Alright, I've got a macbook I got about 10 months ago and for the past couple months it's been really lagging. Sometimes the spinning beachball will go for 3 or 4 minutes just trying to open a browser or the calendar. I've taken it to the Apple store a couple times and they've tried for font conflicts, start-up issues, and have only found a problem with the amount of fragmentation. The last time I was there they recommended getting a defrag program and running it to clean things up. However, I hear all about how macs don't need defragmenting. On the other hand, Apple sells a defragmenting program in its stores. Anyone have any other suggestions on what might be causing the lagging?
