Basically every computer hardware manufacturer is collecting telemetry and sending it home. If you’re using MacOS or Windows, your OS is doing it aswell
Or Android, or iOS, or a Chromebook, or whatever other OS you're using next year, if it isn't some sort of Linux/UNIX system... and even some of those might not be great, but at least you can find out.
I mean.. Android and ChromeOS are Linux underneath. MacOS is.. related to Unix. Hang on, I need to look up that lineage..
Also Lineage.
Edit: MacOS used/uses the Mach kernel, and uses code “derived from BSD”, vague as Wikipedia is. That could mean it’s a whole copy-paste or that it just borrows ideas from BSD.
MacOS has userland tools from some FreeBSD version (quite obsolete, IIRC). Also there's a port of bhyve called xhyve for MacOS. Its kernel I wouldn't expect to have much in common with BSDs.
