NoEjectDelay does not work on developer-only beta of macOS. Why?

We need to modify secret values of macOS to performs purpose of NoEjectDelay.

It requires SDK for new macOS. However, SDK will not be published until new macOS is shipped.
Therefore, NoEjectDelay is intentionally disabled on beta version of macOS.

Please wait until new macOS is shipped from Apple. And please wait new version of NoEjectDelay for new macOS.
