With Apple’s media event just a few hours away, MacStories is reporting that the OS X UI is up for some modifications, namely the introduction of iOS style scroll bars and behavior.
According to our source, iOS influence is visible in the new OS user interface, but it’s still very much Aqua-based. Apple took some elements from iOS and applied them to OS X, trying to blend everything nicely.
The first big news is iOS scroll bars and scrolling behavior are coming to OS X. That means you’ll have to say goodbye to the current Aqua scroll bars and get ready for a more minimal look. Also, the “rubber band” elastic scrolling iOS is famous for is making its first appearance on the desktop, and we’re told it “works really well and feels natural”. Basically, it works like the current inertial scrolling, but when you hit the top or bottom of a scroll view it “rubber bands” down like iOS devices do. Stuff like “pull to refresh” will be possible (and most of all, it’ll feel native) on OS X. We don’t know whether this would be an option or if Apple will turn on the new scrolling by default.
