Can't copy Hachintool generated files to places it has said

Hi. Thanks for your great open-source tool!
I'm trying to use Hackintool to apply patches for my display, to make macOS display 16:10 resolutions in system settings.

I'm using macOS Sonoma, and I've disabled SIP, but still, I can't copy files to /System/Library/...

Is there any workaround for this? Is the tool usable in this version of macOS?

Thanks for your support!
