Overview
- Apple announced the 27‑series operating systems at its WWDC keynote and has released developer betas, with a public preview planned for July and a full release expected in the autumn.
- The company says the updates deliver wide performance gains — Apple cited up to about 80% faster transfers or loads in some cases, app start times up to 30% faster on some iPhones, and photos syncing to iCloud up to 70% faster.
- macOS 27 (Golden Gate) will run only on Apple Silicon Macs (M1 and later), iOS 27 will support all iPhones that ran iOS 26 including iPhone 11, and Apple is dropping many older iPad, Apple Watch and a few Apple TV models from 27‑series support.
- Apple Intelligence and the new Siri AI face regional and hardware limits: Apple says Siri AI will not be available in the EU at launch and that advanced on‑device features such as expressive voices and improved dictation will be reserved for the company’s most powerful, newest devices.
- Reporters and supply‑chain sources say Apple is staging some iOS 27 features and may show a rumoured foldable iPhone in September with possible shipping delays into early 2027, though those product reports remain unconfirmed by Apple.
