Today Apple has seen fit to release its next in line beta updates for iOS 12.4, macOS 10.14.6 and watchOS 5.3 to developers. If you’re a registered developer and want to install the latest beta for yourself, be sure to follow the steps below. Let’s dive in to see what new changes have Apple implemented in the mix and what developers should look forward to.

Starting off with iOS 12.4 beta 5, you can install it through the Apple Developer Center or over-the-air. However, do take note that a proper configuration profile is required from the Developer Center. Since there were no new major features discovered in the first four iOS 12.4 betas, we suspect the fifth beta will stick fast to the streak. However, there are a number of bug fixes and performance enhancements.
