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.
The system 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.

Question 5

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

From here, the user can click the Install Font button to copy the font into ~/Library/Fonts.
