Apple

Here's a quick look at the main players in the Apple OS world:

• macOS: This is the operating system that powers all Mac computers. It's known for its stability, sleek interface, and a strong ecosystem of creative professional apps. The latest version is macOS 15 Sequoia. It evolved from the original Mac OS (which goes way back!) and has a Unix-based foundation. Think of it as the core of the Apple experience on a desktop or laptop.

• iOS: This is the mobile operating system that runs on iPhones. It's all about touch-based interaction and a huge app store. It's actually the foundation for iPadOS, tvOS, and watchOS. The current stable version is iOS 18. It's the second most popular mobile OS globally, right after Android.

• iPadOS: While it's built on the same base as iOS, iPadOS is specifically tailored for the larger screens and different ways people use iPads. It has features like better multitasking and Apple Pencil support.

• watchOS: This is the operating system for the Apple Watch. It's designed for quick interactions and focuses on fitness, communication, and glanceable information.

• tvOS: You guessed it – this runs on Apple TV. It's all about streaming entertainment and running apps on your television.

• visionOS: The newest addition, this powers the Apple Vision Pro headset, focusing on spatial computing and blending digital content with the real world.
