My new macbook pro 2010 has always taken a little longer than normal to respond to my commands, but nowadays it has become unbearable.. Whenever I try clicking on a link, scrolling a page, typing, or basically any command, that little rainbow wheel will show up and it will be stuck for about 20 seconds.. Anything I try to do on this computer now takes a very long time.. As I type this thread it has already stopped to "think" 4 times.. Does anyone have any idea of what could be wrong? Any steps I can take to try to fix it? Please help... My macbook is everything to me... lol Thanks!
