Cloudflare stats also seem to support peaks of 15% usage but around 9-10% on average. In the United States alone, the market share for Linux is nearly 12% now for the whole month and Cloudflare stats suggest peaks of up to 25% (!) Linux desktop usage on certain days and times.


The trendline suggests this is just the start. When will companies realize they cannot ignore Linux anymore?


The OS was renamed at some point; the first versions of the Unix/NEXTstep-based OS made by Apple were named Mac OS X, then at some point they switched to “OS X” (which hardly anyone ever actually said), then at some point to “macOS”. So it’s somewhat silly that they are separate lines and I don’t know what the difference is on that graph.
I thought the X was in reference to the roman numeral for 10. Mac OS X == Mac OS 10. They sat on version 10 for a long time and then moved on so it’s no longer X.
Yes, this is true (although the name change happened years before the major version was no longer 10) and doesn’t contradict anything I wrote. But the first version of Mac OS X was an entirely new OS technologically unrelated to Mac OS 9; not the case for later version jumps.
so is macos people running the apple chips and osx is people still running x86/64?
In general no, at least according to https://en.wikipedia.org/wiki/MacOS#macOS the name change happened several years before the architecture change. But I don’t know what the distinction is on that graph; it’s possible it just depends on how the OS is called in the user agent string?
