Why do you like Mac OS?

Apple has recently renamed “Mac OS X” to “macOS”. Mac OS X / macOS is a UNIX operating system based off of the BSD UNIX operating system and initially developed by NeXT Computer as NeXTStep. When Steve Jobs returned to Apple from his time at NeXT, he brought the operating system with him as the replacement for Apple’s System 9 operating system to use in Apple products. Mac OS X debuted in 2002. The operating system consists of a kernel called XNU which is based on a fusion of the Mach micrkernel and the FreeBSD operating system. The kernel, combined with the FreeBSD libraries and runtime applications a is called “Darwin”. On top of Darwin, Apple has added their own GUI system called Quartz and a slew of application frameworks and services that, combined, are called Mac OS X / macOS. The operating system is only licensed to be used on Apple-branded hardware, so you only generally see it on Apple computers. Apple also ships stripped-down versions of macOS that are based on Darwin, but with different application frameworks. These are found on other Apple products. iOS (phones and tablets), TvOS (the Apple TV streaming box), and watchOS (the Apple watch).

Add Pages to PDF: All You Need to Know

All the core applications and services for iOS are built on top of Darwin. The first application of note is the keyboard-based Siri, first brought to iOS with the iPhone. Siri does everything you'd expect from a desktop-class personal assistant: search the web, calendar, phone book or even take calls. All of her basic functions work just fine on the iPhone, but on the Watch you get the full Siri experience, which includes a virtual keyboard instead of the iPhone-based text entry system. She uses the Apple Watch's accelerometer to get directions around the map. Siri supports the “Hey Siri” command, which you'll be more familiar with. “Hey Siri” works by saying “Hey Siri,” then say “Hey Siri” again and her assistant will respond. With the release of the Apple TV in 2015, it's possible to use Siri to launch apps and run other commands on that.
