Apple isn’t immune to Meltdown and Spectre, the major bugs in basic computing architecture that were announced yesterday to widespread amazement and horror. In an announcement, the company said that “all Mac systems and iOS devices are affected,” which sounds right, but that mitigations are either already in place or on the way.

If you’re still not clear on the whole debacle, I went into detail on it yesterday. Basically a couple of tricks processors have been using for decades turn out to have a couple extremely serious vulnerabilities and could be used to reveal all kinds of protected data to malicious actors.
