Speaking of /dev/random, I did a little reading up on Yarrow today after checking the man page.
Yarrow was effectively replaced by Fortuna, and Fortuna was published, according to wikipedia, in 2003. Even the PDF paper describing it has a date of 2010. Linux got Fortuna in 2005. This machine came out in 2014, and is still documented as using Yarrow in 10.9.5, even though that was 10 years out of date by that time. Has Fortuna replaced Yarrow in any later kernel?
