You’ll need to wait patiently as this figure indicates: Figure 1: Xcode is a dependency for Homebrew and therefore OpenCV 4 on macOS. To install Xcode, fire up the Apple App Store, find the Xcode app, and install. I’ll cover alternative methods (pip and Homebrew) in future installation guides (neither of these methods can be covered until OpenCV 4 is officially released).įinally, we’ll test out our OpenCV 4 install and get our feet wet with a real OpenCV project. Compiling from source allows us to have full control over the compile and build as well as to install the full OpenCV 4 build. I post links to all my OpenCV install tutorials there.įirst, we’ll install Xcode and set up Homebrew.įrom there, we’ll establish Python virtual environments. Note: If you landed on the wrong install tutorial (perhaps you want to install OpenCV on Ubuntu or your Raspberry Pi), then you should visit my OpenCV installation guides page. OpenCV 4 is packed with new features, many of which are deep-learning focused. In this blog post we’re going to install OpenCV 4 on macOS. Looking for the source code to this post?
