Looking for recommendations for service on a MacBook Pro (Mid-2012) in the Franklin County area. Out of the blue, the screen goes black and it is shutting down, and now I cannot get it to boot up. It will turn on and shut off within seconds and then it tries restarting over and over again and sometimes gives the prohibited symbol (circle with slash across it). It is acting almost as if it is overheating, but it doesn't seem to be. Fans working fine and not dusty inside. Swapped out stock HD a year or so ago with SSD and maxed out RAM. Has been running great since then until yesterday. Another note: When I upgraded to the SSD I had installed Big Sur on the machine as well (normally not supported on a MBP this old). I don't know if that could be part of the issue. Could this be a battery issue? Let me know of any recommendations where I could bring it for service in the area. I know of left-click in Amherst and Yes in Northampton, but wondering if there is anywhere else. Thanks for any ideas!
