In what ways can apps in macOS use notifications? (Select three)

Apps in macOS can utilize notifications through several methods that enhance user engagement and communication. Badges serve as a visual indicator on application icons, informing users of new notifications or updates without needing to open the app. This type of notification is particularly useful for keeping the user informed about messages, tasks, or alerts received while they are using other applications or working within the operating system.

Alerts are another crucial method of notification in macOS. They pop up in front of the user, providing immediate visibility and requiring the user's attention. Alerts can carry important information or prompts that affect the user's experience, such as reminders, updates, or messages directly from the application.

The third method, SMS verifications, is not relevant to macOS notifications as it pertains more to mobile devices and messaging services rather than within the macOS ecosystem. Similarly, email notifications are typically handled through email clients and may not be categorized as native notifications from macOS applications.

The combination of badges and alerts allows applications on macOS to effectively communicate important information and keep users aware of updates, thus improving the overall user experience.
