Why usage of OS X Yosemite beta is nearly 4x that of Mavericks last year



The developer preview of OS X Yosemite is already seeing rapid adoption numbers, and it isn’t even officially available yet.

According to new research, Yosemite accounted for 0.2% of OS X ad impressions in North America between the dates of June 2nd and July 2nd. That’s nearly four times the number of Macs running the developer preview of OS X Mavericks this time last year.

Why the big spike in usage? The answer is actually simple.

“In the three days following the release of the first OS X Yosemite Developer Preview, adoption jumped significantly – hitting 0.15% of total U.S. and Canadian Mac OS X Web traffic,” according to Chitika. “That figure is particularly impressive considering that adoption of the OS X Mavericks Developer Preview achieved only a 0.05% share after 30 days. The increased level of aggregate activity for Yosemite is likely partially driven by the prominent changes present in this OS version fueling a higher degree of developer curiosity and experimentation.”


More importantly, Apple isn’t limiting who can test Yosemite to just registered Mac developers this year. Anyone can sign up to help test Yosemite through Apple’s OS X Beta Program.

All you need to give Apple is your Apple ID, and you’ll get sent a redemption code that will let you download the latest Yosemite preview through the Mac App Store.

You have to sign an agreement with Apple before joining the program, because Yosemite is in beta and not intended for normal use like Mavericks. Apple doesn’t want you to be mad if apps don’t work and things randomly crash, because that’s the price you pay for testing software that’s unfinished.

The third developer preview of Yosemite came out just yesterday, and Apple still has several updates to go before it will be ready for public download in the fall.

Chitika also has an interesting graph on the different versions of OS X in use right now. Mavericks is of course leading the race with nearly half of North American adoption.

    When it comes to Yosemite DP3, yes it is stable but not stable enough. Adobe Flash Player is buggy (YouTube), Face Time bugs out when you try to call via Audio, Safari is a lot more buggier (to the point where I got over to Chrome until DP4), Notification Center has actually more lag than it had on DP2.

    With that said, yes it is stable but if you install it, don’t expect everything to work as it should. I see people complain about how not everything has a new UI and has bugs.. Of course it does, it’s not even meant for general usage. Leave the Developer Preview for developers.

    Developer Preview is kind-of like Alpha stage. Since they have made the base and general functionality for the OS, but the rest needs to be tested with developers as well to make it even better.

    When it enters Beta (Public beta this time) that means they have made it stable enough for their consumers to install it and trust their personal Mac and important stuff on the new OS. It also means all the functionality that they promised on WWDC works and is included but could still have minor bugs.

    All my years using Mac, I have never seen such demand for an OS X update. It’s embarrassing.
