The remainder of this blog post demonstrates how to install OpenCV 3 with both Python 2.7 and Python 3 bindings on macOS via Homebrew. Install OpenCV 3 on macOS with Homebrew (the easy way) To discover the easy way to install OpenCV 3 on macOS via Homebrew, just keep reading. You lose a bit of control (as compared to compiling from source), but what you gain is an easier to follow path to installing OpenCV on your Mac system. Well, thereвЂ™s a little more to it than thatвЂ¦ but the process is greatly simplified. So, is it really that easy?

вЂњIs there an easier way to install OpenCV on macOS? A way that avoids the complicated CMake configuration?вЂќ The downside is that determining the correct CMake paths to your Python interpreter, libraries, and include directories can be non-trivial, especially for users who are new to OpenCV/Unix systems. Over the past few weeks I have demonstrated how to compile OpenCV 3 on macOS with Python ( 2.7, 3.5) bindings from source.Д¬ompiling OpenCV via source gives you complete and total control over which modules you want to build, how they are built, and where they are installed.ДЄll this control can come at a price though.
