ghostty-bin: fails to launch on aarch64-darwin with code signature invalid since 1.3.0

[tolkonepiu]

Nixpkgs version

• Unstable (26.05)

Describe the bug

ghostty-bin stopped launching correctly on macOS starting with version 1.3.0. The same issue is still present in 1.3.1.

On launch, macOS immediately terminates the app with a code signing error:

EXC_CRASH (SIGKILL (Code Signature Invalid))
Termination Reason: Namespace CODESIGNING, Code 4, Launch Constraint Violation

This appears to affect the packaged .app bundle used by ghostty-bin on Apple Silicon macOS.

Steps to reproduce

1. Install or update ghostty-bin to version 1.3.0 or 1.3.1 from Nixpkgs on macOS.
2. Launch Ghostty from the application bundle or via the generated app entry.
3. Observe that the application does not start.
4. macOS immediately kills the process with a code signing / launch constraint violation.

Expected behaviour

Ghostty should launch normally on macOS, as it did before version 1.3.0.

Additional context

A previous ghostty-bin version worked correctly on the same machine before upgrading.
Reinstalling the package did not resolve the issue.
