 ### Case sensitivity
 
-With Docker for Mac, file systems are shared from macOS into containers in the
-same way as they operate in macOS. As a result, if a file system on macOS is
-case-insensitive that behavior is shared by any bind mount from macOS into a
-container. The default macOS file system is HFS+ and, during installation, it is
-installed as case-insensitive by default. To get case-sensitive behavior from
-your bind mounts, you must either create and format a ramdisk or external volume
-as HFS+ with case-sensitivity or reformat your OS root partition with HFS+ with
-case-sensitivity. We do not recommend reformatting your root partition as some
-Mac software dubiously relies on case-insensitivity to function.

+On macOS Sierra and lower, the default file system is **HFS+**. On macOS High
