This is a short note about getting started with Java 11 LTS or Java 13 on macOS Catalina. As you probably know, starting with Java 11 there was a big change in the license under which the official Oracle JDK is provided. In short, you need to buy a license from Oracle if you want to use the official JDK in a commercial setting. As far as I know, using Oracle’s JDK on your private computer for testing and learning purposes is allowed.
That being said, for most users OpenJDK is the new JDK of choice, it is provided under an open source license and you don’t need to pay for using it.
There is also a video version of this tutorial:
- Note: The pre-built OpenCV packages don’t support cameras in WSL. Unless you compile OpenCV with FFMPEG and GStreamer in WSL, the live demos won’t work with any cameras. Alternatively, you use a video file as input. Follow the instruction to install Windows Sysystem for Linux (Ubuntu). Install Windows ADB and start the ADB server in Windows.
- Packages for standard desktop environments (Windows, macOS, almost any GNU/Linux distribution) run pip install opencv-python if you need only main modules; run pip install opencv-contrib-python if you need both main and contrib modules (check extra modules listing from OpenCV documentation) b. Packages for server (headless) environments.

Jul 06, 2020 This tutorial explains how to install OpenCV in Qt on macOS (OSX). As I couldn't find a video tutorial, I decided to do it myself, after I found how to do it. I hope this can help you. Note: If you failed to install it due to any kind of issue then remove environment and try to again set it up. To remove type conda env remove -n ComputerVision Step 4b: Installing OpenCV (2/3.
At this time, Java 11, the long term release or LTS, of Java is no longer supported on the OpenJDK website. You can still get the archived version, but this is not recommended because it doesn’t include any new security patches. If you still need to use Java 11, use an alternative build like the one from AdoptOpenJDK. From the AdoptOpenJDK page you will download a pkg file that you can install on your macOS machine directly by double clicking on it.
After you’ve installed the AdoptOpenJDKpkg file, check if you can use it with:
This is what I see on my machine:
If you prefer to use the Java version provided by the OpenJDK website, you will need to use Java 13. Start by getting OpenJDK, chose the macOS version. Extract the archive by double clicking on the file or, assuming it is in your Downloads folder, write this in your Terminal:
Install Opencv Macos
Next step, is to move the extracted folder to a place where macOS searches for Java JDK:
Now, check if you’ve successfully installed the JDK with:
This is what I see on my machine:
Just to be sure that everything works, try to compile and run a simple program:
Save the above as HelloWorld.java and compile it with:
If you want to run the compiled version:
This is what I see on my machine:
Side note, you can also run directly the program, without the separate compilation step with:
but this is usually slower than compiling the code with javac and running the compiled code.
Hi All,
Install Opencv For Macos Download
Currently I'm installing the openCV on my computer, and it report an error like this:
One of my mates has already installed opecv on his system(Mac OS El Captain) successfully without this error.
I thought this problem may be caused by latest update on Mac OS. I checked the update and Apple said the CVKit has already replaced QTKit.
Does anyone has some ideas about how to solve this issue? I'm be grateful indeed if you can help me!

Please check the text version again, Thx!
no idea about apple, but you should watch this
oh shit i just upgraded all my boxes to macos Sierra :-)
my stuff still works, haven't recompiled opencv yet though. What is CVKit ? I'm not sure what QTKit is either actually - but it looks like it's part of highgui (probably uses QT).
And as it seems part of opencv, what were youre steps before you downloaded opencv?Alternatively - try using homebrew.
