   @thomasfuchs haha it said 751MB for my M1 (but I guess it’s a two-stager as was mentioned in that post that was recently kicking around), but I had the same reaction

   Even checked the security announces, nothing there. Keen to see a patch diff

     @thomasfuchs That's thanks to a MacOS security feature introduced in Sierra 10.12 called "Gatekeeper*" that requires whole disk images to be signed to protect from being modified. It means even small patches have to completely replace large chunks of the system to update.

     *Gatekeeper has technically been around for a while, but only added that extra feature starting in Sierra.

     @thomasfuchs It's more suboptimal than you'd think. Part of the update size is because Apple chooses to have a single disk image for all supported architectures, so ARM & Intel updates are included for everyone regardless of your system type, which makes updates even bigger.
