More info:

Here are the specs. This error come after booting from usb with the ipxe.efi from clean fog install. snponly.efi doesn’t load either. The issue seems to be similar to some of the other unsolved topics but I haven’t seen any updates since November and am trying to see if any progress has been made or if there is anything that needs testing.

About Mac:

macOS High Sierra
Version 10.13.3
iMac (21.5-inch, Mid 2014)
Processor 1.4 GHz Intel Core i5
Memory 8GB 1600 MHz DDR3

Graphics Intel HD Graphics 5000 1536 MB

NIC: Broadcom 57766-A1

I have just deployed a new Fog server version 1.5.0-RC-13 and have been unsuccessful in getting an iMac to connect and image. I see there are some unsolved topics about this and was wondering if anyone had any updates on any of these topics.
