Hello, I created the patched version and everything it's fine. I booted on a supported Mac and also installed HighSierra. I'm trying to do the same on an iMac7,1 but doesn't boot. I'm using a USB external disk and I tried with a USB drive 16GB. Both are recognised as a bootable volume at the start but when selected I just see the apple logo and nothing else, even the progress bar is not shown.
Any suggestion?
