Hi Sam,

First of all, welcome to the OpenCV world! Installation can be a little bit tricky, especially when you're first starting out...

I don't have too much experience with installing OpenCV on Mac OS X, but I've found this guide helpful before:

http://www.pyimagesearch.com/2015/06/15/install-opencv-3-0-and-python-2-7-on-osx/

If you carefully follow these steps, your system should be up in no time!

If you're still having trouble after following the guide, it would be great if you could post some more details about what's going wrong. For example, you mention "file and directory location is wrong", but I'm not sure what that means. Which command did you run? What was the exact error you got from the terminal? etc.

Best,

Michael

If anyone is still having problems with OpenCV 3 and Python 3.5, the easiest way is probably to go with Python's Anaconda distribution:

https://www.continuum.io/downloads

First, follow the platform-specific installation instructions on the website above.

Once Python is installed, go to a terminal and run:

$ conda install opencv

If you get a "package not found" error message, you can search anaconda.org for packages that match your platform:

$ anaconda search -t conda opencv

In the list, pick a user that has the OpenCV version you want for the platform you want.

For example, OpenCV 3.1.0 for 'linux-64' and 'osx-64' is supplied by user `trung`, so simply run:

$ conda install -c trung opencv3

To show more details about a specific package, use:

$ anaconda show trung/opencv3
