Mac の Apple Store 用にバリデーションの受領を有効にする。
When enabled, your game will only run when it has a valid receipt from the Mac App Store. Use useMacAppStoreValidation when submitting games to Apple for publishing on the App Store. This ensures users can only run the game on the computer it was purchased on.
Note: useMacAppStoreValidation doesn't implement any strong copy protection. Any potential crack against one Unity game might work against any other Unity content. For this reason, it's recommended to implement your own receipt validation code using plug-ins. As Apple requires plug-in validation to happen before showing the screen setup dialog, you must still enable this check, or Apple might reject your submission.
