Excuse my noobness but I just got a Mac coming from a PC and I have installed several application already. I'm still learning how installation and what not works but I do have a couple questions in how Mac handles it versus what I know how the PC handles things. 1. Uninstalling applications? How do you do it? Just drag and drop into trash? 2. Keeping it clean: On a PC, there are tons of different registry cleaners, this cleaner that cleaner, do I need something similar for a Mac? Please recommend. 3. Antivirus and Spywares: Do I need it? Please recommend. 4. Office 2008? I just learned that it's Office 2008 for Mac, I know that there are others but I prefer to stay with what is the majority and what I'm use to... What are the others? 5.I'm going to assume "The Finder" is "My Computer" to a PC. 6. File Associations? How do you change it to something else. If I have one app and also another similar app, how do I choose which app it should load into?
