For those who are not in the US, I managed to enable it on macOS by setting three things :<p>- In General > Language and region : Both Language to English US AND region to US
- In Apple Intelligence : Set siri language to English US.<p>Then you need to reboot your mac. You'll have to apply to a waiting list, in Settings > Apple Intelligence. In my case it only took a few minutes.<p>Same procedure doesn't work for me on iPad where it says I'm region locked. Even with a VPN. As far as I remember, Apple introduced a pretty efficient daemon in iOS/iPadOS to detect region (for Europe's App Store easing of restrictions) and it's likely what's blocking there.<p>I'll refrain from too many early comments, but it seems fairly limited.<p>Asking a question about macOS (How to change DNS) will trigger a AI response that quotes the macOS user guide, while asking the same question about iOS will default to a basic Google Search. Haven't seen any fallback to ChatGPT, that may not be part of that beta.<p>Mail summarizing looks OK, but fails on some very long emails. When it works, the summary is fairly short (about 3 sentences max) which is probably pretty adequate.
