The security problem is deep inside the "stack". It comes from the way this world ticks: the world of people that constantly follow the latest tool-of-the-day. In many of the projects, you no longer have mostly Linux developers that co-function as system administrators, but you see a lot of Apple iFanboys now. They live in a world where technology is outdated after half a year, so you will not need to support product longer than that. They love reinstalling their development environment frequently - because each time, they get to change something. They also live in a world where you would simply get a new model if your machine breaks down at some point. (Note that this will not work well for your big data project, restarting it from scratch every half year...)
And while Mac users have recently been surprisingly unaffected by various attacks (and unconcerned about e.g. GoToFail, or the fail to fix the rootpipe exploit) the operating system is not considered to be very secure. Combining this with users who do not care is an explosive mixture...
