Just a week after launching macOS Sierra 10.12.2 beta 1, Apple is now rolling out the second beta version of the upcoming update to developers. Registered developers can now download the second beta build that is expected to address certain issues found in the first beta build and the official macOS Sierra 10.12.1.

According to Cult of Mac, the new beta build has fixes for bugs that Apple developers have identified since the new Mac OS was released to the public back in September. The new beta is also said to bring performance enhancements to make the user experience of macOS Sierra more seamless.

Registered developers can readily download the new software from Apple’s Developer Center. For those who already have the previous beta installed on their Mac device, they can grab beta 2 directly from the Mac App Store via the software update mechanism.

The new macOS Sierra 10.12.2 beta is unlikely to come with new features, since the first beta already introduced them when it was launched to developers and public beta testers. As per MacRumors, what users can expect from the upcoming update based on the first beta is the new set of Unicode 9-based emojis.

Apart from the new characters like clown face, face palm, drooling face and fox face, among many others, Apple has also reportedly enhanced the artwork of existing emojis to make them appear more detailed and realistic than the very cartoonish appearance they currently have with macOS Sierra 10.12.1.

The same set of emojis has been confirmed to roll out to the iPhones and iPads via the upcoming iOS 10.2 software update. As previously reported, iOS 10.2 is bringing new Music sorting options and Star Ratings to the Music app. There will also be improvements in the Camera app and Siri, as well as a new widget for the Videos app and a different headphone icon for the status bar.
