I use (mostly) Macs and I find their updating mechanisms to be useful, make sense, and are easy to control.
You are clearly given several, easy to find options, for how updating occurs.
I use the: alert me when its available, but wait for my to OK to install it approach.
If I put it the installation for some reason, it reminds me periodically, until I do it, or until I change the update alerting process.This works fine and I don't see why its so difficult for others to do it that way.
Its hard to imagine that Apple has patented it.
