I just purchased a 2015 refurbished MacBook pro from Apple along with apple care. Switched over from pc when I upgraded my Samsung NP900 laptop to windows 10, did not like it and during the rollback it deleted my Samsung drivers. I intend to have it reimaged and then sell it. Hate Microsoft. Anyway, is the apple like a pc where I will need to update the software once I get it? What do you recommend that I do initially? Thanks for any advice!
