> I wish they'd do the Microsoft thing of letting you update based on others local downloads Apple does let you do this! It just takes a little more work to enable. You need a macOS device on your local network. Then in Preferences -> Sharing, enable “Content Caching”. This will transparently cache OS and app updates for all Apple devices on your local network. If any device requests an update your caching server doesn’t have, the caching server downloads it first and then serves it to the client. This can minorly speed up updates even when they're not already cached. It also caches shared iCloud file contents as well. (But with E2EE, so the server can’t see the content). I keep a caching server running and really see the speed up. It's great if you’re setting up a new phone and installing lots of apps, making it particularly useful for corporate IT.
