Notarization fails for MATLAB-compiled app for Mac due to embedded bundle.zip structure

[keitaroyamada]

Description

When submitting a MATLAB-compiled .app for notarization on macOS, the process fails with errors such as:

• “The executable does not have the hardened runtime enabled”

• “The signature of the binary is invalid”

• “unsealed contents present in the bundle root”

The failure seems related to the way MATLAB Compiler packages the runtime:

• The outer application (MyApp.app) includes Contents/Resources/bundle.zip.

• Inside this zip is another .app (MyDesktopApplication.app) with its own executables.

• Apple’s notarization service expands bundle.zip and checks binaries inside it.

• Since these are not pre-signed or hardened, notarization rejects the archive.
