This chart shows the top 10 macOS Versions for each week in the last year. Values are percentages.
macOS Versions by week
Some interesting observations are:
- macOS 15.6 had a share of about 63% as of end of August 2025. The share has since declined to 15.25% at the end of November.
- macOS 15.7 appeared in the middle of September for the first time in the most used versions and was at 23.62% at the end of November.
- The share of macOS 26.0 has been volatile. It was at over 47% during October and has since then declined to 5.21% as of end of November. As there has been a significant growth of our dataset over the last months volatility like that may be caused by our increasing data rather than by a general trend.
- The share of macOS 26.1 has increased considerably in November and was at 43.21% at the end of the month.
