So, my 2012 mac pro has a bad logic board and needs replacing. I am looking for help replacing it. Should I get a used 2010 mobo or should I be looking for a 2012 working pull. I can't get a new one cause that costs almost as much as a new computer so I am looking at used ones. So here are my questions. 1. Will a 2010 logic board work in my machine? 2. If I get a 2010 logic board, will my Mac pro be identified as a "Mid 2010". 3. Will the serial number also change? Thanks in advance guys.
