This link contains links to installation instructions for Linux, Windows and iOS, but not macOS.

A lot of macOS users will know that they can probably use the instructions for Linux (they can right? I'm not 100% sure) - but it's not safe to assume that they all will. Also, the Linux instructions do not mention that they can work on macOS, too (they only sayThe following steps have been tested for Ubuntu 10.04 but should work with other distros as well.).

I don't have too much knowledge about OpenCV, but I feel like those instructions (for Linux, for example) should be updated. The fact that they mention testing on Ubuntu 10.04 is a hint towards that. They are also 100 lines long (if counting a few whitespace-only lines) and yet never mention installing via something like apt-get opencv. Is there a reason there isn't a package manager installation? I found instructions to install with brew on macOS, could that just be added there?
