For some reason, lately, I cant so much as download a file without my MBP sounding like a 737 during take off. Its also been beach balling A LOT lately, network connections are very slow (5Ghz N only) and frequently drop, and Ive had a lot of hard lockups that require a good 'ol hold the power button to make it restart. Im extremely frustrated & ready to throw my Mac out the window. What happened to OSX that made it like this? It used to run so smoothly, now it feels very slow & unstable. Whats wrong with it? Why is it doing this?
