⚠️ Security Risk: Olarilla images are closed-source, third-party modifications. No one outside the uploader knows exactly what has been added. There have been historical reports of modified system files that can bypass SIP (System Integrity Protection) without your knowledge.
⚠️ Legal Gray Area: macOS is proprietary software owned by Apple. Distributing pre-installed macOS images violates Apple’s EULA. Use these for educational or legacy hardware preservation only.
⚠️ Outdated Bootloaders: Many Olarila Catalina images ship with older versions of Clover. You will likely need to manually update the EFI folder after installation.
