I have a 2011 MacMini with 8 gigs of RAM, plenty of storage, and few extensions running, yet the Mac has slowed to a crawl. I get the spinning pinwheel of death constantly. Try to author an email, the processor is running. Try to launch an app, have lunch and come back after ten beers and it’s still loading (though you’re loaded faster than it). Apps like InDesign and font managers are unusable.
I’ve tried the usual: CleanMyMac2 and Onyx. I’ve reset the PRAM. I’ve tried creating another user and the same slowdown soon ensues. Right now I’m reinstalling the latest Mavericks release but I doubt that will help.
What to do?
