Since I got my Macbook Pro back in June, boot times and loading times of apps seems to of gotten longer. I ran iDefrag to see what was going on and the most fragged file was lichking.MPQ which, as most of you may know, is the new World of Warcraft expansion. it is a large file (2.4gb). iDefrag reported my HDD being 28% fragmented. My question is, should or do I need to defrag? It has been asked a 1,000,000 times I know but I just can't seem to get a simple yes or no answer anywhere. Some people say yes, some say no and some say defragging my mac caused a hard drive failure etc.. What are your experiences and opinions? Thanks a lot!
