I was trying to install Mojave on newly built pc, I am stuck at this apfs-module-start 1393 error right now. I tried downgrading the bios version of my motherboard. Tried different KEXTS, EFI folders but didn't work. I have installed windows 10 on it right now.

Can some one help me on this.

Having the same issue. I tried the "300 series RTC Bug Fix" and OS will not boot beyond "Start ReadKernelCache." When the bug fix is removed, I get hung up on "apfs 1393." Any further solutions for this bug? Thanks!
