Firmware could not be validated during install?
The firmware error has a couple suggested fixes. The one that worked for me when I got it on one of the betas was to disconnect all windows drives. In fact, safest to disconnect any other drive you don't need and reconnect after install.

If that doesn't help, @RehabMan reports that setting your firmware version to a newer version fixes the issue, but I am unclear on how you do that, maybe it's a config.plist thing, like, open clover configurator, and make sure the firmware version is the latest up-to-date firmware for your SMBIOS? Not clear on that solution.

It is the same thing:

Code:
<key>CsrActiveConfig</key>
<string>0x67</string>
In Clover options -> System Parameters -> System Integrity Protection you can see. 0x67 is enough. 0x3 is not.

Did somebody try updating a dual boot system?

I’m having Sierra and Windows on two separate SSDs as well as a separate NTFS-formatted HDD in my system and am afraid, that the switch to APFS could mess things up.

Went really well the update.
Just added fakesmc.kext to efi/clover/kexts/other
Disabled SIP
Updated lilu and intelgraphicsfixup.kext to 1.1.7
Working fine so far.
But 144hz is still not working

Read that High Sierra will (weekly?) check your EFI as a security precaution and compare against known good files.

Is this a surprise to anyone? Is there potential Apple might use this to throw a wrench in non-Apple hardware?

I updated a dual boot system. The High Sierra installer did not touch the Windows disk or the HDD. The only other drive is an NVME and High Sierra did not convert it to apfs, possibly because the installer couldn't see it? Or High Sierra only converts the drive you're installing to but I've heard mixed reports on that. Safest to disconnect other drives. I did not disconnect the nvme when I upgraded (or any drive) FWIW.

It's not a problem as you can see :)

Fast download, smooth update.. a shame there's no webdrivers. I guess HS will sit on my testdrive until there is (if there is)

I read it as, improving security, making sure real Macs have up-to-date firmware, nothing Big Brotherish. non-Apple hardware has been around so long now I would be surprised if Apple suddenly started going out of it's way to mess with it. After all once you go Mac you never go back. Or something. ;)

Make sure SIP is disabled (not just kext signing and filesystem), latest Clover and you should run the update app from the start every time you get this error.
