Apple released on Monday the second beta of the upcoming macOS High Sierra 10.13.3 software update for supported Mac computers. The update was made available for registered developers through the Apple Developer website.

Tagged as build 17D25b, the macOS High Sierra 10.13.3 beta 2 release comes one week after the first beta release and it's now available for macOS application developers with a paid and active Apple Developer account, and it's been released along with the macOS 10.13.3 SDK, allowing them to develop apps for Macs running macOS High Sierra 10.13.3.

Developers interested in running the latest macOS High Sierra 10.13.3 beta need to download the macOS Developer Beta Access Utility from their Apple Developer account, under the Downloads section. Those who already have the first macOS 10.13.3 beta installed will be able to update to beta 2 from the Updates pane in the Mac App Store.

iMac Pro 2017 now supported

The updated release notes of macOS 10.13.3 beta 2 shows that the operating system supports MacBook Late 2009 or newer, MacBook Air Late 2010 or newer, MacBook Pro Mid 2010 or newer, Mac mini Mid 2010 or newer, iMac Late 2010 or newer, Mac Pro Mid 2010 or newer, as well as the recently released iMac Pro 2017.

​Unfortunately, Apple doesn't provide details on the improvements or bug fixes that landed in this second macOS High Sierra 10.13.3 beta update, but you should rest assured that it's here to improve the security, stability, reliability, and compatibility of your Mac, always. So make sure you update if you're running the first macOS 10.13.3 beta.

macOS 10.13.3 High Sierra Public beta 2 should soon be ready for download for public beta testers. Meanwhile, the upcoming iOS 11.2.5, tvOS 11.2.5, and watchOS 4.2.2 operating system are still in their first beta releases, but a second beta update should be available for download this week, probably on Wednesday, December 20, 2017.
