If you’ve been experimenting with APFS, perhaps you’ve already tried to delete your APFS partition. You probably found out that it’s not easy. Jeff Butts went through several methods, and has landed on what seems to be the cleanest way to delete your APFS partition when you’re done with it.
Under macOS Sierra 10.12.4, you know have limited support for an APFS drive. You won’t find the option to create one in Disk Utility, but Jeff Butts is here to demonstrate how to get the APFS drive created and mounted using Terminal and the diskutil command.
