Apple on Thursday released the first public beta of its next update for macOS Sierra 10.12.5, a minor update largely anticipated to focus on bug fixes and speed improvements.
The new software is available to anyone registered with Apple's Beta Software Program. Signing up is free, and grants access to future public betas of both macOS and iOS.
The latest 10.12.5 beta follows an initial developer release on Tuesday. Apple simultaneously posted the first developer seeds of iOS 10.3.2, watchOS 3.2.2, and tvOS 10.2.1.
It's not clear what changes are in macOS 10.12.5, since Apple hasn't included any release notes, though no major changes or feature additions have been discovered in testing. Typically that means an update is maintenance-oriented.
The finished version of macOS 10.12.4 was released on Monday and brought minor enhancements, like Night Shift for the Mac, new PDFKit APIs, cricket results in Siri, and more options for iCloud Analytics.
