Apple Inc. appears to be pretty fast when it comes to updating and improving its macOS Sierra operating system. Just two days after rolling out its first macOS 10.12.2 beta to developers, the Cupertino-based tech company is now unleashing the second beta build of the upcoming software update.

This new build is just a minor additional update, even so, it does come along with several bug fixes. The bugs that this new macOS 10.12.2 beta is capable of crushing are still unknown at the moment, according to Apple Insider.

At this point, what is known about the new macOS Sierra 10.12.2 beta is, it comes with the same emojis that are present in the recently released iOS 10.2 beta. It can be noted that when iOS 10.2 beta was uncovered, reports claimed that it came with Unicode 9 characters.

Some of the emojis found in the betas include selfie, face palm, croissant, crossed fingers, shark, avocado, and owl, among many others. It has been indicated that the existing emojis in the macOS Sierra 10.12.2 and iOS 10.2 beta updates are enhanced with more details for a more realistic look, MacRumors reported.

Furthermore, the new beta build is 16C32f, while the previous beta is 16C32e. The new build code could not be considered as a full second beta build, this can spell out that the new beta is still labeled as macOS Sierra 10.12.2 Beta 1, rather than Beta 2.

Nevertheless, the new beta is slated to provide under the hood fixes, as well as performance improvements. The new beta is already up for grabs for download over-the-air for registered developers who are obtaining the macOS Sierra 10.12.2 beta for the first time. However, the macOS Sierra update is not being rolled out through the Mac App Store.

That being said, the previous macOS 10.12.1 update was released on Oct. 24.
