Nevermind, I actually figured out how to post in EAHQ
Go to Edit Town, do not save, just continue. Click on the house your sim lived in and you will find your sim in there. At the bottom of that box you will find "evict, merge, merge with, etc - click the Play this Household button. It will let you play your sim and they didn't loose any skills or money while in Uni. Everything in the house is still the way you left it. I played it a while and then saved and quit. Restarted computer and played again with no problem.

This is the post/thread I wanted it in: https://answers.ea.com/t5/Technical-Issues-Mac/Sim-is-missing-after-completing-university/m-p/9723737#M14164
I am still not good at this stuff, but this worked for me.
Thank you @puzzlezaddict appreciate all you do with helping everyone
