The software addresses a bug <a href=\"https:\/\/appleinsider.com\/articles\/26\/09\/21\/neural-engine-timeouts-face-id-panics-hit-apples-newest-devices\">that caused<\/a> the Apple Watch Series 12 and <a href=\"https:\/\/appleinsider.com\/inside\/apple-watch-ultra\" title=\"Apple Watch Ultra\" data-kpt=\"1\">Apple Watch Ultra 4<\/a> to restart unexpectedly.\n<\/p>\n<p>Those who encountered the now-resolved issue said their <a href=\"https:\/\/appleinsider.com\/inside\/apple-watch\" title=\"Apple Watch\" data-kpt=\"1\">Apple Watch<\/a> rebooted while editing watch faces, making calls, using <a href=\"https:\/\/appleinsider.com\/inside\/siri\" title=\"Siri\" data-kpt=\"1\">Siri<\/a> AI, opening <a href=\"https:\/\/appleinsider.com\/inside\/apple-maps\" title=\"Apple Maps\" data-kpt=\"1\">Apple Maps<\/a> or the <a href=\"https:\/\/appleinsider.com\/inside\/app-store\" title=\"App Store\" data-kpt=\"1\">App Store<\/a>, and recording workouts. Some Apple Watch owners have even said their devices restarted when idle.\n<\/p>\n<p>As for what caused the reboot bug on watchOS 27.0, an Apple forums <a href=\"https:\/\/discussions.apple.com\/thread\/256360354\">post<\/a> outlined a Neural Engine timeout on an affected Apple Watch model. In short, a Neural Engine command waited 2,020 milliseconds, exceeding a 2,000-millisecond limit, after which the device rebooted.\n<\/p>\n<p>While the watchOS 27.0.1 update addressed these spontaneous reboots, Apple did not disclose what caused them.\n<\/p>\n<p>The company&#8217;s <a href=\"https:\/\/support.apple.com\/en-us\/100100\">website<\/a> says there are no CVE (Common Vulnerabilities and Exposures) entries associated with watchOS 27.0.1. This suggests the software likely doesn&#8217;t include major security fixes and that this release did not patch any significant vulnerabilities.\n<\/p>\n<p>The same page also outlines that watchOS 27.0.1 is available only for Apple Watch Ultra 4 and Apple Watch Series 12. In short, it&#8217;s a bug-fix update for the 2026 Apple Watch lineup.\n<\/p>\n<h2 data-anchor=\"how-to-update-to-watchos-2701\" id=\"how-to-update-to-watchos-2701\">How to update to watchOS 27.0.1<\/h2>\n<ol>\n<li>Ensure the Apple Watch is charged to at least 50% and connected to Wi-Fi<\/li>\n<li>On your Apple Watch, open the Settings app<\/li>\n<li>Tap General<\/li>\n<li>Tap Software Update<\/li>\n<li>Tap Install if a software update is available<\/li>\n<li>Follow the on-screen instructions<\/li>\n<\/ol>\n<h2 data-anchor=\"how-to-update-to-watchos-2701-via-iphone\" id=\"how-to-update-to-watchos-2701-via-iphone\">How to update to watchOS 27.0.1 via iPhone<\/h2>\n<ol>\n<li>Ensure your watch is charged to 50% and connected to Wi-Fi<\/li>\n<li>On your <a href=\"https:\/\/appleinsider.com\/inside\/iphone\" title=\"iPhone\" data-kpt=\"1\">iPhone<\/a>, open the Apple Watch app<\/li>\n<li>Tap General<\/li>\n<li>Tap Software Update<\/li>\n<li>Download the update if it is available<\/li>\n<li>Follow the on-screen instructions<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>Apple&#8217;s watchOS 27.0.1 update has arrived with a fix that prevents Apple Watch Ultra 4 and Apple Watch Series 12 models from randomly restarting.
