Hi guys, I am a PC technician by trade and finally decided to try out a Mac. So today I bought a Mac Mini. So far I am really liking it. This is the first Mac I have really used and am finding it pretty easy to catch on (not like Linux). Anyways, as a new user I have some really dumb questions: Do I need to worry about virus protection? Do I need to worry about spyware and adware? I am only running a few programs and the OS kinda feels like it is chunking up a bit (a term I use for when the OS is not as responsive) is 256MB enough RAM? Can I use my PC RAM to upgrade? Is there any built in utility that tells me what my memory usage is? Now this will sound dumb, but I had always assumed that Macs were just such a good computers (at least that is what all the Mac users have been telling me) that a crappy video card like what came with my Mini would still run some games (like Battlefield 1942). Is this true? Crud!! I had more questions but this all I can think of right now. I am sure I will have many more questions as time goes on, for now I am having a lot of fun exploring. Thanks for the help.
