Hey guys! I purchased my 27" iMac a few months ago, and I was very happy with it up until the release of the Battlefield 3 beta. I discovered that my iMac (as amazing and beefy as it is) is just not equipped to run this game the way I want it to, and I put it up on ksl and craigslist for sale. I will be building my own gaming PC rig with the money. (I still have my MacBook Pro, no worries, apple fanboys!) Two questions: 1- How can I erase the hard drive, and make sure that it is completely clean and ready for the next user? If I boot using OS X Lion's recovery partition, and use Disk Utitily to wipe the hard drive, will that do it? If so, will I need to even re-download OS X Lion? What do you recommend that I do? 2- I have a bunch of movies, tv shows and music (as well as documents) backed up on my Time Machine. Assuming files are compatible, can I plug in my external drive into my new Windows 7 PC, and access the files? Or do I need to convert it somehow? Thanks for any/all help!
