Installation tutorial for MacOS could use clarification.

Frameworks location could be in other places besides /Library

• MacOS with Homebrew
• 2.5.1

I expected that my Frameworks Folder should be in /Library but realized, after some serious contemplation, I have been using homebrew since day 1 so my Frameworks search path is actually /usr/local/Library. Had I not been aware of this from previous frustrating experiences I wouldn't have known. Perhaps some clarification in the tutorial would help prevent any confusion.
