Solaris and MacOS perhaps, if we are talking strict init. but both of the BSDs use BSD init. There is a push by Jordan Hubbard to get FreeBSD to adopt Launchd (the MacOS init) but so far he has been rebuffed and has instead set out to fork FreeBSD into NextBSD. Frankly this is what should have happened with the likes of Debian regarding systemd as well. A parallel release offering systemd as the default, alongside sysv. Then it would be up to the admins to pick, rather than have to apply contortions during or right after install to switch from systemd to sysv. Instead Debian adopted systemd, and we got Devuan as a sysv fork...
