The cadre of the processor stores the and so-called kernel data, which regular apps and processes normally shouldn't accept access to. Or so everybody thought.

To Apple's credit, it took but a few days for the company to release the prepare, which aimed to seal the security pigsty. But equally hardware tests showed, the patches to macOS Loftier Sierra seriously affected the OS performance, according to some estimates, slowing Macs downward by 10-30 percent.
