Lesson 15

Question 1

What are the four default top-level folders visible in the Finder?

Answer 1

The four default top-level folders visible in the Finder are:
• Applications, containing applications all local users have
access to
• Library, containing system resources all local users have access to
• System, containing necessary system resources
• Users, containing all the local user home folders

Question 2

What are six common system resources? What purpose does each resource serve? Where are they located in the file hierarchy?

Answer 2

Six common system resources are:
• Extensions, which attach themselves to the system kernel to provide hardware and peripheral driver support
• Frameworks, which are shared code libraries that provide additional software resources for both applications and system processes
• Fonts
• Preference files, which contain application and system
configuration information
• LaunchAgents and LaunchDaemons, used by launchd to provide services that automatically start when needed at system startup, or at user login
• Logs, which are text files that contain error and progress entries from nearly any application or system service

Question 3

What are the four system resource domains? What purpose does each domain serve?

Answer 3

The four system resource domains are:
• User, containing applications and system resources specific
to each user account
• Local, containing applications and system resources available to all users on the local Mac
• Network (optional), containing applications and system resources available to any Mac that has an automated network share
• System, containing applications and system resources required to provide basic system functionality

Question 4

What purpose does the ~/Library/Containers folder serve? What items will you find in this folder?

Answer 4

The ~/Library/Containers folder contains resources for sandboxed applications. The system creates and maintains a separate container folder for each sandboxed application the user opens. A sandboxed application is more secure because it can only access items inside its container.

Question 5

What happens when a user double-clicks a font file?

Answer 5

Double-clicking a font file automatically opens a preview of the font in the Font Book application. From here, the user can click the Install Font button to copy the font into ~/Library/ Fonts.

Question 6

How can you identify duplicate fonts?

Answer 6

The Font Book application shows a small dot next to the name of any font that has duplicate resources.
