I think the OS is written to some kind of read only partition, and so they are having to write the whole thing each change? It's also why safari updates need reboots these days, isn't it?
- dcow 3y agoHow do you write it if it’s readonly? Whether or not the system partition is mounted readonly for daily use doesn't have anything to do with the update size.
- NikkiA 3y agoIt's protected by T2, the reboot disables the system security protection (SSP) temporarily in the T2, which then allows the OS partition to be written to, then it re-enables SSP and reboots. Only 'special' signed code can enable the update mode.
