  1. Which macOS security technology prevents applications from accessing resources outside their designated container without explicit user permission?

    Answer: App Sandbox

    App Sandbox isolates Mac App Store apps in a container, restricting their access to system resources, other apps' data, and the network unless the user explicitly grants permission through entitlements.

  2. A user reports that an app purchased from the Mac App Store shows 'App Not Available' and cannot be re-downloaded. What is the most likely cause?

    Answer: The app was removed from the App Store by the developer

    When an app is removed from the Mac App Store by its developer or Apple, existing owners can no longer re-download it, even if they purchased it, as App Store distribution is tied to current availability.

  3. What type of file do macOS applications use to declare their capabilities, bundle identifier, and minimum system requirements?

    Answer: Info.plist

    Info.plist (Information Property List) is a structured XML file inside every application bundle that declares the app's bundle identifier, version, required capabilities, supported file types, and minimum macOS version.

  4. In macOS, what is a 'Universal Binary' application?

    Answer: An app compiled for both Apple silicon (ARM) and Intel (x86-64) architectures in a single executable

    A Universal Binary (Universal 2 in modern context) contains compiled code for both Apple silicon (ARM64) and Intel (x86-64) architectures within a single application bundle, allowing it to run natively on both Mac types.

  5. What happens when you hold Option while clicking 'Force Quit' for an application in macOS?

    Answer: The Relaunch button appears, allowing the app to be immediately restarted after force-quitting

    Holding Option while selecting Force Quit in the Force Quit Applications window changes the button to 'Relaunch,' which force-quits the app and immediately relaunches it — useful for frozen apps you still need to use.

  6. Which macOS feature allows iPhone and iPad apps to run on Apple silicon Macs without modification?

    Answer: iOS App Compatibility (iPhone and iPad Apps on Mac)

    Apple silicon Macs can run unmodified iPhone and iPad apps natively through iOS App Compatibility, which Apple introduced with M1 Macs. These apps appear in the Mac App Store and run in a window on macOS.
