hi all, My cousin has a macbook pro, and was wondering what free, reliable software there is out there for defragging on a mac? My cousin's macbook pro is a 15" from late 2011, with the 2.2 i7 and 4GB of memory, with the 5400rpm hard drive. Recently his macbook pro has been taking an age to load up, by like a minute to load. Is there any defragging software out there or anything that can increase the speed of my cousin's mac without having to spend money or very little money. all help is appreciated! -sam.
