...now that i have an imac it cant even find the netwrk and let me get internet radio...The Touch gets it's IP address from your router, not the PC or iMac. The computer doesn't even have to be on for internet radio.
Are you saying the Touch doesn't see your wireless network?
Did you ever set up an account with mysqueezebox.com? You do need that for internet radio.
I've always found the users at forums.slimdevices.com very knowledgeable and helpful. It's not the official Squeezebox help site, but rather a users discussion group. You might wish to check them out.
