Really obscure process! I do thank you for trying to be helpful, but I can't figure it out yet. Stuck on STEP ONE. Read this entire thread...
Post 74, Sanchayan says, "If you follow the directions of the OP, open the macOS install Mojave/Sierra/high sierra.app package in Applications (do so by right click , show package contents)z you'll see in the contents and sharedsupport (inside contents folder), the files are copied from the macOS install data directory to SharedSupport, as the cpio command is supposed to."
Follow the instructions of OP how far? Could you tell us which post # you're referencing, and which line to stop at?
Then, when I tried to "see in the contents and sharedsupport" I didn't find any "sharedsupport."

Could somebody consolidate these instructions, and tell us what to do for High Sierra, and what to do for Mojave?
I'm using a Hackintosh (dual boot with Windows 10) with El Capitan built 2-1/2 yrs ago and not updated since, that I want to switch to Mojave. I'm hoping to save the old system, in case I have trouble with the new one, so I have a brand-new, unused SSD to install Mojave onto (planning to use a Time Machine backup to retrieve old settings and data).
Thought I might be able to do this myself, since I have no one nearby that knows Hackintoshes, but trying to pick one instruction from one post, and another from three pages later...meanwhile figure out which apply to me, and which don't...
