Distributing a pre-made macOS High Sierra 10.13.5.iso occupies a legal gray area. Apple’s EULA for macOS allows installation only on “Apple-branded computers.” While converting for personal use on a genuine Mac or a virtualized Mac host (on Apple hardware) is generally tolerated, distributing the ISO to third parties violates Apple’s copyright. Moreover, downloading random ISO files from torrent sites or file-sharing forums poses severe security risks: attackers can bundle malware, rootkits, or keyloggers into the modified system image.

The safest approach remains self-creation from a legitimate installer. For enterprises, using Apple’s own createinstallmedia or a macOS Server caching service is the only compliant method.

Apple’s EULA allows macOS to be installed only on genuine Apple hardware. Using an ISO to run macOS on a Hackintosh or a non-Apple VM technically violates these terms. However, downloading the installer for use on a real Mac is permitted.
