I cannot write the DVD in a 4,7Gb single layer disk, the DMG file is bigger. Any solution or how can I make the DMG bootable with a USB stick?

From where did you acquire your .dmg file ?

So... Mountain Lion is now free from Apple but it comes as a .pkg file I can't run in Big Sur. Is there any way to set up Unibeast using this .pkg file?
