Mac Application bundle and associated signing script to demo possible bug in OS X 10.11
To run:
./sign_app.sh "Developer ID Application: My Id"
To verify:
codesign -vv target/apps/shell-script/HelloWorld.app/ codesign -vv target/apps/objective-c/HelloWorld.app/
It should say:
HelloWorld.app: valid on disk HelloWorld.app: satisfies its Designated Requirement
But in the bad case says:
HelloWorld.app: invalid signature (code or signature have been modified)
