First of all, I am not a "newbie" to Macs at all. I've been using Macs of various types for about 30 years, including making Hackintoshes. I am a newbie to recent Mac models, though. My main area of expertise by far is Linux, and I had never before used a Mac newer than a Core 2 Duo model. I recently purchased a Mac Mini Mid-2011 model used, so I could consolidate some of my mom's old writings. She recently passed away, and preferred to do her writings on Macs. She was using a Core 2 Duo Mac Mini, which stopped working. Is there any way to get this thing to use the HDMI port by default instead of the thunderbolt port? I had a multipurpose mini displayport adapter (which I've been using with a Surface Pro), but lost it in a recent move. I have tried various HDMI monitors and TV sets around the house, and when I connect the Mac Mini via HDMI, I just get a blank screen. I assume I am in a catch-22 here, that I need to hook it up to a monitor using the thuinderbolt/mini displayport connector and go into preferences to tell it to use the HDMI connector. But I can't do that because I have no adapter to use that port. I tried booting into safe mode, no go. Any help would be appreciated.
