Windows vs macOS vs Linux: Differences, Pros and Cons Compared

License, price and philosophy

The most concrete difference between the three systems, the one you feel before even turning the computer on, is how you pay for it. Windows follows a one-time commercial license model per device: at Microsoft Store list price, the Home edition costs $139 and Pro $199.99, with an upgrade from Home to Pro priced at $99.99 (US market prices checked on September 6, 2026). In everyday practice many users never pay this amount directly, because the PC manufacturer already bundles it into the price of the machine, but the license remains a product separate from the operating system itself.

macOS has no standalone price: it’s included in the purchase of a Mac and is never sold as an independent product, because Apple distributes it exclusively for its own hardware. Linux, by contrast, is free to download, use and redistribute: the kernel is covered by the GNU GPL version 2 license (GPL-2.0 only), which guarantees four basic freedoms — running the program, studying its code, sharing it and modifying it — plus the right to redistribute it and even sell it, as long as recipients can rebuild the binaries from the source code. Distributions like Ubuntu stay free even for everyday use; you only pay if you choose extended enterprise-grade support, such as an Ubuntu Pro subscription.

	License and cost	Who controls it
Windows	Paid per device (Home $139, Pro $199.99 at Microsoft Store list price)	Microsoft
macOS	Included in the price of Apple hardware	Apple
Linux	Free, GPL-2.0 license (kernel); individual files can also use compatible licenses like LGPL, BSD, MIT	Open source community, no single company

Compatible hardware

Windows runs on a very wide range of computers from different brands, from budget laptops to workstations, as long as they meet precise minimum requirements: Windows 11 needs a 64-bit processor with at least 2 cores at 1 GHz or faster, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot, and a TPM (Trusted Platform Module) 2.0 chip — that last requirement, in particular, locked many older PCs out of the free upgrade. For the more advanced AI features reserved for so-called “Copilot+ PCs,” it also takes an NPU rated at 40 TOPS or higher, 16 GB of DDR5/LPDDR5 RAM and 256 GB of SSD or UFS storage.

macOS follows the opposite philosophy: it officially runs only on Mac computers. Apple began transitioning from Intel processors to its own Apple Silicon (ARM architecture) chips in 2020, and since 2023 every new Mac sold ships with these chips (M1, M2, M3, M4); macOS Tahoe (macOS 26, released September 15, 2025) is listed by Apple as the last major version to still support Intel Macs. For compatibility with older apps, macOS includes Rosetta, a translation layer that lets programs compiled for Intel run on Macs with Apple Silicon chips.

Real-world example: a family that buys a new laptop in 2026 purely for browsing, video calls and online banking probably won’t notice much difference between Windows and macOS, since in both cases the license is already baked into the hardware price. Someone who instead wants to keep an old laptop without a TPM 2.0 chip alive — which, under the official Microsoft requirements, would block a Windows 11 install — often finds a free way to extend its life with a lightweight Linux distribution.

Linux, like Windows, isn’t tied to a single manufacturer: it runs on x86-64-compatible PCs of any brand, plus a vastly wider range of devices, from small single-board computers to servers. It’s the same principle of hardware openness that has run through much of the history of computers: the more a system is decoupled from a single manufacturer, the wider the variety of machines it can run on.

Security and updates

Each of the three systems approaches security differently, and none of the three approaches eliminates every risk on its own. Windows 11 leans on a sturdier hardware baseline, requiring Secure Boot and TPM 2.0 from the moment of installation; some protection features, like BitLocker to Go, are reserved for the Pro edition and above and are missing from Home. macOS benefits from a much more uniform pool of hardware, entirely controlled by Apple, but that doesn’t make it immune to malware or phishing by definition. Linux, thanks to its open source code under the GPL license, lets anyone examine it and fix flaws; LTS distributions like Ubuntu add a predictable security maintenance cycle on top of that: 5 years of free updates for every LTS release, published every two years, extendable up to 10 years (15 with the Legacy add-on) through an Ubuntu Pro subscription, free for up to 5 machines for personal use.

The release rhythm also reflects a different philosophy: besides LTS releases, Ubuntu ships an “interim” version every six months, each with 9 months of updates — a pace built for people who want to try new features often, while those who prefer stability stick with LTS. Developers, whatever system they work in, often reach for tools built specifically to look under the hood, like the developer options found on mobile operating systems too.

Available software and use cases

On the adoption front, the numbers tell very different stories depending on the arena. On the desktop, worldwide, Windows remains the most widely used system with 56.55% share according to StatCounter Global Stats as of June 2026 (a tracked web-traffic figure, not a direct count of installations, but still the first reading in years to put Windows below 60%); macOS and OS X combined sit around 16.37%, Linux at 4.39%. Among Steam gamers the gap is even wider: Windows at 93.47% in April 2026, Linux at 4.52% (after briefly touching nearly 5% the month before, partly driven by the end of support for Windows 10 pushing some users toward Linux-based options like SteamOS), macOS at 2.01%.

On web servers, the picture flips almost completely: according to W3Techs, as of September 6, 2026, Linux runs 62.2% of websites with an identifiable operating system, and the combined Unix and Unix-like family covers over 90% of recognizable web servers, against roughly 8% for Windows Server. The operating system on your own desktop is often the exact opposite of the one running the sites you visit every day. For anyone whose only concern is keeping their own computer tidy, regardless of the system chosen, clearing out leftover space and files remains basic maintenance, as covered for PCs and Macs.

	Hardware	Security	Typical use
Windows	Any compatible PC, with minimum requirements (TPM 2.0, UEFI Secure Boot)	Secure Boot and TPM built in; some features Pro-only	Consumer desktop, office, gaming
macOS	Mac only (Apple Silicon since 2023)	Uniform hardware, controlled by Apple	Consumer desktop, creative work
Linux	Any-brand x86-64 PCs, servers, embedded devices	Open source under GPL, LTS cycles with multi-year updates	Servers and hosting, development, growing in gaming

There’s no operating system that’s objectively best in every case: people after the widest range of consumer software and the broadest compatibility with peripherals tend to stick with Windows; people working within the Apple ecosystem, or who prefer hardware and software designed together by the same company, choose macOS; people running servers, developing software or wanting to customize every detail of their system, often without spending anything on licenses, gravitate toward a Linux distribution. These are three different philosophies more than three simply interchangeable alternatives.
