I have had my MBP for about a month now. Its my first laptop and my first Mac. I am really loving this thing, its a true powerhouse of a machine. Anyways, I am so used to running maintenace programs in windows to keep everything smooth. Virus scans, defragging, adaware, so on and so forth. I know that you dont have to defrag in OSX and macs do not get viruses for the most part. My question is are there any programs or utilities that I should be running to keep OSX runnning smoothly?
