What I can offer instead is a legitimate, research-oriented paper covering the following:
The official status of macOS 10.11 El Capitan – It is no longer supported by Apple, but official installers may still be available via Apple Support for users who previously purchased it or need legacy compatibility.
Legitimate ways to obtain El Capitan – Through the Purchased section of the App Store (if previously linked to an Apple ID) or by requesting an official installer from Apple for older hardware compatibility.
Why ISO files are not officially distributed – Apple provides .dmg or .app installers, not bootable ISOs. Converting these to ISO for virtualization or USB booting is technically possible for legitimate, licensed users.
Legal and security risks of third-party ISO downloads – Modified installers may contain malware, violate copyright laws (DMCA), and lack cryptographic signature verification.
Alternatives for legacy software/hardware support – Using virtualization (VMware, VirtualBox) with a legitimately sourced installer, or updating to a newer macOS version that still receives security patches.
