When was SIP instituted? Because a couple of years ago on my mid-1012 MBP I downloaded an open source office suite. I can't remember now whose it was. After that my Mac went to a slow crawl. I still had AppleCare at the time and was told to download Malwarebytes. It found it immediately and tossed it. Whew! Everything sped up. It hasn't found anything since then, though. They supposedly keep it updated, but I am sure they don't have all the malware in their bag of tricks.
Of course, but I was really asking whether, SIP notwithstanding, there are still areas of OS X/macOS in which bad guys can place the sort of malware we've seen over the years...the sort of malware that LS can intercede against?
I don't recall a single such threat having arisen since SIP was instituted. [/quote]
