I've recently had to rebuild my laptop and needed to setup M$ fonts for work. The top hit for installing fonts is a stack exchange thread pointing to a 3rd Party download, given that I knew that office came with the fonts, I just needed to figure where they were.

Assuming you don't have MS office installed, here's a quick 4 step install....

-- If you do have office, start at 3

1. Install Cask
2. Install Microsoft Office brew cask install microsoft-office
3. Make a directory: mkdir ~/Library/Fonts/Microsoft
4. Copy the fonts: cp -av /Applications/Microsoft\ Word.app/Contents/Resources/Fonts/* ~/Library/Fonts/Microsoft/

Enjoy!
