Mac users who upgrade to macOS High Sierra will benefit from a significant new security feature that works in the background.

macos high sierra
macOS High Sierra automatically checks a Mac's EFI firmware against Apple's database of "known good" data to ensure it hasn't been tampered with, according to a series of tweets from an Apple engineer.

The tweets have since been deleted, but a summary remains available on the Mac blog The Eclectic Light Company.

The new utility eficheck, located in /usr/libexec/firmwarecheckers/eficheck, runs automatically once a week. It checks that Mac's firmware against Apple's database of what is known to be good. If it passes, you will see nothing of this, but if there are discrepancies, you will be invited to send a report to Apple.

If the check fails, a prompt will appear with options to "Send to Apple" or "Don't Send." The selection is remembered in subsequent weeks.

eficheck
The "eficheck" tool sends the binary data from the EFI firmware, and preserves user privacy by excluding data which is stored in NVRAM, according to The Eclectic Light Company. Apple will then be able to analyze the data to determine whether it has been altered by malware or anything else.

The database's library will be automatically and silently updated so long as security updates are turned on.

EFI, which stands for Extensible Firmware Interface, bridges a Mac's hardware, firmware, and operating system together to enable it to go from power-on to booting macOS.

macOS High Sierra will be publicly released on the Mac App Store later today.

Probably nothing at all.
Will just make actual Macs more secure.

This is great news as it should help to guard against any sort of tampering which might result through a bad actor having temporary physical access to a machine such as at a border security point.

I honestly don't believe that Hackintoshes are being targeted here but if increasing legitimate Mac security results in Hackintoshes having a few bumps in the road then so be it IMO.

Spoken like a government. This is probably not to fight malware but to fight hackintoshs.

This sounds like a way to get rid of Hackintoshes.

This doesn’t affect hackintoshes. HS is working on them just fine. (The Apple employee who posted the original tweets even said don’t send in your data if you’re on a hack, because it’s useless to them.)
