My new iMac has the flickering problem so I'm returning to get a new one. The problem is I've already gone and added all my files and applications to the faulty Mac and am not looking forward to doing it again. Is it possible to copy the entire drive (I have the single 2TB drive in the current machine) to the new one? I've been keeping Time Machine backups - would it be as simple as starting the new machine and plugging in my Time Machine external drive? Thanks in advance.
