Apple never wanted you to run macOS from a read-only DVD. They certainly never wanted you to run it on a cheap Dell Inspiron or an HP Pavilion from Circuit City. But the dream persisted: a live, bootable OS X environment that required no installation, no hard drive wipe, no baptism into the Church of Cupertino.
Once you've created the Live DVD image, it's time to burn it to a blank DVD:
However, macOS’s kernel and boot process (boot.efi, mach_kernel, and the BootX bootloader) expect a writable root filesystem. Mandating that the entire OS runs from a read-only compressed image requires extensive modifications to the boot arguments ( rd=udf , -s for single-user mode) and initramfs-like structures. Most attempts fail at the "Still waiting for root device" error—a direct result of the optical drive’s latency and the system’s inability to mount the compressed DMG in time.
