Fresh data gathered by ad network, Chitika, shows Macs running Apple’s OS X 10.10 Yosemite beta accounted for 0.2% of all OS X-based ad impressions in North America one month after release. This is nearly four times that of its predecessor OS X 10.9 Mavericks.

As seen in the chart, Macs that are running the first OS X Yosemite Developer Preview accounted for 0.15% of all US and Canadian OS X Web traffic just three days after the beta build’s release on June 2. That figure jumped to 0.2% after a full 30 days in the wild. By contrast, Apple’s Mavericks preview only managed to accumulate a 0.05% share of Web traffic after 30 days.

The research firm believes Yosemite’s long list of new features, continuity with iOS devices and a new iOS-inspired design fueled faster adoption. In particular, Safari feature additions and integration with Spotlight search could have fueled higher Web usage. Another possibility is Apple’s OS X Beta Program, which lets members of the public join developers in testing pre-release builds of the next-gen operating system.

Chitika notes that the second bump in adoption started from day 15, which was likely a result of Apple’s second Developer Preview release, which brought a number of bug fixes to the operating system’s so-called “continuity features.” A third beta was recently issued but falls outside of the study’s purview.

The cause of Yosemite’s third rise in share seen toward the end of June is a little less clear, though the date corresponds with Apple’s announcement that it will be halting development of Aperture and iPhoto, effectively retiring the first-party photo editing software. The company plans to combine features from Aperture and iPhoto into a new “prosumer” title called OS X Photos, though the app won’t be available until 2015.
