To me this implies that the installation process on Mac OS should be improved. The fact that they have to resort to these types of things to make it “just work” for people suggests that the official way of doing things is less than ideal.
They are aiming to make the process completely idiot proof, and good for them. If you’ve ever watched a nontechnical user try to install an application you’ll understand why they had to do all this.
I recently watched One of my friends who has only ever used an iPad and not a laptop try to install an application downloaded from the internet. Things we take for granted like “find your downloads folder” were not obvious. I had to explain what the Finder is, and it seemed laughably not obvious to someone who has never used it before.
