The short version of this is that another tech approached me for help trying to crop down the contents of /System/Library/Fonts/ on one of our users' 10.11 MBP. His argument was "I've always done this in past OS versions, but now I can't." It ended up being SIP stopping him, but I'm still apprehensive about tampering with this. Admittedly, my knowledge of fonts is somewhat limited, and he's been in the business for a very long time.
He's apparently referenced Extensis for this purpose in the past, which claims there's approximately ~40 unnecessary fonts in /System/Library/Fonts/ in 10.11.x. Personally, I think if we're going to start ripping out fonts, limit it to /Library/Fonts/ and ~/Library/Fonts/. And maybe, just maybe - I know this is crazy - actually invest in an enterprise font management system for everybody to use, hopefully preventing that type of thing in the future.
We're a very large print company, and possibly more than normal, fonts are a very big deal. I've heard horror stories about things that went to print and had to be destroyed and redone at great cost to the company, because of font mixups.
Anyway, what's your take?
