Siri AI / Apple Intelligence never activate. Extensive testing rules out account/region as the cause — this looks like a broken asset delivery / enrollment pipeline.
Symptoms:
- Console (subsystem com.apple.GenerativeModels) shows repeated calls:
isUseCaseAccessNotGrantedSecure: user=501, input=["com.apple.Siri.EnhancedSiriDisablement"] isUseCaseAccessNotGrantedSecure: returning granted (false); no pendingEnrollment for any of [...] ["com.apple.Siri.EnhancedSiriDisablement"] -> false
This is consistent across hundreds of calls — the system never attempts enrollment, it just returns false immediately, every time.
-
Settings > General > iPhone Storage shows 3.38GB already allocated to "Apple Intelligence," but the feature never activates — suggesting an incomplete/corrupted asset set rather than missing data entirely.
-
Toggling Wi-Fi off prompts a ~9.5GB "intelligence tools" download. Confirming it produces no progress and no result.
-
Siri language pack downloads get stuck at 100% and never proceed to activation.
-
Search and Siri Suggestions indexing (Settings > Siri & Search) initially shows no percentage, disappears, then reappears days later with a percentage stuck for 24+ hours despite "Last updated: X minutes ago" continuing to refresh — suggesting the background worker is alive but stuck, possibly hitting the same broken asset service.
-
Region-dependent behavior (most useful clue): in a region NOT eligible for Siri AI (Ukraine), legacy Siri (old interface) responds normally to "Hey Siri." In a region eligible for Siri AI (US — tested with a brand-new Apple Account, region set to US, no data restored from backup), "Hey Siri" activates (wake word detection works) but the request hangs indefinitely with no response, and legacy Siri does not answer either.
This suggests the system correctly detects eligibility, but there is no fallback to the legacy Siri response pipeline when the region is eligible yet the new Foundation Models assets fail to finish downloading/activating.
Already tried (no effect on any of these):
- Reset Network Settings
- Reset All Settings
- Multiple restarts, multiple Wi-Fi networks, cellular data
- Changing device Language & Region to US
- Fresh Apple Account created with US region, Payment Method: None, signed in clean (no backup restore) — identical isUseCaseAccessNotGrantedSecure: false result, legacy Siri also silent under this account
Steps to reproduce:
- Update iPhone 15 Pro to iOS 27 beta 3 or 4 via Software Update (not clean install).
- Settings > Apple Intelligence & Siri — no functional enrollment progress.
- Toggle Wi-Fi off — download prompt appears, confirming does nothing.
- Say "Hey Siri" — activates, no response.
Has anyone else on iPhone 15 Pro hit this specific isUseCaseAccessNotGrantedSecure / no pendingEnrollment pattern? Any word on whether this is a known/tracked issue for beta 5?
