hello everyone, i have a macbook that is about a year old. it has been consistently updated and i've never had a problem with it. However, just recently, any sort of online video i try to watch takes a very very long time to load. I haven't ever had this problem before. I am using the same wireless network from my home and the same type of high-speed internet. Everything else online loads just as fast as always, the videos just take extra long. Please help!
