Mountain Lion isn't working very well on my iMac, so I've decided to do a clean reinstall of it. I've got some questions, though: 1. iLife - am I going to lose it? I don't have the App Store versions of iLife as my iMac is a 2010 model. What about iDVD and iWeb (do I need to get those off of my external hard drive after the install)? Can I use my Snow Leopard Applications Install DVD that came with the computer? 2. After the install, how can I get my old data off the external hard drive? You can't use Time Machine without reformatting the external drive, right? Can I just plug it in, go straight into Finder, and copy the files from Backups.backupdb?
