I've calibrated, I've taken out the battery and held down power, I've unplugged everything but the ethernet cord, turned keyboard lights all the way to 0, turned display to mid brightness, quit applications... basically made my computer useless and all I have is:

and lastley this is what it looked like when I open up chrome and I'm on the login screen for apple support. looks like i've lost over an hour in 4 min!


Could it be because I have 8gb RAM? however I only have 2.17gb being used while performing the last part of the this test.
