- Within three days, OS X 10.10 represented 0.15% of U.S. and Canadian web traffic. It took OS X 10.9 Mavericks a month to reach 0.05%.
- Within a month, Yosemite developers were generating 0.2% of North American Mac OS X traffic — nearly four times the share Mavericks developers generated last year in the same time frame.
