## Why are macOS updates so large?
macOS by default uses a sealed system volume that is unwritable. When the seal is broken, macOS thinks the volume is broken and downloads a full copy of macOS for every update to "repair" it to a known state. In order for root patching to work, this seal has to be broken since root patching by design requires on-disk file manipulation. This is also why root patches have to be reinstalled after each update.
