Apple Seeds 5th Beta macOS Sierra 10.12.1
Developers and public beta testers got new bits to play with…
macOS Sierra is one of the biggest updates to Apple’s desktop operating system, likely since the implementation of OS X. Or at least, it will be once the (big) bugs are gone and the new Apple File System gets implemented.
On 2016-10-19, Apple seeded the fifth beta of macOS Sierra 10.12.11 to both developers and public beta testers. Developers can get it from the Apple Developer Center and both developers and public testers can get the bits through the Software Update mechanism in the Mac App Store.
Version 10.12.1 is a bug fix release that smooths out performance hiccups and addresses other issues that have been reported since the operating systems initial release just a short time ago. The release doesn’t provide much in the “new features” department, however. Though support for Apple’s iPhone 7/ 7 Plus’ Portrait Mode, being introduced with iOS 10.1, is included in the desktop OS’ Photos app.
Other than that, I wouldn’t expect too much more.
