What are the four default top-level folders visible in the Finder?
The four default top-level folders visible in the Finder are as follows:
A. Applications – Apps that local users have access to.
B. Library – System resources that local users have access to.
C. System – System resources
D. Users – Local user home folders
What are the six common system resources? What purpose does each resource serve?
These are the six common system resources and the purposes they serve:
A. Extensions – Attach themselves to the system kernel to provide hardware and peripheral driver support.
B. Frameworks – Shared code libraries that provide additional software resources for apps and system processes.
C. Fonts.
D. Preference files – App and system configuration information.
E. LaunchAgents and LaunchDaemons – Used by launchd to provide services that automatically start when needed at system startup or at user login.
F. Logs – Text files that contain error and progress entries from nearly any app or system service.
What are the four system resources domains? What purpose does each domain serve?
These are the four system resource domains and the purpose they serve:
A. User – Contains apps and system resources that are specific to each user account.
B. Local – Contains apps and system resources that are available to users on a local Mac.
C. Network – Optional. Contains apps and system resources available to any Mac that has an automated network share.
D. System – Contains apps and system resources that provide basic system functionality.
What purpose does the ~/Library/Containers folder serve? What items are in this folder?
The ~/Library/Containers folder contains resources for sandboxed apps. macOS High Sierra creates and maintains a separate container folder for each sandboxed app that a user can open. A sandboxed app is more secure because it can access on items inside its container. Only items intended for sharing are in a group container folder.
What happens when a user double-clicks a font file?
When you double-click a font file, it automatically opens a preview of the font in the Font Book app. From here, you can click the Install Font button to copy the font into ~/Library/Fonts.
How can you identify duplicate fonts?
The Font Book app shows a small dot next to the name of any font that has duplicate resources.
How does System Integrity Protection (SIP) help ensure that macOS High Sierra system resources remain secure?
System Integrity Protection prevents users and processes with administrator or root access from modifying core macOS High Sierra items. Protected items include the /System, /bin, /sbin, and /usr folders along with core macOS High Sierra apps.
