*Can an Apple OS X system suffer from a Rootkit infection too*?

A rootkit is just an exploit of software bug(s). If a software doesn't have
any bug that causes unhandled error, it can't be exploited.

In the real world, rootkits are less harmful than scamwares. Because believe
it or not, softwares have more defensive measures than most users.
