This guide will will try to explain things as clearly as possible, but make some assumptions about your environment and your familiarity with the operating system. Most notably, that you are familiar with the basic operations of your PC (how to download files, how to extract them, etc.)
<aside> 🚨
WARNING: These guides assume that you already have the necessary files (firmware, keys, games, etc.) to run the emulator. Neither the Eden Team nor Their Discord will assist you in obtaining these files. Asking for these files on the Discord may result in a ban from the server without support or chance to appeal.
</aside>
Recent versions of MacOS (Catalina & newer) introduced the Gatekeeper security functionality, requiring software to be signed by Apple or a trusted (aka - paying) developer. If the signature isn’t on the list of trusted ones, it will stop the program from executing and display the message above.
See the Allowing Eden to Run on MacOS guide to get around this issue.
