Can’t generate OCLP High Sierra USB drive

[DominikHoffmann]

I am having a doozy of a time trying to make a USB drive with an OCLP-patched macOS High Sierra on it. I have tried different Macs and target media. I always get this:

For search engines: “Failed to create macOS installer”

OCLP (OpenCore Legacy Patcher) is at Version 1.5.0. Source OS macOS High Sierra 10.13.6 from /Applications/ . I haven’t tried having OCLP download its own copy of macOS for this or tried using an earlier version.

I did have success just now with making a OCLP Sonoma installation USB for a MacBook5,1. Could something be wrong with the copy of High Sierra I have?

Why are you trying so hard to make a patched installer, when High Sierra is not supported by OCLP in any way?
Better to use the patcher from dosdude1

You’ve made my day! I did not know that fact. Thanks very much for informing me! Doing a lot of barking up the wrong tree.

Yes - that's where I got a High Sierra installer from.
