Hey thanks for the replies in advance. I’ve been traveling back and forth for work so I haven’t had time to check this out. My macbook is a mid 2012 15 inch nonretina display. The 2.6 GHZ with 8 gb of Ram and the 750gb HD. Here is the info you requested.
Model Identifier:MacBookPro9,1
Hope it helps and can jog your memory so that I can finally resolve this issue.
