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.

Hello,

Thank you for sharing your concern with us.

To use Antigravity, you may need to verify your age. You can complete this process at the following link: https://myaccount.google.com/age-verification.

Additionally, we recommend referring to the full list of supported regions here to confirm availability in your area.

I have verified the age. The Pakistan region is also in supported region but still having the same issue.

Hi there!

I had this issue on windows 11 OS.

I changed the default browser to Opera.
Deleted antigravity folder from C:\Users\{User}\AppData\Roaming.
Reinstalled the antigravity.
And then authenticated using opera browser(changed in first step).

Now it is working fine.

(solution from another post, adapted to MacOS)

"The Solution (Safe Direct Injection): We need to inject a simple patch (BigInt.prototype.toJSON = function() { return this.toString(); }:wink: to the very first line of the core file without breaking its encoding.

Close Antigravity completely.

Open CMD (Command Prompt).

Copy the code below, paste it into CMD, and hit Enter."

FILE_PATH=“/Applications/Antigravity.app/Contents/Resources/app/out/main.js” PATCH=“BigInt.prototype.toJSON = function() { return this.toString(); };”

(echo “$PATCH”; cat “$FILE_PATH”) > main.js.tmp && mv main.js.tmp “$FILE_PATH”
