First iOS 27.3 and macOS Golden Gate 27.3 Public Betas Now Available

Apple today seeded the first betas of iOS 27.3, iPadOS 27.3, macOS Golden Gate 27.3, tvOS 27.3, and watchOS 27.3. The new software comes two days after Apple released the betas for developers.

iOS 27
iOS 27.3 is a major update that adds a Vertical Tabs layout option and Adaptive Dark Mode for Safari. Siri AI can do more in and across Apple's apps, and developers are now able to create actions for ‌Siri‌ to carry out.

The redesigned Health app is now available with custom Insights and Longevity information, and the iPhone Duo supports Reachability. There's a new Selfie Sing feature in Apple Music, plus changes to StandBy on non-Duo iPhones. A full list of what's new in the beta can be found in our guide.

On the Apple Watch Series 12 and Ultra 4, Audio Intelligence features Live Rewind and ‌Siri‌ Recap are available for testing. Live Rewind creates a transcript of the last 15 seconds of speech, and ‌Siri‌ Recap offers a high-level summary of conversations throughout the day.

‌macOS Golden Gate‌ 27.3 has the same Safari features, and it brings Live Activities to Macs without a Dynamic Island.

To get the new betas, you can sign up on Apple's beta testing website. After you're signed up, the betas can be installed through the Software Update section in the Settings app on each device.

We're expecting all of Apple's updates to launch in December.

A year ago 26.2 beta was just being released around this time. 26.3 didn’t arrive until sometime in the new year. OS 27 sends to be maturing quickly.
To be fair, this would be 27.2 if it weren't for the separation of 26.1 or whatever it was for just the duo. I think they just jumped straight to 27.2 for the other phones.

Was only because 27.1 was duo exclusive.
See 27.3 as a 27.2 in regular years.

Edit: two people already beat me xD

These updates are getting pretty hefty in size - MacBook Air 15"2026 - OS Update size: 19.34GB, and the same update on my iPhone Duo is 27GB. How can an iPhone OS be larger than a desktop OS - baffling. NOTE: I personally don't use any AI / Siri features.

I usually wait a few releases before moving to a major version (e.g., IOS 26 to 27), so looking forward to 27.3.
