The iOS certificate flaw was nothing, right?
iOS is popular and is the target of successful hacks. Apple has issues patches numerous times, just like Microsoft has been doing for its popular operating system....Windows.
Apple has no greater security than any other device. Hacking is human versus human more than anything.
But, you want to live in denial.
It was a vulnerability. No exploits were in the wild. All it did was to cause the device to reboot. It put no data at risk and allowed no escalation of privileges. At worst, it created a denial of service for a short period. . . and the avoidance was easy. Sorry, a vulnerability without an exploit that was rapidly fixed does not equate to a lack of safety. Every OS has vulnerabilities. . . the question is are these vulnerabilities exploitable to the point a hacker can make use of them? If that answer is no, then it's a moot point.
