Apple has released watchOS 9.0.1 for Apple Watch Ultra to address bugs and performance issues that may affect day-one adopters.
The Apple Watch Ultra arrives in customers' hands on Friday, September 23, and it will need an immediate update. It isn't clear what the update addresses, but if users want to avoid service issues or other setup problems, it should be the first thing they do.
If the update isn't automatically installed after setup, perform the update manually.
To update an Apple Watch:
- Open the Watch app on iPhone
- Tap "General"
- Tap "Software Update"
- Select the update option and place the Apple Watch on a charger
The update will begin when the Apple Watch is on the charger and has more than 50% charge.
