macOS Versions Market Share in 2026

This chart shows the top 10 macOS Versions for each week in the last year. Values are percentages.

Some interesting observations are:

• As there has been a significant growth of our dataset some part of volatility and spikes in the data may be caused by our increasing dataset rather than by a general trend. Results appear to be stabilizing though.
• macOS 26.5 appeared among the 10 most used versions during May and was clearly the most used version with up to around 74% during July. In the last week of July, the share started decreasing and was at 10.84% as of the end of October.
• macOS 26.6 was among the most used versions for the first time in the last week of July and at the beginning of September had a share of around 62%. At the end of the October, it had dropped to 21.30% while macOS 26.7 had the highest share with 30.82%.
• macOS 27.0 increased over 10% within a short time after the official launch of macOS 27. In October the rise wasn't as steep anymore. The share of macOS 27.0 was at 16.63% at the end of the month while macOS 27.2 seems to be appearing considerably already at 7.71%.
