What file system is typically associated with macOS?

The file system that is typically associated with macOS is HFS+ (Hierarchical File System Plus). This file system was introduced by Apple in 1998 as an improvement over the original HFS, and it has been the primary file system used in macOS for many years. HFS+ supports features such as journaling, which helps protect the integrity of the file system against corruption, and it allows for efficient storage of files through the use of hard links and symbolic links.

While ext4 is a file system commonly used in Linux environments, NTFS is primarily associated with Windows operating systems, and exFAT is often used for external drives and flash storage due to its compatibility across different operating systems, none of these are the default or typical file systems found in macOS. Therefore, HFS+ is the correct choice when discussing the file systems commonly associated with macOS.
