OSX is not BSD. It's Unix. Some people think it's based on FreeBSD but its core is Mach with FreeBSD components.
I am not convinced MacOS is more secure because it is a BSD.
My point about security is that, unlike Windows, any Unix/Linux/BSD system only allows installation, reading and execution if given the permission to do so and therein lies major security compared to Windows where driveby installation and execution is the norm.
As far as updates on OSX go, I don't know, I don't own a Mac.
