I'm really thankful for this forum, especially this Mac Basics and Help section. I got my first Mac three months ago, and there are definitely challenges in learing how to use it. Sometimes I feel like I'm a computer newbie. There's something interesting going on with my trash contents. My habit in the past has always been to empty the trash as soon as I put something there. I'm not sure if that's the smartest thing to do, but I've always done it that ways. There's something unpleasant about an overflowing trash can... Anyway...sometimes when I empty the trash (usually without looking at the contents) it shows as many as 1800 items which need to be removed. Now I KNOW I haven't put that much in, so where does this stuff come from? I'm thinking maybe some kind of routine maintenance procedure that happens when my computer is sleeping. It takes a long time to delete and so far it's been the only time I've heard fan noise on my Macbook Pro. Any ideas?
