Hi,
I’m having a blocking login issue with Antigravity IDE on macOS.
Error message
“You are not signed in to any account”
Problem description
-
When I launch Antigravity, it shows the error “You are not signed in to any account”.
-
When I try to sign in with Google, the browser login flow completes successfully.
-
However, after returning to Antigravity, the IDE gets stuck in infinite loading and never finishes the sign-in process.
-
Even after clicking Logout, the previous account information still appears, as if the session is not fully cleared.
It feels like the local auth state is corrupted or not being reset correctly, and the IDE is stuck between “signed out” and “signed in” states.
What I have tried
-
Restarting the IDE and the entire system
-
Logging out and logging back in multiple times
-
Using different browsers (Chrome, Safari, Incognito mode)
-
Disabling all browser extensions
-
Turning VPN off
-
Manually deleting all local Antigravity data:
-
~/Library/Application Support/Antigravity/Cache
-
GPUCache, Code Cache, Local Storage, Session Storage, Cookies, Service Worker, etc.
-
Also deleted machineid to force a clean state
-
-
Reinstalling Antigravity
The issue still persists.
Environment
-
OS: macOS (Apple Silicon, M1)
-
Account: Personal Gmail (not Workspace, not school account)
-
Network: Korea
Expected behavior
After logout or local data cleanup, Antigravity should fully reset authentication state and allow a clean login.
Actual behavior
Antigravity shows “You are not signed in to any account”, then after Google login it gets stuck in infinite loading and never completes authentication.
If this is related to account eligibility, regional rollout, or a known authentication bug, I would appreciate any clarification or workaround.
Thank you.
