Hi all,
I've posted this here as well, since this issue is potentially hardware related.
I've been running into an issue attempting to install Mojave on a late 2013 iMac 27", currently running High Sierra 10.13.6, firmware v146.0.0.0.0, internal drive is a 2TB spinning HDD (and most of that disk space is not used, if anyone is wondering). IIRC, it has 16GB RAM.
The installer runs briefly and then returns the error saying it can't install the OS due to an error verifying the firmware. I tried several times, including once after resetting the NVRAM as one post suggested trying.
I've seen a few posts discussing this issue but none seem to be applicable to this situation except for this post, where repairing the firmware is discussed (see post #10):

The above thread is about a similar issue when trying to update to High Sierra, but could the same solution from post #10 apply here?
Or do you have any suggestions otherwise?
Any help is greatly appreciated. Thanks!
