References to a new 4K 21.5-inch iMac and a multi-touch Bluetooth remote (possibly for the a new Apple TV), may have been spotted in the second beta of OS X El Capitan by Pierre Dandumont.
Dandumont first noticed a reference to a Retina display panel with a 4096×2304 resolution. The 5K 27-inch iMac features a resolution of 5120×2880 and the lower 4K resolution would be a perfect match for Apple’s smaller 21.5-inch iMac.
In addition, he spotted references to Intel’s new Iris Pro 6200 graphics.
The second is a series of new reference graphics cards. First, Iris Pro Intel Graphics 6200 GPU for CPU Broadwell recently announced. A GPU perfect for 21-inch iMac entry. The second reference, it is the AMD Radeon R9 M380, M390, M395 and M395X. Nothing new under the sun, they are simply R9 M2xx (already used in the iMac ) renamed with a possible slight increase in the frequency.
It’s unclear if the AMD graphics are upgrade options or for different Mac models.
Dandumont also spotted references to an Apple Bluetooth Remote which could be part of the much rumored Apple TV update.
There are references to the audio, buttons, touch, sensors, management of proximity and infrared, we can assume that the remote work in part with older systems. The pilot gives consistent values for an Apple product (Vendor ID 76 / 0x4C , Product ID 614 / 0x266 ). No reference to the web, anywhere, I’m obviously the first to find it.
