Apple has issued a third round of developer betas for testing, including betas of OS 12.1.3, macOS 10.14.3, watchOS 5.1.3, and tvOS 12.1.2. All four are now available for download.
iOS 12.1.3 beta three is build number 16D5037a, macOS beta build three is build number 18D38a, the third watchOS 5.1.3 beta is build 16S5535a, and the newest build for tvOS 12.1.2 is 16K5534a. (Via AppleInsider)
The new builds are available to developers over the air on the devices with the proper configuration installed. Developers can also download the new betas from the Apple Developer Center.
Public beta versions of iOS 12.1.3 and tvOS 12.1.2 are also available.
The betas number indicate they contain bug fixes and performance improvements, and likely don’t include any new features.
As usual, MacTrast and Apple both warn users to not install the beta on your daily driver iOS, Apple TV, Apple Watch or Mac computer, instead only install it on a device set aside for testing purposes.
