Hi everyone! I have a mid-2010 iMac and after 3 years, it's a total mess. Files & applications all over the place, desktop saturated, very slow speed, etc. It's time for a summer cleanup. What do you recommend doing at this point? Should I set the iMac back to factory settings and reinstall everything? This seems like a nightmare though. Or is their a way to get it fresh again by cleaning it up manually, going through all folders, etc?
