So I'm brand new to Macs. I'm trying to relearn everything I know in Windows, and it's a bit overwhelming! Anyway I'm stumped by something that seems like it should be rather simple. I'm trying to listen to XM Radio Online. Safari tells me that the required plugin is not installed, but it doesn't give me any option to install it! So I installed Chrome thinking it would be smarter than Safari. Chrome shows me the little plugin icon, but it doesn't let me install the plugin either. How the heck am I supposed to install plugins in these browsers? I've been using PC's since the days of DOS. I've developed software, built web sites, built machines, created networks, etc. But now I feel like such a noob.
