Hi! I have a 2011 27" iMac with a 3-year Applecare. I'm getting tired of juggling files between my external and internal drives, so I've been thinking about putting in a 3tb drive to replace my 1tb. I've looked up HDD replacement tutorials and it seems above me, I don't want to risk it and I know it'll void my Applecare. Is it possible to get this done through an authorised repairer/retailer without voiding Applecare? Can I throw money at Apple and have them put a bigger drive in?
