Does this stop you from using Cursor

Yes - Cursor is unusable

Hey @Burak_Gundogdu, sorry you’re stuck. Your sign-in is completing on our side, but the app on your Mac isn’t checking back in to collect it. That’s usually a VPN (or its ad/tracker blocking), a proxy, or a firewall blocking the app’s connection, or “Allow” opening a different Cursor than the one you logged in from.

Try: quit Cursor fully (Cmd+Q), turn off any VPN / ad-blocker / proxy / firewall, confirm there’s only one Cursor in /Applications, then Log In again and click Allow.

If it still fails, two things will pin it down:

  1. In Terminal (we expect 404):
curl -sS -o /dev/null -w "%{http_code}\n" "https://api2.cursor.sh/auth/poll?uuid=test&verifier=test"
  1. Command Palette (Cmd+Shift+P) → Developer: Toggle Auth Debugging, click Log In again, then View → Output and paste the auth debug channel (strip anything token-like). Also tell me your Settings → “proxy support” value.
