Description

When launching Rustcast on macOS, the application is blocked by Gatekeeper. While macOS normally offers a “Open Anyway” option, this workaround is not available on MDM-managed devices (e.g. school or corporate Macs).
As a result, Rustcast cannot be used at all in managed environments, even when users explicitly trust the application.

Steps to Reproduce

• Attempt to launch the application.
• Gatekeeper blocks the app with a warning that it cannot be verified. On an MDM-controlled device, the “Open Anyway” / “Allow Anyway” option is unavailable or disabled by policy.

Impact

This issue prevents the use of Rustcast in managed macOS environments, which is a common setup in:

• Educational institutions
• Corporate IT environments
• Organizations with security compliance requirements

Environment

• macOS 26.2
• Device managed via MDM

Suggested Fix

To resolve this issue, one of the following would be highly appreciated:

• Proper macOS code signing with an Apple Developer ID
• Notarization of the application by Apple
