2. 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:

• /System
• /bin
• /sbin
• /usr
• Core macOS Mojave apps
