Enabling Adobe Flash Player in Safari is technically feasible on legacy macOS and Safari versions, and involves lowering plugin blocking, modifying hidden preferences, and accepting significant security risks. For any modern macOS (10.15+), the operating system prevents Flash execution entirely. Organizations requiring Flash content should migrate to emulation layers (Ruffle) or isolated virtual machines rather than attempting native plugin activation.

This is the most popular modern alternative. It is an open-source emulator that allows you to play Flash games and animations directly in your browser without needing the original Adobe plugin.
