Troubleshooting: Reporting Problems

Read this before opening an issue. Most problems have a known solution.


Before Reporting


What Is and Isn't Supported

Supported Not supported
Apple Silicon Macs (M1–M4) running macOS 11.0+ Intel Macs
macOS 11 (Big Sur) through macOS 26 (Tahoe) Hackintosh / patched macOS
Official releases from Releases Builds you compiled yourself (unless reporting a build issue with reproduction steps)

Common Issues with Known Solutions

Input / controller not working → See Troubleshooting: Input Problems — the most common cause is a missing Input Monitoring permission.

CD-based game won't import or launch → Follow the CD-Based Games guide exactly. No additional help beyond the guide will be offered for CUE/M3U problems.

System won't start — asks for BIOS → See BIOS Files — install the correct BIOS file by dragging it onto your library window.

Cover art not loading → Go to OpenEmu → Preferences → Cover Art and enter your ScreenScraper.eu credentials.

Core not appearing / system missing → Check OpenEmu → Preferences → Cores and install the missing core.

"Cores" aren't responding after a macOS update → You may need to re-sign your installed cores. Open Terminal and run:

codesign --force --sign - ~/Library/Application\ Support/OpenEmu/Cores/*.oecoreplugin

What to Include in a Bug Report

Use the Bug report template and include:

  • Mac model and chip (e.g. M2 MacBook Pro 14")
  • macOS version (e.g. macOS 15.3 Sequoia)
  • OpenEmu-Silicon version (from the title bar or About screen)
  • Which system and game — ROM filename if relevant
  • What happened vs. what you expected
  • Console and crash logs — see Troubleshooting: Console and Crash Reports
  • Steps to reproduce — exact sequence to trigger the problem

The more specific, the faster the fix. Vague reports ("it crashes sometimes") are very hard to act on.


What Not to Do

  • Do not post "+1", "me too", or "any update?" comments — these add noise without helping
  • Do not link to or name ROM download sites
  • Do not follow tutorials found on YouTube — they are often outdated or wrong
  • Do not open an issue without searching for duplicates first
