Had this computer 5 days maybe.Issue 1: with only one browser running and Roboform (password app) with 8 gig of Ram, I am out of memeory. I get pop-ups telling me to close seomething.What can I possibly close so I can still use my computer? Memory usage shows 7.8 gig. With what? Asked someone who is an expert on this and was told they can't find anything that eats RAM. Browser is using about .5gig of RAM, Roboform another .1gig. Who knows what the rest is used for. It doesn't show up in System Monitor.Tried all sorts of things, no dice.Now, a day later while I try to clean up the computer, the second (from the right) USB port quit working.Yes, I tested it out. It's dead.I only have the Mac for 5-6 days and it's supposedly in. ' excellent codition'. Really/II got my money back, so not complaining abou that, but for $460, I would expect it to be in better shape.This one is a dud.
