Apple: the root of the problem
For a long time, Apple has boasted - with some justification - that it has an excellent record of keeping its devices safe from intruders. In any case, with PCs having the lion's share of the computer market, hackers and security researchers used to spend little time hunting down vulnerabilities in Macs.
But on Tuesday a Turkish software developer tweeted this: "Dear @AppleSupport, we noticed a *HUGE* security issue at MacOS High Sierra. Anyone can login as 'root' with empty password after clicking on login button several times."
It sounded unlikely but it was true. What it meant was that anyone who got hold of an Apple computer running the latest operating system could get root access to the machine with very little trouble.
