Hi! Recently I noticed my Macbook Pro (I got it in 2011) slows down every time I download something from my browser. I tried using Safari to see if Chrome (my default browser) is causing the problem, but the same things happen regardless of what browser I use. Basically what happens is that whenever I download something, even if it's a super small file, everything becomes unresponsive and very slow and the cursor sometimes hangs too. The spinning beach ball also appears. After awhile things go back to normal, and I'm able to use my Mac properly again. Somebody please help! It's getting annoying Thanks!
