OS X Yosemite has had a successful launch in the US

  OS X Yosemite was released by Apple just over a week ago, and an American Mac user analysis company tells us that its adoption rate is slightly higher than that of OS X Mavericks. In the image above you can see the difference between the adoption rates of the two versions of Apple's operating systems, with OS X Yosemite having a very, very small lead over OS X Mavericks, but we're talking about comparative adoption rates for the previous week launch.

  Because we are talking about an adoption rate that was calculated for North America only, so the global adoption rate is most likely different, considering that this data cannot always be applied to users worldwide.
