Apple seeds fourth developer betas of iOS 10.3.2, macOS 10.12.5, watchOS 3.2.2 & tvOS 10.2.1

The iOS 10.3.2 beta can be download via Apple's developer portal, or else as an over-the-air update for people with the correct profile. The macOS code can be downloaded via Apple's website or else as a Mac App Store update.

The update process is slightly more complex with watchOS and tvOS. In the first case developers must use the iOS Watch app, and have their Watch on a charger with at least 50 percent power. In the second, an Apple TV must be connected to a computer with iTunes using a USB-C cable.

Release notes have so far pointed to minor fixes and security updates. iOS 10.3.2, for instance, should solve problems with car-related SiriKit commands.

Apple's previous round of betas was issued a week ago. Based on past trends, Apple is unlikely to release many (if any) more betas before the finished software.

Updated public betas of iOS 10.3.2 and macOS 10.12.5 will likely be available soon, if not later today. watchOS and tvOS betas aren't distributed in public form.
