Which version of MacOS are you using? I believe Apple has made changes to the keychain in the latest version which prevents the scripts from working properly. The only Apple "device" I have regular access to is a hackintosh, so this stuff is frustratingly hard to debug. So far I've been relying on efforts from the community, but the scripts appear to be somewhat flaky and don't always work for everyone unfortunately.
