Registered Mac developers and those with early access to Yosemite via Apple's new public beta program can try out the HTML5-based feature simply by logging in to their Netflix account. Viewers were previously required to use plugins like Microsoft's Silverlight for a number of reasons, including digital rights management and adaptive streaming.
"Congratulations to the Apple team for advancing premium video on the web with Yosemite! We're looking forward to the Yosemite launch this Fall," Netflix engineering executives Anthony Park and Mark Watson wrote in a blog post announcing the move.
The new streaming options are made possible thanks to the adoption of a number of new web standards in the upcoming Safari release.
Encrypted Media Extensions and WebCrypto, meanwhile, address concerns about digital rights management. They allow end-to-end encryption of the media stream between the browser and Netflix's servers to prevent users from simply capturing video as it comes in.
