I'm going to be getting my first Mac in a week or so (yay!) and had a Comcast High-Speed Cable Modem question as it pertains to my new Mac Pro. I don't know why I hadn't thought about this until know but I just took for granted I wouldn't possibly encounter a possible problem in regards to switching from PC to Mac and Comcast. I tried getting info on the Comcast site, but no luck. So here's my question...Is there something different I need to do when I get my Mac Pro set-up with Comcast; or is it just a plug-and-play thing where I'll get connected with my Comcast Cable Modem when I plug it into the modem line? It's been so long since I had my PC installed that I don't know what extra I had to do to get my modem up and running in the first place with my PC. Thanks!
