Hello Everyone, I'm in the process of installing a new hard drive on my wife's 2012 Macbook Pro (OS X 10.7 Lion). The device starts up, but we are experiencing the "spinning wheel of death" which I assume is from a dying HD. Swapping the drives is not an issue for me, but my questions revolve around reinstalling the OS & software/application recovery. Although she says that there are not any files, docs, etc worth keeping if lost in a fresh install, I would like to have the computer return to it's current state after I replace the hard drive, keeping the files, docs, & installed applications in order. So here are my questions: 1) She is not currently running Time Machine, & we do not have an external drive right now to backup everything. Is this necessary to proceed, based on what I am looking to do from the explanation above? 2) Could I bypass question 1 by Cloning the current drive, then re-installing once the new drive is configured? 3) Can I bypass questions 1 & 2 by launching the Disk Utility menu once the new drive is installed, repair/erase the new disc, then reinstall OS X (& would this return the computer to it's last configuration without doing 1 & 2)? This is fairly new to me, so I appreciate any insight & I thank you in advance!
