Hello everyone, Our iMac is showing an error code "-501 0F." It seems to be running Mountain Lion. The issue appears during startup and displays the Apple welcome screen with this message. I suspect a system restore might be the best solution. No relevant results came up in my quick search, so I thought I’d ask for advice. Thanks for any assistance you can offer.
This message appears to be a warning or notification about an issue. Have you attempted starting in safe mode?
Many early issues stem from kernel crashes or hardware problems in OS X. They could use better guidance when reporting errors.
There wasn't any easy guide available. If they offer me a role, I'll just revert the system.
Restart the SMC and pram, then reinstall any swappable components.
Sounds like you're thinking positively—hope you give it a shot! Would rather keep it closed if possible, but I'm okay with that.
