I recently installed several applications on my MBP and since then it has been taking much longer to load up, which I was thinking might mean it needs to run though its scheduled maintenance (defragging and the like). However, from what I understand OS X does this generally in the wee hours of the morning. I tend to put my MBP to sleep before I go to bed and generally don't wake it up until I get home from work the next day, so I was wondering if it has been able to do the maintenance or if it does it while it's asleep. Also, is there a program or way to check when the last time things were run that someone can recommend? Thanks for any help.
