In which folder are system-wide fonts installed for macOS users?

System-wide fonts for macOS users are installed in the /Library/Fonts directory. This location allows fonts to be accessed by all users on the system, enabling consistency and availability of the fonts across different user accounts.

In contrast, the /User/Library/Fonts directory is specific to individual users and only contains fonts installed for that user account. The /System/Library/Fonts folder contains system-provided fonts that are part of macOS itself but are not meant for user modification. The /Network/Library/Fonts folder is intended for fonts that can be shared across a network but is less commonly used in typical installations.

Thus, the /Library/Fonts directory is the correct answer as it serves as the central location for managing fonts that are available to all users on the macOS system.
