Check filesystem in macOS High Sierra, check macOS or OSX version

Picture shows macOS High Sierra installed on HFS+ filesystem.

To determine OS X or macOS version, open Terminal.app and type:
system_profiler SPSoftwareDataType
or
sw_vers -productVersion

To determine filesystem you are using now, type the following in shell:

mount | grep ‘ / ‘
This command will show you what disk partition is mounted as the root filesystem (/) and with what options – there is a bracket and first word inside should state ‘hfs’ or ‘apfs’.
