Windows vs Mac Market Share: Global & U.S. Desktop Statistics
Windows vs Mac market share depends on how you measure the market. For desktop web usage, Windows remains the largest operating-system family worldwide, while Apple’s Mac operating systems represent a significant minority. However, desktop web traffic, PC shipments, and the number of computers in use are different measurements and should not be treated as the same thing.
According to the latest completed StatCounter desktop data for August 2026, Windows accounted for 62.67% of worldwide desktop operating-system activity. StatCounter listed Apple’s platforms separately as macOS at 15.31% and OS X at 11.60%. Combined, the two Apple categories represented 26.91%.
Windows vs Mac Market Share: Quick Answer
The latest worldwide desktop web-usage snapshot shows:
| Desktop operating system | August 2026 share |
|---|---|
| Windows | 62.67% |
| Mac — macOS + OS X | 26.91% |
| Linux | 8.88% |
| Chrome OS | 1.53% |
So, using the latest StatCounter categories, Windows has a substantially larger worldwide desktop web-usage share than Apple’s Mac operating systems. The combined Apple figure is calculated by adding the separate OS X and macOS categories reported by StatCounter.
A useful way to express the relationship is that Apple’s combined desktop share is about 43 Mac page views for every 100 Windows page views in this particular worldwide dataset.
Why Is Mac Listed as Both macOS and OS X?
This is one of the most important details when researching the keyword “Windows vs Mac market share.”
StatCounter currently displays OS X and macOS as separate categories in its desktop operating-system statistics. Looking at only the macOS row can therefore dramatically understate Apple’s overall desktop presence.
For a Windows-versus-Mac comparison, the two Apple categories should be treated as an Apple desktop family rather than assuming the macOS row alone represents every Mac.
That is why the August 2026 numbers should be read as:
Windows: 62.67%
Apple/Mac family: 15.31% + 11.60% = 26.91%
The underlying StatCounter table still shows the two Apple categories separately, so both figures should be preserved when citing the original data.
How Does StatCounter Measure Market Share?
StatCounter’s figures are based on page views, rather than a direct census of computers.
The company says its Global Stats data is based on more than 3 billion page views per month across more than 1 million websites. Because the measurement tracks web activity, it is better described as desktop web usage share rather than the exact percentage of all computers running each operating system.
This distinction matters.
A person who spends many hours browsing the web can generate substantially more page views than someone who rarely uses a browser. A web-usage statistic therefore cannot automatically be converted into “62.67% of all computers are Windows.”
Windows vs Mac Market Share in the United States
The United States has a different desktop operating-system distribution from the worldwide market.
StatCounter’s August 2026 U.S. desktop figures were:
| Operating system | U.S. desktop share |
|---|---|
| Windows | 53.25% |
| OS X | 17.60% |
| macOS | 8.04% |
| Linux | 18.19% |
| Chrome OS | 2.92% |
Combining the two Apple categories gives 25.64% for the Mac family in the U.S. desktop snapshot.
This demonstrates why geography matters when evaluating Windows vs Mac market share. A website or software company with mostly U.S. desktop visitors may see a substantially different Windows-to-Mac mix from a company serving the worldwide market.
Windows vs Mac Market Share in Europe
Europe also has a stronger Apple desktop presence than the worldwide Windows figure alone might suggest.
For August 2026, StatCounter reported 68.52% Windows, 12.92% OS X, and 10.18% macOS for European desktop operating systems. Combined Apple share was therefore about 23.10%.
| Region | Windows | Apple/Mac combined |
|---|---|---|
| Worldwide | 62.67% | 26.91% |
| United States | 53.25% | 25.64% |
| Europe | 68.52% | 23.10% |
These figures illustrate why a single global number does not describe every market equally.
Windows vs Mac Market Share Is Not the Same as PC Sales
Another common mistake is comparing operating-system web usage with PC shipment market share.
PC shipment data measures new computers shipped during a particular period, not every computer currently in use and not web traffic.
For example, Gartner reported that Apple had 10.6% of worldwide PC shipments in Q1 2026, while Omdia reported Apple at approximately 11.1% in Q2 2026 based on 7.3 million shipments out of a 65.7 million-unit market. IDC’s Q2 2026 data put Apple at 9.9%.
That does not contradict the desktop web-usage figures.
The measurements answer different questions:
| Metric | What it measures |
|---|---|
| StatCounter OS share | Desktop web activity |
| PC shipment share | New PCs shipped |
| Installed base | Computers currently in use |
| Enterprise share | Business/organization deployments |
| Gaming share | Computers participating in a gaming ecosystem |
So there is no single percentage that can accurately answer every version of “Windows vs Mac market share.”
What About Windows 11 Market Share?
Windows itself is also divided into multiple versions.
