My 2018 Mini has a display hardware problem. Vertical line down center of display. I tried the display on another Mac and no problem. I’ve reset the SMC and booted into Safe Mode and the 2018 still shows the problem. Ran Hardware Test that found no problem. Apple wants me to send it in under warranty however I did swap in a Crucial RAM upgrade back when I bought it last November. It has run great until now. Do I need to swap the original RAM back in before I send it in?
