- For more information see the FreeBSD porters handbook. GNU aka GNU/Hurd. The official name of this operating system is GNU. Hurd is the kernel in the GNU operating system. It is often listed as GNU/Hurd since there is also GNU/Linux and GNU/kFreeBSD, which are most of the GNU operating system with the Linux and FreeBSD kernels respectively.
XNU (acronym for 'X is Not Unix') is a hybrid kernel based on Mach and BSD which is used in OS X. It was developed to replace the obsolete classic Mac OS (Mac OS 9 and older) kernel, which had poor memory protection and cooperative multitasking.
Quaestum facere mac os. The history of macOS, Apple's current Mac operating system originally named Mac OS X until 2012 and then OS X until 2016, began with the company's project to replace its 'classic' Mac OS.That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system.
https://atzvrybigwinslotsschoolscasino.peatix.com. macOS is an Apple's mostly proprietary operating system for Macintosh computers, which is, in fact, able to be run on any modern x86-64 computer; it also has a mobile version, iOS, and other specialised editions: tvOS and watchOS.
Darwin is a distribution of core open source components of OS X and iOS.

Features
XNU inherits some BSD features:
- POSIX system calls;
- some BSD extensions;
- Mandatory Access Control (MAC).
And XNU and OS X introduce a lot of specific features, including:
- own sandboxing system;
- own file system hierarchy (with FHS preserved);
- Apple Events and FSEvents;
- OpenDirectory, an authentification system;
- SystemConfiguration, a modular configuration mechanism;
- Apple System Log (ASL);
- AppleScript;
- notifyd and distnoted, notification (IPC) mechanisms;
- launchd, an initialization system, network manager and other things all-in-one;
- Mach APIs;
- IOKit framework, which allows interfacing with kernel mode drivers for user space programs;
- and more.

Code signing
OS X and iOS support code signing. In OS X it can be disabled, but in iOS it is a heavy protection mechanism, which allows only reviewed apps to be run. However, Apple sells developer and enterprise certificates which can be used to distribute malware; a user only needs to install a profile. There also were a vulnerability which allowed to install outdated profiles by resetting the date. Apple can easily block certificates.
Entitlements
https://download-yy.mystrikingly.com/blog/project-camino-mac-os. An entitlement is simply a permission written for a binary; even with root access it is not possible to override them. For example, running a program which uses task_for_pid Mach call under root without the required entitlements will result in an error. Of course, entitlements are signed.
Sandboxing
This feature is present in both OS X and iOS, but in iOS it is much harder. In fact, it is a jail, which places applications inside their own environment, from which they can only access their own root. More about app sandbox here.
