This can be annoying (what do you mean I need to wait for a separate download before I can play Minecraft?!), but it seems reliable enough, and it does ensure that you’re using the most recent version of whatever component it is that you’re downloading.


Whenever you install a program or device that needs to make use of one of these elements, Software Update pops up and prompts you to download and install it. This isn’t the product of optimization on Apple’s part, but rather the effect that the download-only decision has had on the rest of the OS: many components that were previously bundled (whether by default or optionally), including print drivers and the Java runtime environment, are now downloaded on-demand. A 3.49 GB download is a big one, but it’s slimmed down significantly from the Snow Leopard installer (my standard 10.6.3 Snow Leopard DVD is about 7.3 GB in size).
