First of all, I am new to Mac and I have a few problems, questions... I have been looking through the Spotlight settings and have heard that if you disable it, it can drastically improve your battery life. After disabling it through System Prefs> Spotlight> Privacy and removed all... I have decided I want it back, but can't seem to get it working again, help? My other dilemma is that Apple is replacing my new UMBP due to a faulty keyboard... thing is I want to back-up the current state of my UMBP so I can load it during setup on my UMBP replacement and keep all my files. My current external 1TB was used for PC only with windows, does it need to be formatted? What is the best/quickest way to clone or back-up my current UMBP? How do I load it on my replacement UMBP right away? Thanks for your help!
