To install fonts for MS Office 2011 – don’t double click them – this installs them naturally in the user fonts.ONLY TTF fonts work for Office – or so MS claims.Microsoft Office fonts in /Library/Fonts/Microsoft (ahhh I see).system fonts in /System/Library/Fonts (never ever touch these).computer wide (all accounts) fonts in /Library/Fonts.user fonts stored in /Users/youraccount/Library/Fonts.I researched dozens of websites each adding a piece to the puzzle. I now know more about fonts that I ever wanted to know especially how Microsoft fonts fit into the Mac picture. One customer had issues with a critical branding font that installs fine on everyone else’s Macbook but not theirs. When things go wrong – they can sometimes really go wrong. Macs are not perfect even though one’s productivity is much higher with one.
