What is macOS?

macOS is the operating system that runs on Apple’s Mac computers. It’s the software layer that lets you interact with the hardware, run apps, and manage files, all with a user-friendly graphical interface.

Let's break it down

  • Operating system: the basic program that controls a computer’s hardware and lets other software work.
  • Apple’s Mac computers: laptops and desktops made by Apple, like the MacBook Air, MacBook Pro, iMac, and Mac mini.
  • Software layer: a middle level between the physical parts of the computer (CPU, memory, etc.) and the applications you use.
  • User-friendly graphical interface: visual elements like windows, icons, and menus that you can click with a mouse or trackpad instead of typing commands.

Why does it matter?

Understanding macOS helps you choose the right computer for your needs, troubleshoot problems, and get the most out of the apps you rely on. It also matters if you work with others who use Macs, because file sharing and collaboration are smoother when you know the basics.

Where is it used?

  • Creative professionals (photographers, video editors, designers) who use apps like Final Cut Pro and Adobe Creative Cloud.
  • Education settings, where schools provide Mac labs for coding, graphic design, and general learning.
  • Business environments that value security and integration with other Apple devices (iPhone, iPad).
  • Home users who want a simple, reliable computer for web browsing, media consumption, and personal projects.

Good things about it

  • Seamless integration with iPhone, iPad, and Apple Watch (Continuity features).
  • Strong focus on security and privacy, with regular updates.
  • Polished, intuitive design that’s easy for beginners to learn.
  • High stability; crashes and system slowdowns are rare.
  • Built-in creative and productivity apps (Photos, iMovie, Pages) that work out of the box.

Not-so-good things

  • Limited hardware choices; you can only run macOS on Apple-branded machines.
  • Higher upfront cost compared to many Windows PCs.
  • Some specialized software, especially in engineering or gaming, may not be available or run slower.
  • Less flexibility for deep system customization or hardware upgrades.
