When you have so many customers it's worth spreading the downloads over several days or even weeks.
Do you want to wait weeks for security fixes?

I wonder what happened to the "rapid security response" update mechanism that Apple implemented in Ventura and iOS/iPadOS 16. I feel like it's only been used once, maybe twice, and I would think this kind of security fix update would be a perfect fit for the rapid response mechanism.

The install on my m1 mbp Looked suspicious with several Stuck Progress Bars and black screens for minutes. Cant they make that less creepy?
That's really annoying with those many progress bars that doesn't say anything and you don't know what's happening. They mostly don't even show any percentage or time remaining and move very strange. I have this with every beta update.
