They totally intentionally installed the software. You can't make a machine Malware proof without also making it software proof... Anyone who tells you different is confusing the issue. OS X has plenty of problems, this isn't one of them.
You're presenting a false dichotomy. You can make OS's more resistant to malware and harder to write malware for without making it completely proof from malware.
In fact, this semi-academic essay goes even further by arguing that OSes can and should be made completely resistant to malware, through things such as sandboxing (which you mention). Of course, there is no OS that fully achieves this—let alone conveniently—but that's no reason not to ask for it.
