Finally received my new i7-7700k CPU and now my rx580 is working. When I run RunMe I get into an ever ending loop - "IOREG dump failed. Retrying. Increased delay x2 for IOREG dump. This will take a while... (33 sec)".
I've added RunMe to Security & Privacy. I also copied IORegistryExplorer to Applications.
What else do I need to do?
Thanks!
