I did the following.

0) get 6GB file from Apple: "installer for Mojave" app -- left it in Applications
1) get some brand new Philips USB sticks 64GB.
1) oops, 64GB is too big. use Kingston 32GB USB stick
2) format stick per instructions as Extended Journaled, GUID. Name it MOJAVE.
3) run latest version of Unibeast
4) answer the questions: install Mojave, UEFI, put it on MOJAVE stick, no graphics card injects 'cos I'm going AMD this time
5) (long pause, animation)... error message

I read in another thread...


...that this error might be harmless. The USB stick looks like it got created OK (Install partition and EFI partition). So I'll give it a try when I get the new hackie powered up. Is there any way to tell just by looking?

First power-on test s/b tomorrow (anxious moment for a newbie builder like me, it's only my 2nd one).
