WatchOS 8.7.1 Fixes Bug Affecting Apple Watch Series 3 Users

Apple on Wednesday released iOS 15.6.1 and macOS Monterey 12.5.1 to all users. There are no new features updated or major changes. Instead, they come with important security improvements. The company also released watchOS 8.7.1, but this update fixes a specific bug affecting Apple Watch Series 3 models.

watchOS 8.7.1 is specifically for Apple Watch Series 3 users

According to the leaking rumors, watchOS 8.7.1 can help fix the bug that reboots unexpectedly on Apple Series 3 for some users. For this reason, the update is only working for Series 3 models, So the new updated can’t be used on Apple watch 4 and later models.

The Apple Security Updates webpage, where the company provides details on the security enhancements in each software update, makes it clear that watchOS 8.7.1 has not changed anything other than fixing a bug affecting Apple Watch Series 3 users. Both iOS 15.6.1 and macOS Monterey 12.5.1 come with security fixes.

According to Apple, one of the fixed vulnerabilities allows third-party applications to execute arbitrary code with kernel privileges. Another vulnerability found in Safari’s web engine WebKit has also been fixed with an update. The vulnerabilities affected iPhone, iPad, and Mac users.

At the same time, watchOS 9 is being developed, the major update for Apple Watch software. This new system is expected to have a new watch faces, enhancements to the Workout app, medication reminders, and more. However, watchOS 9 requires Apple Watch Series 4 and later. The Apple watch 3 won’t enjoy the update.

Just like iOS 16, watchOS 9 is expected to be officially released next month.

How to download and install watchOS 8.7.1

  1. Update your iPhone to iOS 15 or later.
  2. Connect your iPhone to Wi-Fi and launch the Watch app.
  3. Make sure your Apple Watch is charged to at least 50% and connect it to the magnetic charger.
  4. Tap on the My Watch tab.
  5. Tap on General.
  6. Tap on Software Update.
6. Tap on Download and Install.
7. Enter your iPhone Passcode when prompted.
8. Tap Agree to the Terms and Conditions

10. Tap Proceed on your Apple Watch to begin the download.
11. Enter your Passcode on your Apple Watch.
The watchOS update will download and transfer to your Apple Watch, which will restart to apply the update. You can track your progress on the Apple Watch screen, and when you’re done, you’re all set.

How to speed up Apple Watch software updates

If you’ve ever been frustrated by the time it takes to download and install updates for your Apple Watch, you should know that you can speed up the process by turning off Bluetooth when appropriate. But I would warn you not to do that.

While the steps below may work, if you time things completely wrong, you could have serious consequences for your installation and your Apple Watch. If you are confident in your ability to time correctly, you can try this at your own risk.

After tapping Download and Install in step 7 above, follow these instructions.

  1. Enter your Apple Watch or iPhone passcode if/when prompted.
  2. Open Settings on your iPhone AFTER you are given an estimate for the time remaining in your watchOS download on the Software Update page.
  3. Tap Bluetooth.
  4. Tap the Bluetooth switch so that it’s in the white ‘off’ position.
  5. Open the Watch app on your iPhone.
  6. Tap Cancel on the prompt on the Software Update page. If you’ve done everything correctly (which is again, not guaranteed), your iPhone will fall back to using your home Wi-Fi network to deliver the update rather than Bluetooth.
  7. Open Settings on your iPhone AFTER the Install button becomes available at the bottom of the Software Update page.
  8. Tap Bluetooth.
  9. Tap the Bluetooth switch so that it’s in the green ‘on’ position.
  10. Open the Watch app.
  11. Tap Install.

Once again, I would highly caution you against doing this, as it could cause major problems with the update.
