MacBook Air (M4)
Current build: macOS 27 Developer Beta (26A5368g)
I have a system-wide Location Services failure affecting Apple Maps, Safari geolocation APIs, and any application requesting the current location.
Symptoms:
- Apple Maps cannot determine current location.
- Safari and browser geolocation APIs fail.
- Websites report that location cannot be found.
- Location Services are enabled and permissions are granted.
The issue has persisted across:
- macOS 26.5 beta
- macOS 26.6 beta
- macOS 26.6 beta 2
- macOS 27 Developer Beta
Troubleshooting already performed:
- Multiple Wi-Fi networks tested.
- iPhone hotspot tested.
- VPN enabled and disabled.
- Location Services reset.
- Permissions reset and reauthorized.
- New clean local user account created (no Apple ID, no third-party software).
- Issue reproduces identically in the clean account.
Technical observations:
locationd logs repeatedly show:
knownCount = 0 AlsWifi = unknown
while Wi-Fi scanning itself appears successful:
queryMacAddresses.size = 57
The system sees dozens of nearby access points, but none appear to be recognized for Wi-Fi positioning.
Additional findings:
- Wi-Fi hardware functions normally.
- Internet connectivity is normal.
- Bluetooth and Find My device presence work.
- GeoServices resources are present on disk.
- No successful location fix is ever produced.
Feedback Assistant reports have been submitted with sysdiagnose attached.
Has anyone seen similar CoreLocation / GeoServices behavior where Wi-Fi scans succeed but knownCount always remains 0 and no location fix is generated?
