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.
Has anyone seen similar CoreLocation / GeoServices behavior where Wi-Fi scans succeed but knownCount always remains 0 and no location fix is generated?
