	hdiutil create -o /tmp/macOS -size 15000m -volname macOS -layout SPUD -fs HFS+J<br />
	# mount the temporary disk image<br />
	hdiutil attach /tmp/macOS.dmg -noverify -mountpoint /Volumes/macOSISO<br />
	# use createinstallationmedia utility to copy files<br />
	sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/macOSISO --nointeraction<br />
	# unmount the temporary disk image, alter the OS name as needed<br />
	hdiutil detach -force /Volumes/Install\ macOS\ Monterey<br />
	# convert the disk image to .iso<br />
	hdiutil convert /tmp/macOS.dmg -format UDTO -o ~/Desktop/macOS.cdr<br />
	# change the extension from .cdr to .iso<br />
