Apple has released watchOS 27.0.1, a minor update to the watchOS 27 operating system that was released earlier this month. The update will only be available for Apple Watch Series 12 and Apple Watch Ultra 4 wearables.
Apple’s release notes say the update fixes bugs, including an issue that could cause the Apple Watch Series 12 or Apple Watch Ultra 4 to restart unexpectedly.
watchOS 27.0.1 can be downloaded for free through the dedicated Apple Watch app on the iPhone by going to “General” -> “Software Update.” The Apple Watch needs to have at least a 50% battery charge, needs to be on a charger, and needs to be in the range of the iPhone.
