> Mac shipments are estimated to have grown from 1.7M in the first quarter of 2023 to 2.1M in the same quarter this year. That represents year-on-year growth of 22%, giving Apple a 14.2% share of the US PC market.

Author does not understand what market share means



2.1M/14.8M = 14.2% marketshare. Marketshare is the percentage of new shipments, which is the way its always been measured for this space and others (such as smartphones), the author got it right.


And… where is 14.2M coming from and where is 22% market share growth coming from?

Seems awfully likely they conflated 22% sales growth with market share growth


I typo'd the number - it was 14.8M. But per the article it came from a company called Canalys.


What do you propose to measure it more accurately?

Should we add questions about computer OS usage to the US Census?


I propose recognizing that 22% greater sales does not mean 22% greater market share
