In a significant number of cases, computers running the latest versions of the mac OS operating system lag when it comes to firmware—potentially leaving a core part open to compromise.

(EFI firmware is the first part of a Mac’s programming that runs after a computer is turned on.) The researchers made a surprising discovery.

But there’s a problem; should a firmware update fail, users aren’t warned.

“There’s no notification that an EFI update failed—no retry, it’s just a silent failure,” Smith says.
