Question 4

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

Answer 4

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

SIP 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.
