Apparently when you're downloading a 4GB XCode update with the MacOS updater, and the network gets disconnected, it fails out the whole download and has to start over from scratch.

The network gets disconnected if the machine goes to sleep. The updater does not prevent the machine from going to sleep. So you'd better not start an update and then walk away.

Every time I have to interact with Apple products, it's just a pile of shit like this. I do not understand why these things are popular.
