Hey guys! So, tomorrow I will be selling my iMac. I have had an external HDD hooked up with Time Machine since the very day that I turned on the computer (maybe 3 months ago). Even though the iMac is going, I still have a MacBook Pro. I would like to keep my latest backup (basically a copy of exactly how my iMac is right now) so that I can access movies/music/photos from the HDD. I'm just wondering...to free up space on the HDD, can I delete every backup except for the most recent one? Or does the most recent backup only have the newest changes? Basically...what would you guys do? The best way to hang on to all of the files on the iMac, using the HDD that I've been using as a Time Machine backup this whole time? Thanks for any/all help!
