Since then, Apple has been pretty good about including EFI (extensible firmware interface) updates with its macOS security and software updates, though new evidence suggests it is not nearly enough. This time around, researchers at Duo Security took a detailed look at the firmware used in Mac systems, and found them to be lacking. This is the part of the system that makes a series of checks and instructs core components what to do, before loading up the operating system—in this instance, macOS.... Read more...
