While the latest MacBook Pro with Touch Bar notebooks launched under four months ago, references to possible next-generation models have already been discovered in the latest macOS 10.12.4 beta.
Apple blog Pike’s Universum uncovered a trio of motherboard identifiers that do not correspond with any current MacBook Pro model, but use the exact same processor power management data as 13-inch and 15-inch MacBook Pro models released in late 2016. The plist files do not exist in previous macOS Sierra versions.
The next-generation MacBook Pro models would likely be powered by Intel’s faster Kaby Lake processors, which are the natural successor to Skylake processors used in late 2016 models. This would be in line with a report from six weeks ago claiming the MacBook Pro will receive only minor bumps in processing power for 2017.
Mac-B4831CEBD52A0C4C would likely be for two new 13-inch MacBook Pro models with function keys. The models would likely have Kaby Lake processors with a maximum Turbo Boost of 3400 MHz and 4000 MHz respectively.
