Environment Details

  • Product: Antigravity IDE
  • Version: 2.5.5-4923483625488384
  • Platform / Architecture: macOS (Apple Silicon / darwin-arm64)
  • Download Source URL: https://edgedl.me.gvt1.com/edgedl/release2/j0qc3/antigravity/stable/2.5.5-4923483625488384/darwin-arm/Antigravity%20IDE.dmg

Summary

The latest macOS Apple Silicon installer (Antigravity IDE.dmg v2.5.5) appears to have been released without a valid Apple Developer ID signature / stapled Apple Notarization ticket. As a result, macOS Gatekeeper blocks the installation and execution with a malware verification error.

Steps to Reproduce

  1. Download the official macOS Apple Silicon installer from antigravity.google/download (Build 2.5.5-4923483625488384).
  2. Open Antigravity IDE.dmg.
  3. Attempt to drag Antigravity IDE to /Applications or launch the application.

Observed Behavior

macOS Gatekeeper intercepts the application and displays the following blocking prompt:

“Antigravity IDE” Not Opened
Apple could not verify “Antigravity IDE” is free of malware that may harm your Mac or compromise your privacy.
[Done] [Move to Trash]

Users cannot drag the app to Applications via Finder or launch it without manually stripping quarantine attributes.

Expected Behavior

The .dmg and .app bundle should be signed with a valid Apple Developer ID and notarized via Apple’s notary service (xcrun notarytool / stapler staple) so standard macOS users can install and open the application seamlessly.

Addition information:

  • I can open the app directly in the mount when open the .dmg

  • I can not move the app to ~/Applications

Hi @Han_Nguyen,

Did you downloaded the Antigravity IDE application directly from our official website?

If you downloaded it from a third-party mirror or package manager, you might be running an outdated or unsupported version. Please download and install the absolute latest release of the Antigravity IDE directly from our official site: Google Antigravity - Download

Hi @Ambati_Rajendra , After retry, the issue is addressed with the same file. Maybe my machine have some problem from Apple. Recommend for someone like me is restart the machine and retry multiple time.
