macOS 10.13 beta stops installing with error "problem with firmware"

I have the same model MBA (and 10.12.6 beta) and experienced the same problem -- "error verifying firmware". I have found no solution.

I getting the similar firmware error on my Mac Pro (late 2013).

The log states: Reason: Error Doamin=com.apple.osinstall code=512

UserInfo={NSlocalizedDescription="An error occurred while verifying firmware"

I've tried installing multiple times on different media.

Same error on my Mac Pro (late 2013). 😟

Same problem here, macbook 12 inch early 2015 with macOS Sierra 10.12.6 Beta (16g12b)

High Sierra Beta 2 firmware error.

I have Mid 2015 Macbook Pro i7 16gb 480Gb SSD

Don't know if this will help BUT...

I was trying with no success like the rest of you...

I have the Mid 2015 Macbook Pro 480GB SSD 16Gb Ram i7

So I went last week and bought a New Macbook Air to try to do the beta install of High Sierra.

It worked with no problems at all.

So I thought I'd try and experiment.

I used Carbon Copy Cloner(demo) and cloned the New Macbook Air with High Sierra via USB to and external laptop hard drive.

There were warnings about High Sierra not being supported but it went fine.

I took that drive and put it in my Macbook Pro and booted into that drive to start High Sierra.

No problem with that.

The I used Carbon Copy Cloner again and cloned the High Sierra from the Macbook Air to my Macbook Pro.

A few warnings again from carbon copy cloner but no problems.

Shut it all down and removed the external usb drive.

Rebooted to just the Macbook Pro and Voila!!

I did notice that it took longer than normal after powering on for the Apple to appear. In fact at first I thought it wasn't coming up but it did!

Once it was up, there was a little struggle with Icloud not recgonizing my password.

I did a sign out and saved the icloud data to my drive then signed back in. Once again either I misstyped or it didn't recoginize my password but the second time i typed it , Voila! it worked.

So I'm taking back the new Macbook Air ... lol

Downloading xcode now... on the Macbook Pro...

We'll see how that goes!

Same issue with Late 2010 MBP and OSX 10.12 beta installing on SSD.

No difference if I install with or without upgrading to APFS.

Same problem with Publik Beta

If I may ask, has anyone done any modifications to their hardware?

My MBA 2014 upgraded just fine. My MacBook Pro late 2012 did not and I am curious if its because I made my own fusion setup by moving the original drive to the second bay and adding a non-standard SSD in the original bay.

That is the only thing that I can think of that would be "firmware" related besides the mac. Well that and checking for the original superdrive firmware.

Thoughts?

I finally got a working solution but it took a lot of time. I will separate my steps with action items that were inconclusive and then the ones that were a bit more conclusive. Everything was done in this order:

Inconclusive:

1) Reboot and reset SMC

2) Reboot and reset PRAM

3) Ran a disk first aid after the installer crashed. It is a newer version you can find form the menu.

4) Downloaded and Reinstalled the "Public Beta Access Utility" dmg from the site.

5) Logged out of the App Store and logged back in.

6) Ran installer and it failed again.

Conclusive:

1) While I was in the Public Beta dmg I verified what it was installing. (you can view this by selecting 'Show Files' after launching the installer)

2) It is installing a file called 'Beta License.lpdf' in ./Library/Documentation/

3) I removed that file and a folder called "Eagle" ./Library/Documentation/Resources

4) I deleted the macOS high Sierra installer form ./Applications

5) I rebooted and ran the 'Public Beta Access Utility' pkg again.

5) I ran the installer utility with APFS checked.

6) The install started then rebooted a couple of times.

7) During one of the reboots the firmware update screen came up! My Firmware was being updated.

8) The installer went further and then gave an unable to install.

9) I chose 'restart' and the MBP immediately went into kernel panic screen.

10) I rebooted once more with command-r and saw it was the High Sierra recovery.

11) I ran Disk Utility first aid once more from recovery. No errors but better safe than sorry.

12) I did not reboot and instead chose to reinstall macOS High Sierra from recovery.

13) I did NOT select the 'APFS' option this time.

14) The install process proceeded and it took a LONG time.

15) Computer rebooted and voila. I am in High Sierra on a non APFS drive. (I have a third party SSD in first bay and original HDD in second bay)

Crazy steps. I have not converted my Fusion drive to APFS yet. I hope this helps.

I was doing it with OWC Aura SSD and the Apple SSD, same problem, firmware error

Third party SSD indeed

I thought that as well but that firmware error has been across a bunch of differnet mac's....

I run a DIY Fusion Drive in my mid 2012 15" non-retina MBP (been running for 4 years without an issue). I kept the original HDD bay for the HDD and installed the SSD in an OWC data doubler cage in the optical drive bay space. Both drives are NON Apple (INTEL 520 SSD / WD Black HDD). I had no issues with the inline APFS conversion of the Fusion Drive during the public beta install. I have NO superdrive installed on my MBP and no warnings popped up during either the High Sierra install or the APFS conversion.

Oh. This is even after doing the steps I laid out and removing that file?

Interesting.

Curious, too. Mac Pro 2013, 4TB OWC Aura, 10.13 beta 2.

Haven't done the SMC / PRAM reset, yet. Other config ...

same thing - OWC SSD drive 3rd party installed....most definitely is the cause.....anyone have this error WITHOUT a 3rd party SSD? Apple doing this on purpose when 3rd party SSD detected.....need workaround!

I followed the steps mentioned above but no luck. Is there anything else that works. I have resarted couple of times, deleted license and Eagle file/folder and downloaded installers again and again. Not to mention I have done SMC/PRAM reset as well. I have 2013 MBA with 480GB OWC Aura SSD.
