With .x updates, not much usually happens during the beta phase, but in the case of major releases things are different. Visible changes and adjustments can usually be observed right up to the fourth or fifth beta – partly based on early feedback, but also by fixing known problems. From now on, macOS 27, iOS 27, iPadOS 27, visionOS 27 and tvOS 27 are available as new developer versions in Apple’s developer area. This is the first update to the builds distributed two weeks ago after the keynote concluded. Most important topics in System 27: Siri AI, Apple Intelligence, lots of details
During the opening event, it was clear that Apple Intelligence and Siri AI are the focus of the new system version. Apple is also concentrating more on the platform idea, in which the respective devices retain their own characteristics but become even more similar in terms of functions and UI design. The company is also making numerous detailed improvements – in addition to optimizations that are intended to ensure more speed. We have linked some articles on this below this message. We will provide the specific innovations of the second beta in this news as soon as the first discoveries are made.
Update: First known new features in Beta 2
- There had been many reports that Siri’s indexing was not ready even after two weeks. It’s impossible to say whether it will be faster now – Apple removed the ad
- No measurable result, but the impression of numerous testers: Overall, iOS 27 runs more smoothly
- Siri AI gives answers faster
- “Write with Siri” replaces the previous writing tools
The current beta versions
Finally, as always, the well-known list of currently available beta versions. There is currently no public beta; according to Apple’s announcement, this will most likely follow in two, at the latest in four weeks – we were talking about “in July”. It will take around 2.5 months until the updates with version number 27 are generally released, as Apple is expected to continue to adhere to the usual schedule. For many years, Apple has chosen September for this, only sometimes major updates only appeared in October (macOS, iOS always arrived on time before the new iPhone generation went on sale). The build numbers of the first developer versions ended in “q”, now it is already “g” and “h”.
