macOS Sierra 10.12.1 Beta 3 For Macs Released

Apple has just seeded macOS Sierra 10.12.1 beta 3 one week after releasing beta 2 build, and about two weeks after seeding the first beta build to both developers and testers.

Like previous versions of macOS Sierra 10.12.1, this latest pre-release seed seems to continue to put focus on fixing any known issues within the platform that have been reported directly to Apple from those already consuming the platform. That means that there are currently no outward-facing changes for users to interact with, or indeed any feature inclusions or functionality improvements for users to find.


With this release, Apple is mainly continuing to fix bugs and ensure that the platform is as stable as possible for all Mac owners who opt to interact with the operating system.

One small feature improvement within macOS Sierra 10.12.1 can be found in the native Photos application, with added support for photographs captured from an iPhone 7 Plus using the new Portrait mode in the iOS 10.1 beta. This feature in iOS 10.1 allows device owners to capture photographs with depth-of-field effects applied. macOS Sierra 10.12.1 beta 1 introduced support for those images within macOS, with the second and third betas continuing to offer that support. Of course, if any additional features do come to light, then we will be sure to bring them to you with immediate effect.

With the public release of macOS Sierra, Apple introduced a number of appealing features for those with a compatible Mac. Integrations like Auto-Unlock, Universal Clipboard, and tab support for all apps, as well as the first appearance of Siri, means that macOS Sierra should be seen as the most advanced version of macOS to date. Apple is clearly looking to ensure that the platform is held in that regard with the continual release of updates.

As is always the case, this third pre-release seed of macOS Sierra 10.12.1 can be downloaded as an over-the-air (OTA) update via the Mac App Store for any registered developer who already has a previous beta seed of macOS Sierra 10.12.1 installed. Alternatively, interested developers with the necessary Apple Developer Program privileges can grab the latest installation file directly from the developer portal.
