In the current OpenCV "Installation in MacOS" documentation, some things need to be edited in order to make it more simple for the user.

• In the Installing CMake section, the writer tells us to go to "Tools –> Install For Command Line Use". Unfortunately, "Install For Command Line Use" is not an option. The instructions should tell us to go to "Tools -> How to Install for Command Line Use" and then follow the instructions from the pop-up there.

• Another thing, the writer accidentally labeled the wrong folder name in Step Fixes #1 under the Building OpenCV from Source Using CMake section. This can make it difficult for the user to follow along, since a completely different folder name was used later on.

• In Step added asserts to LBPH code in contrib #2 under the Building OpenCV from Source Using CMake section, there are two bullet points that say "set full path to ___". I think users will benefit more if the documentation was a bit more specific. In this case, it should say "Set OpenCV source code path to ___" and "Set binary build path to ____".

These changes seem fairly simple, I will be making a pull request accounting for these changes soon!
