Hello everyone.. I have a question here. I have a a Macbook Pro 2011 that is running the latest Yosemite OS. I've never done a clean install on this system and I feel my system sluggish at times so this time around I will do a clean install of El Capitan. Thing is, after I do a clean install I plan on using Migration Assistant to restore my files, apps and settings to what they are right now. By doing that is it really worth doing a clean install or should I just install the new OS on top of the existing one?? Is there a better method to restore my files and apps?
