watchOS 8.6, tvOS 15.5 Arrive With Minor Improvements
Along with iOS/iPadOS 15.5, Apple has also released watchOS 8.6 and tvOS 15.5
watchOS 8.6 can be downloaded now through the companion Watch app on your iPhone by heading to General > Software Update in the My Watch portion of the app. You can also go to Settings > General > Software Update on an Apple Watch
Your watch needs to have more than 50 percent power and connected to a charger. Like most Apple Watch updates, it could take anywhere from 30 minutes to an hour to complete, so be patient.
It’s compatible with the Apple Watch Series 3 and later.
According to the release notes, the update adds ECG functionality and irregular heart rhythm detection for watch users in Mexico.
Apple didn’t specify any new features in tvOS 15.5
The software should automatically be downloaded to a Apple TV HD or Apple TV 4K.
If you haven’t already enabled automatic updates, you can download the software by heading to Settings > System > Software Updates > Update Software. Right the button to update software is the toggle switch to turn on automatic updates.
