Which of the following is a case-sensitive volume type in macOS?

  1. Volume - Mac OS Standard

  2. Volume - Mac OS Extended

  3. Volume - Mac OS Extended (case sensitive)

  4. Volume - Mac OS Extended (Journaled)

The correct answer is: Volume - Mac OS Extended (case sensitive)

The option that indicates a case-sensitive volume type in macOS is Mac OS Extended (case sensitive). This volume format distinguishes between files and folders based on case, meaning that "Document.txt" and "document.txt" would be treated as two separate files. This differentiation can be important for developers and users who require specific file naming conventions. The other volume types listed do not support case sensitivity. For instance, Mac OS Standard and Mac OS Extended are designed to treat file names as case-insensitive, meaning they would recognize "File.txt" and "file.txt" as the same file. Journaled versions of these formats, such as Mac OS Extended (Journaled), also maintain case insensitivity while adding features for journaling, which helps maintain the integrity of the file system during unexpected shutdowns. Therefore, Mac OS Extended (case sensitive) is the only format provided that offers case sensitivity among the options listed.
