a. Extensions—Attach themselves to the system kernel to provide hardware and peripheral driver
support.

f. Logs—Text files that contain error and progress entries from nearly any app or system service.

Question 3

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.

Question 4

What purpose does the ~/Library/Containers folder serve? What items are in this folder?

Answer 4

The ~/Library/Containers folder contains resources for sandboxed apps. macOS Mojave 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 only items inside its container. Only items intended for sharing are in
a group container folder.

Question 5

How does System Integrity Protection help ensure that macOS Mojave system resources remain
secure?

Answer 5

System Integrity Protection prevents users and processes with administrator or root access from
modifying core macOS Mojave items. Protected items include the /System, /bin, /sbin, and /usr folders
along with core macOS Mojave apps.

Question 6

Which app should you use to enable, disable, or validate a font or add a font to the local font library?

Answer 6

You can use Font Book to enable, disable, or validate a font or add a font to the local font library.

Question 7

How can you identify duplicate fonts?

Answer 7

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