Yet another move by apple to take away your control over your own machine. Some parts of the filesystem become off limits, even as root. But installers have access! That&#x27;s kinda nuts.<p>Obviously: most users wont care or notice. But when you combine this with other changes apple has made; it&#x27;s clear where they&#x27;re taking OS X: just as unfriendly to tinkering and exploration as their hardware.
