I have a late 2012 Mac Mini. I put in 2 new Crucial 8 gigabyte RAM sticks. Turned on computer and it recognized the new RAM. Once I put the cover on the Mac Mini, the RAM would not be recognized and the desktop screen would come on and off with every movement of Mac Mini. Tried the original RAM and that did not work either in both slots when it was working fine minutes before. I just have tried 20 different times with both RAM sticks, original.and new with the back cover off and the computer chimes and turns on, but does not advance because the RAM is not being recognized. I get a hero when the computer turns on when the RAM slots araree empty. What could be causing the issue and if I buy another Mac Mini, will I be able to transfer files from the old Mac Mini to the new Mac Mini if no RAM on the old Mac Mini works? --- Post Merged, Apr 21, 2019 --- Also, if I place the new or old RAM sticks into another Mac Mini, what are the chances of experiencing the same problem?
