macOS 26.0 is continuing to appear more often with 28.61% as of end of September 2025. In our dataset, it had a spike to almost 40% in the middle of September, but came back a bit after that.
Compare to macOS 15 which exactly one year ago had 50% of the market share.
Obviously, it is just a subset. But the drop from 40 to 30% is pretty significant even for that subset. (Based on https://telemetrydeck.com/platforms/swift/ - 6,280 apps use it, but that includes macOS and iOS apps)
PS. I am a macOS indie app developer, but I personally do not use TelemetryDeck and I am not in any way related to them. Just found this data being really interesting, so decided to share.
