I tend to agree with this take; as a pedantic side note, though, I’m not sure that OS X was ever based on FreeBSD – they took the userland, sure; but from the very start, the kernel was derived from the Mach kernel, which itself was a fork of the 4.3BSD kernel. I’m sure they’ve helped themselves liberally to the FreeBSD kernel for features; though still, OS X never was ‘based on’ FreeBSD (let alone a ‘FreeBSD with a pretty coat of paint’, as people like to say).
