[10.15] Erase and install

[Sylvain La Gravière]

On a 10.15 redeployment, the “read-only” main APFS system volume isn’t remove.

[Christian Behrens]

Yes, with the new separation of system and user data in two volumes, it would be great if the whole disk could be erased before installing the OS.

The current 2.0 removes all apfs volumes that are in the APFS container of the specified volume. Please check and close if it works as expected
