This beta of OS X 10.10.3 contains new developer APIs that work with the Force Touch trackpad in the new MacBook Pro (Retina, 13-inch, Early 2015) to allow a new level of interactivity and control within your apps.

● Force click. Apps can have any button, control, or region on the screen respond to a press of stronger pressure. This Force click can provide a shortcut to additional functionality within the app.

● Accelerators. Pressure sensitivity in the trackpad enables apps to give users greater control. For instance the fast-forward button in media playback can speed up as pressure increases.

● Pressure sensitivity. Drawing and other creative apps can take advantage of the pressure-sensing capabilities of the trackpad to make lines thicker or give the brush a changing style.


● Drag and Drop. Apps can add the springLoaded property to their controls so they can react to a Force click gesture while in the middle of performing a drag, for instance to immediately open a new target for the drop.

Previous betas introduced the new Photos app for OS X and diverse emojis.
