Где должны лежать бинарники
Conventional places where binary files should live - /usr/local/bin
The short answer: you probably want /usr/local/bin. Depending on how recent your Macos is, you may need to update your default $PATH. See below for further details.
(Update from 12-01-2018) At some point since I wrote my original answer, Apple changed its default $PATH. As a result, a lot of what I say below is irrelevant to recent Macs. If you type echo $PATH in a terminal, and /usr/local/bin is first, then you can ignore everything below about changing your $PATH.
