Latest OS X El Capitan beta build hints at 4K 21.5-inch Mac, Bluetooth remote for possible new Apple TV

It’s the beta builds that sometimes show the cool stuff that’s coming down the road.

The newest developer build of OS X El Capitan has revealed hints of a 4K 21.5-inch iMac as well as a Bluetooth remote control for the Apple TV.

The beta references Mac support for a new 4096 x 2304 resolution Apple-made display panel. While the larger, more expensive 27-inch iMac is offered with a 5K display, it could make sense for the smaller screen to be upgraded to a 4K resolution.

The beta also references a new Intel graphics chipset known as the Iris Pro 6200. This new, Broadwell-integrated graphics processor launched earlier this month, which would be a natural fit for powering a 4K iMac.

References to four new AMD Radeon R9 processors (M380, M390, M395 and M395X) are also found in the beta, which could indicate additional Mac models or 4K iMac upgrade options.

The beta’s references to a new Bluetooth remote control include hints as to infrared sensor as well as Multi-Touch trackpad with inertial scrolling support. There is also a reference to what could be Force Touch support, though this seems less certain. The device also appears to support audio, which could indicate either playback or input for Siri. This file does not exist in earlier, public versions of OS X, nor the OS X 10.10.4 Yosemite release that is also in beta.

An updated Bluetooth remote control could indicate that Apple is getting closer to completing its next-gen Apple TV set top device.

Stay tuned for additional details as they become available.
