Using older file system (HFS+ instead of APFS) and compression (lzfse instead of lzma) allows the disk image to be opened on older versions of macOS, avoiding the cryptic error message that users are greeted with otherwise. This is a temporary fix for the still-alive installed base of Intel-based Macs.
