Apple issues first macOS High Sierra 10.13.5 beta to developers

Following the release of macOS High Sierra 10.13.4 on Friday, Apple has restarted the operating system testing cycle once again, issuing its first beta of macOS 10.13.5 to developers enrolled in Apple's testing program on Tuesday.

The first High Sierra 10.13.5 beta bears the build number 17F35e. The test version has yet to make its way to Apple's developer webpage, but is available through the Mac App Store for those who provisioned their Mac to run beta software.

AppleInsider is currently testing out the new beta to find out what new features have been included in this first release.

Developers are able to download macOS High Sierra 10.13.5 beta 1 via the Mac App Store and, when it goes live, Apple's developer portal.

AppleInsider, and Apple itself, strongly advise against installing beta releases on mission-critical hardware, due to the potential loss of data that can occur.

Apple released macOS 10.13.4 to the public on March 29, introducing enhanced eGPU support to the operating system. The addition makes it easier for users to connect a separate Thunderbolt 3 enclosure equipped with a dedicated video card to a Mac, which can increase the available processing power for graphics-heavy tasks, such as VR, gaming, and CAD.

Business Chat was also included, allowing users to communicate directly with companies via Messages, and even make purchases. The update also introduced more clarity on privacy and personal information, the ability to sort Safari bookmarks, and a number of other stability, performance, and security changes.

The first macOS beta also arrives one day after similar initial betas for iOS 11.4, tvOS 11.4, and watchOS 4.3.1 were released to developers.
