We focus on this in additional element right here: How secure is a Mac? and in Do Macs need antivirus software?

Nevertheless, from time to time safety vulnerabilities are detected that would be utilized by hackers to exploit Macs. These vulnerabilities are generally referred to as again doorways or as a zero day vulnerability. When these are recognized by safety researchers (or pleasant hackers) they often alert Apple to them within the hope that the corporate will shortly shut the vulnerability, shortly – or inside zero days – earlier than it is exploited. 

Such vulnerabilities, although uncommon, might permit an attacker root entry to your Mac.

Apple is often fast to repair, however there have been circumstances the place Apple has been criticised for being gradual to reply to the risk as soon as it’s been recognized.
