Any idea why a 2012 Mac Mini 2.3 Quad-Core with a 1TB Fusion drive would suddenly slow down loading webpages in Safari. One day everything was find and the next day it took several minutes just to load Macrumors.com. So far I have erased the cache, shut down and restarted the Mac Mini, even restored a Time Machine backup but the problem persists. Right now I'm in the middle of a complete wipe and fresh install. Any idea if it doesn't work after that?
