MP 1,1-5,1 [SOLVED] Install Mojave: An error occurred while verifying firmware

[drw026]

Hi all,

I'm having trouble clean installing Mojave on a NVME (Samsung 970 EVO 1TB). During install I get the message:
An error occurred while verifying firmware.

TLDR solution can be found here.

My main drive (Samsung 850 EVO 500GB) is holding High Sierra with OpenCore 0.6.1. In the past I've already run the Mojave installer only to update my firmware to 144.0.0.0.0 so I can install Mojave on to the NVME in the future.

I first tried to clean install Mojave by creating a bootable install USB drive. During install I used the disk utility to format the drive as APFS, but proceeding the next install step the drive was grayed out saying Your mac needs a firmware update in order to install to this volume. Please select a Mac OS Extended (journaled) volume instead. I ran disk utility again to format it to MacOS extended journaled. After that I was able to proceed the install step, which copies all files to the NVME drive. Once it reboots and proceeds the install, the message An error occurred while verifying firmware shows and restart was the only option.

My second try was installing it using the Mojave installer executing this from High Sierra and target it to the NVME. No success and also could not select APFS format.

My last try was using the stock SATA HDD as the target drive but also got the same error.

My MacPro 5,1 (mid 2012) has the following specs:
2x Intel X5690
96GB
Sapphire RX580 Pulse 4GB
Aqua computer kryoM.2 PCIe 3.0 x4 adapter which holds the NVME drive and is installed in slot 1.

Can you please help ? Did I mis something ?

P.S: I still want to maintain the main drive with high sierra and OpenCore installed.

Don't use spoofing to install a supported macOS release.

Remove your OC drive and then boot a createinstallmedia USB key to install Mojave without OC. After Mojave is fully installed, you can install OC to the EFI partition or put back your OC drive.

Thanks for you reply. I was also searching this forum and stumbled across other post which suggested to turn off SMBIOS. I was in doubt so I started this thread. I will try your suggestion.

@tsialex Thanks! I have managed to successfully install Mojave on my NVMe drive. As you suggested I have removed all drives which have some kind boot partition. Then inserted the bootable installer USB and let it install. After succesfull Mojave install I put the other drives back. I had to rebless the SSD drive which holds OpenCore and HighSierra to get the bootpicker back. Now it's running beautifully both HS en Mojave.

But what if my OC and High Sierra are on the same drive in my case NVMe on PCIe slot 3.
