give you a answer in context of using brew but I can assist you with a valuable resource that really helped me out when I was first started out with OpenCV that got me up and developing https://www.youtube.com/watch?v=U49CVY8yOxw

Install Xcode , Install C-Make
Download OpenCV source code https://github.com/opencv/opencv/releases/tag/3.1.0
- Build and install!
INSTRUCTIONS: Go inside OpenCV once downloaded create new folder called build. Next, open CMake GUI find the directory we just created ' build ' to build the binaries, Click configure, Select 'Unix Makefiles' and use native default compilers. cd into out build directory in our OpenCV folder so something like this /Users/you/Desktop/openCvFolder/build and run the command 'make' and go have a coffee! I hope this helps it helped me out when I first started experimenting a year ago with OpenCV
