From a purely Kodi/media playback standpoint, there's no advantage to the Core i3/i7 models over the Celeron model (outside of non-GPU decoded formats, like Hi-10P and HEVC); dual channel memory (2 identical capacity modules) can provide a decent performance boost in some situations but certainly not needed for a standard Open ELEC/Libre ELEC/Kodi setup.
All Haswell model Chromeboxes are fully supported by the Chrome Box Kodi E-Z Setup Script.
Apple has released OS X El Capitan 10.11.5 for Mac users, the update includes bug fixes and improvements to the Mac operating system and is recommended for all users running a prior version of El Capitan.
The short notes attached to the 10.11.5 download suggest the update improves security, performance, and stability of the Mac operating system.
4K (2160p) output is limited to 30Hz via both the Display Port and HDMI 1.4a outputs.
H.265/HEVC is software (CPU) decoded, so playback is limited to 1080p max and low/moderate bit-rates.
It's not recommended for Kodi use due to the limitations of the integrated GPU (24p bug, no advanced deinterlacing), and the availability of the significantly more capable Haswell/Broadwell-based boxes, usually at a lower cost.
It's also not capable of dual-booting Chrome OS Kodi, due to lack of Legacy Boot mode in the stock firmware.
Although Kodi does not run natively under Chrome OS, the Chromebox can easily be made to run Linux (or Windows) and Kodi.Device pages are made when there's a bunch of useful information for a particular device, and someone takes the time to make that page.Keep in mind, some devices simply don't need a page of specific information, but are still excellent devices.Samsung first introduced the ability to unlock its Windows 10-powered Galaxy Tab Pro S with a Samsung Flow app for Android last year, and this expansion means any Windows 10 PC is now supported.Alongside the fingerprint support, Samsung is also enabling the ability to sync smartphone notifications to your PC.
