what programs do I need to keep my mac running top-notch. Do I need some kind of spyware like avg free? or anti virus. I'm new to macs and I want to make sure I keep mine running good.
In fact, there isn't much you need to do to keep your Mac running smoothly. Your Mac would run automatically some maintenance processes while you don't use it.
yes i agree with roco, the only thing i have is diskwarrior. it basically defrags your computer. i only use that and disk utility (which comes with osx).
