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

Apps in macOS utilize notifications to engage users and keep them informed about important updates or activities. Understanding the different types of notifications is essential for both users and developers.

Badges serve as a visual indicator on an app's icon, displaying numbers or symbols that denote the number of notifications or alerts within that app. This allows users to quickly recognize if there are pending items that require attention without opening the application.

Alerts are pop-up messages that appear in the macOS interface. They are designed to capture the user's attention and can convey important information or prompt users for action. Alerts can provide critical updates, warnings, or confirmations, ensuring that users do not miss significant events related to the application.

While SMS verifications and emails can be means of communication, they are not direct forms of notifications utilized within the macOS notification system as seen with badges and alerts. SMS verifications typically fall under communication methods outside the app's direct notification framework, and emails, while useful, do not integrate into the notification center specifically designed for macOS apps. Therefore, badges and alerts are direct components of the macOS notifications system.
