> 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.
I haven’t yet seen macOS 26 but iOS 26 is ugly and the least usable phone OS I’ve ever used - controls (theirs placement) and blurry areas waste too much space, animations are distracting and “reduce motion” option just reduces them with flickering which even worse. I was a happy iPhone users for 5+ years and was considering to buy a MacBook (as a replacement for an old Thinkpad) but iOS 26 is such abomination that I will wait and if the next version will not remove Liquid Glass I’ll buy an Android phone and a Linux-compatible notebook.
