Hello,
I am totally new to Linux, I can barely use Terminal/Console to enter commands, have no real clue what I'm doing. I am a Mac user who knows how to point and click, that's about all. I heard about EasyOS as a secure/private OS, and am very eager to use it.
I can boot EasyOS on my iMac from a USB Stick, but would like to try it on my WD Red 4TB External HDD (spinning platter *not SSD). I am using easy-3.4.7-amd64.img.gz
I have read Barry's instructions on "How to install EasyOS on your hard drive" -- April 24, 2022, and have very carefully duplicated his process for my iMac (twice) but when I "Alt" Boot, my external HDD with the EasyOS Boot partition and Working partition do not show as an option. I have used GParted to partition my external HDD, and made the changes to enable encryption, and changed the Initrd file per the 2022.04.24 notes by Barry. I cannot find a folder named EFI anywhere on my USB of easy-3.4.7 OS, otherwise I have exactly followed all instructions.
Any help with this will be greatly appreciated! Thanks in advance 
My equipment:
Mac OS 10.13.6 High Sierra (Due to older hardware, this is the newest version I can run)
