Apple last week released watchOS 27.0.1, a minor update to the watchOS 27 operating system that was released earlier this month. The update had been only available for the Apple Watch Series 12 and Apple Watch Ultra 4, Apple has now released the update for all eligible watches, which includes Series 9 and later.
Apple’s release notes merely say the “provides bug fixes for your Apple Watch” and does not list any security fixes. Last week’s watchOS 27.0.1 release was to address a bug that was causing Apple Watch Series 12 and Apple Watch Ultra 4 devices 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.
