Apple Releases watchOS 27.0.1 for Additional Models
After releasing watchOS 27.0.1 for the Apple Watch Series 12 and Apple Watch Ultra 4 last week to address a bug that was causing devices to restart unexpectedly, Apple has now released the update for all eligible watches, which includes Series 9 and later. Apple's release notes say only that the update "provides bug fixes for your Apple Watch" and the company does not list any security fixes, so it's unclear what exactly is addressed with the update.
