This started yesterday. I have a macbook pro that I purchased less than a year ago. Yesterday I was looking on the web and every time I clicked something else it wouldn't do anything. I would only have to click once on my mouse pad. Now I have to click multiple times. Sometimes I think it's back to normal cause it works with just one click, then I click another thing and I would have to click it like 10 times. What's wrong? I thought if I just restarted my computer it would be fine. I did that and it's still the same