StatCounter’s worldwide desktop Windows data for August 2026 reported:
| Windows version | Share of Windows desktop traffic |
|---|---|
| Windows 11 | 68.60% |
| Windows 10 | 30.14% |
| Windows 7 | 0.96% |
| Windows XP | 0.14% |
| Windows 8.1 | 0.11% |
Windows 10 reached its official end of support on October 14, 2025. Microsoft states that regular security updates and technical support ended on that date, although eligible systems can use Extended Security Updates under Microsoft’s applicable programs.
This creates an important distinction between Windows market share and supported Windows market share.
Why Windows Still Has a Large Desktop Presence
Windows is available across a very broad PC hardware ecosystem, with machines from numerous manufacturers and at many price points.
That differs from Apple’s Mac model, where Apple controls both the hardware and operating-system platform.
This hardware-distribution difference is one reason Windows can maintain a large desktop footprint across consumer, business, education, gaming and other segments.
The PC shipment data reinforces the scale of the overall PC market: Omdia estimated 65.7 million PC shipments worldwide in Q2 2026, including desktops, notebooks and workstations.
Why Mac Market Share Matters Even Though Windows Is Larger
A smaller overall market share does not mean Mac traffic is unimportant.
For software developers, publishers, web developers and SaaS companies, the relevant question is often:
“What percentage of my target audience uses a Mac?”
A business with a U.S.-heavy audience, design-focused customers, professional users or other specific segments may have a much larger Mac audience than the worldwide desktop average suggests.
This is why market-share research should ideally combine the global number with country, audience and use-case data.
Is Windows or Mac More Popular for Gaming?
Gaming is a separate market and should not be assumed to match general desktop usage.
Gaming platforms can have very different operating-system distributions because software compatibility, graphics drivers, anti-cheat systems and game availability influence what operating systems gamers use.
For this reason, a website researching “Windows vs Mac market share” should avoid using general desktop statistics as if they were automatically gaming-market statistics.
Has Mac Market Share Replaced Windows?
No single market-share dataset supports the idea that Mac has replaced Windows as the dominant worldwide desktop operating system.
The latest StatCounter worldwide desktop snapshot still places Windows ahead of the combined Apple categories. At the same time, Apple’s share is large enough that Mac compatibility remains commercially significant, particularly in markets where Apple has stronger adoption.
The most accurate conclusion is therefore:
Windows remains the larger worldwide desktop platform, while Mac represents a substantial secondary desktop ecosystem whose importance varies by country, industry and audience.
Windows vs Mac Market Share: What Businesses Should Use
Businesses should not choose a platform based only on the worldwide market-share percentage.
For websites and web applications, the safest approach is to support both Windows and Mac browsers.
For desktop software, the decision should consider:
- Target-country traffic
- Customer demographics
- Enterprise versus consumer audience
- Developer and professional workflows
- Gaming requirements
- Hardware compatibility
- Required applications and integrations
A global statistic is useful for market sizing, but your own analytics can be much more valuable for product decisions.
Frequently Asked Questions
For August 2026 desktop web usage, StatCounter reported Windows at 62.67%. Apple’s desktop categories were 15.31% macOS and 11.60% OS X, giving a combined Apple/Mac figure of 26.91%.
In StatCounter’s August 2026 U.S. desktop data, OS X accounted for 17.60% and macOS for 8.04%. Combined, Apple’s desktop categories represented approximately 25.64%.
Windows has a larger worldwide desktop web-usage share than the combined Apple desktop categories in the latest StatCounter snapshot. However, StatCounter measures page views rather than directly counting individual computer users.
“Mac market share” normally refers to Apple’s Mac computer ecosystem, while “macOS market share” refers specifically to Apple’s operating system. In StatCounter’s current reporting, Apple desktop traffic is split between OS X and macOS, so using only the macOS figure can undercount Apple’s desktop presence.
Windows is more common in worldwide desktop web activity according to the latest StatCounter data. Apple’s Mac operating systems make up a substantial minority of desktop web activity, but Windows remains ahead globally.
No. PC shipment share measures computers shipped during a specific period, while operating-system market-share datasets such as StatCounter measure web activity. The two numbers can be very different without either measurement being incorrect.
Bottom Line
The phrase “Windows vs Mac market share” does not have one universal percentage.
For the latest completed StatCounter worldwide desktop snapshot, Windows represents 62.67% of desktop web activity, while Apple’s macOS + OS X categories total 26.91%.
For a meaningful comparison, always identify the measurement first: desktop web usage, PC shipments, installed base, enterprise deployments or gaming usage. Those measurements describe different parts of the computing market, and combining them can produce misleading conclusions.
For anyone researching desktop audiences, the clearest takeaway is simple: Windows has the larger worldwide desktop footprint, but Mac represents a significant audience that can be much more prominent in specific countries and user segments.
