Contrary to popular belief, Apple does not distribute macOS in standard ISO format, which is common for Windows or Linux. Instead, Apple uses a .app bundle downloaded through the Mac App Store. For El Capitan, Apple no longer lists it prominently, but the company maintains a support page where users can still download older installers. These are officially signed and verified, ensuring no malicious code has been injected. The legitimate method involves using a compatible Mac to download the "InstallMacOSXElCapitan.app" directly from Apple's servers. From there, users can create their own bootable USB drive or, with third-party tools, convert the .app into an ISO if needed for virtualization platforms like VMware or VirtualBox.
