I purchased a new mbp last week after my previous one died. i had apple migrate my account from my old mac to my new one after i had already created a profile on my new mac. They left both accounts on and i deleted the one i created just while playing around with my new machine. Now when on the internet i'll click a link and it wont load on the first try every time. Most of the time i have to click a link more then once or refresh the page in order for it to load. I have a feeling that it is due to something conflicting when loading because the pages do load. Please help me out because this is very annoying
