Fixing External Display Issues on Mac Pro 6,1
The Mac Pro 6,1 (Trashcan) often experiences connection drops or black screens when using Thunderbolt 2 to HDMI/DisplayPort adapters under modern macOS.
Troubleshooting steps:
- Use Active Adapters: Ensure you are using an active Mini DisplayPort/Thunderbolt to HDMI adapter. Passive adapters often fail to negotiate resolutions correctly.
- Reset NVRAM: Reset the NVRAM (Option+Cmd+P+R at boot) to clear corrupt display geometry caches.
- Configure Refresh Rate: Go to System Settings → Displays and force the refresh rate to 60Hz or 30Hz instead of Variable.
