HomeBrew saved me. I did not figure out the environment path.
Per referenced blog this Answer (see bottom) was originated from:
(Update 10/06/2020: Step 1 is no longer necessary, just run the brew commands!)
1. Download the two files below from http://www.oracle.com/technetwork/topics/intel-macsoft-096467.html.
This is necessary because of Oracle licenses.
instantclient-basic-macos.x64–11.2.0.4.0.zip and
instantclient-sqlplus-macos.x64–11.2.0.4.0.zip
Put the files in ~/Library/Caches/Homebrew
PS:
in the latest versions of HomeBrew replace the above location
~/Library/Caches/HomeBrewwith~/Library/Caches/HomeBrew/downloads.And also rename the downloaded files with the names suggested by HomeBrew.
Thanks to @manuka_m
2. Next run the following commands
$ brew tap InstantClientTap/instantclient
$ brew install instantclient-basic
$ brew install instantclient-sqlplus
