Ask HN: Why does Apple upgrade their computers to OS's they know won't work?

This must be the third time now that a friend has messaged me saying "the computer says 20 minutes remaining and it's said that for hours straight".

Look it up, and sure enough that laptop won't run the OS version Apple is trying to automatically update their computer to.

Surely Apple must be able to tell that hardware that they created cannot run an OS that they created?

How is there not a class action lawsuit over this practice yet?
