A developer-only preview of what would become the macOS Sierra 10.12.4 software update references a total of eight next-generation MacBook Pro models with the latest Kaby Lake processors from Intel. First discovered by the Apple-centric blog named Pike’s Universum, the code strings in question point to unused IDs for three motherboard identifiers. Aside from other improvements, the Kaby Lake platform enables lower power consumption while possibly bringing support for 32GB RAM.
macOS Sierra 10.12.4 beta 1
Yesterday's beta release of what would become the fourth major software update to macOS Sierra doesn't just bring iOS's Night Shift mode to your Mac. Aside from that feature and things like an updated PDF API, expanded Dictation support or the ability for Siri to look up cricket scores and rosters, macOS Sierra 10.12.4 includes better handling of Windows executable files in the Finder.
As discovered by Microsoft's Mac product designer Vaclav Vancura, rather than use a generic icon to represent Windows executables like before, macOS Sierra 10.12.4 now actually parses .EXE files for native Windows resources such as icons.
Following yesterday's release of developer-only previews of the upcoming iOS 10.3 and macOS Sierra 10.12.4 software updates, Apple today made the new betas available to public beta testers who are enrolled in Apple Beta Software Program.
iOS 10.3 public beta can be installed via the Software Update mechanism on iOS devices with an appropriate configuration profile installed. macOS Sierra 10.12.4 public beta can be downloaded on your Mac through Mac App Store's Updates tab.
Aside from seeding iOS 10.3 beta 1 to its registered developers, Apple also released the first developer-only beta of what would become the fourth major software update to macOS Sierra. macOS Sierra 10.12.4 beta 1 enhances your Mac with Night Shift mode and other improvements and new features.
