Preferential Treament
Your Mac performs a few house- keeping routines early every morning around 2am which keeps the system running sweetly however if you close down your Mac everynight you might be heading for a few problems, there are a few applications that can perform the same routines as your Mac would normally do. Preferential Treatment can do all that the mac does with a few more bells and whistles as well, it also freeware. you can download it here, but you will need to install the bsd subsystem on your mac if you haven’t already (its on your original OSX install disks).
