    So, my setup is a Mac Mini model A1347 being used as a home theatre PC. it's a quad core with two hard drive setup. I only access it via Screens App, so I don't routinely keep HDMI attached to it.

    A few days ago I decided to upgrade it to High Sierra, not thinking to attach a monitor first to keep an eye on it. It was on for a few days, like it normally is, but upon trying to access it via screens I realized that I would likely need to initialize via HDMI. So I plugged in an HDMI cable and no signal was outputted. At this point I unplugged it so I could move it to an area where I could more easily work on it.

    Upon attempting to restart it, the Mini will only restart for about 30 seconds, and the only thing that happens is a spinning fan. I've tried outputting to HDMI as well as outputting via Mini DV to HDMI (I don't have a mini DV monitor).

    I don't have a wired keyboard for the Mac, so I can't try to reset NVRAM or do an SMC reset. Is there anything I can do short of buying a wired keyboard online to try this? And otherwise, my last recourse is taking it to the Genius Bar.

    Any help you the board might be able to offer would be greatly appreciated. I'd really like to find a way to not drive 45 minutes to the closest Apple store.

    Spend a little money for a cheap wired keyboard.
    Far better than anything wireless...

    I have a wired keyboard, but it’s windows layout. As I recall, I would need to enable it in the drivers of the OS before use?

    Just plug the keyboard in and try it.
    See what happens next.

    No drivers. Windows layout works just fine.

    ALT key is Option key
    Windows key is Command key
