OS X went back to original files
I have two Apple iMacs with both 10.6.8 Snow Leopard.Since I'm planning a huge trip I don't have time to backup everything on DVDs and Blu Ray Discs. So I transferred everything from the old computer to the new one using a data cable. Except I probably shouldn't have transferred the System Libraries and User files because now all my dock programs are set to the old format and all the applications are asking me to re-input my serial numbers. The desktop picture also changed to the old one. I then burned just the System files to Blu Ray Discs and then deleted those but still everything is messed up. What happened with the new computer's preferences? Is there a way to get it back?
