  try the netinst images instead and when you do the copy
make sure it is sync'd before removing USB device.  on my
system the cp returns very quickly but the sync may take
some time before everything is written to the USB stick.

While chasing down a completely different issue unrelated to this install, I learned that EFI boot drives need to have a GPT partition table. On a lark, I ran "gparted --list", and discovered that the flash drive had a "mac" partition table.

Wha-a-ah-h-h??

Okay. So I ran gparted, selected the drive, and created a new "GPT" partition table, then repeated all my former steps, and bang! Success! It's currently pulling down gobs of stuff (I elected to install Cinnamon and KDE and Gnome - always fun to overload a drive unnecessarily ;-) ).

Well, the trackpad still doesn't work in the installer, but I have half a suspicion that once the system boots, the trackpad will work. We'll see in a few.


Thanks for the responses, all!
