I use a $9.99 Targus mouse, it has r/l buttons, and a scroll wheel. I just plugged it in, and it worked, no messing with the prefs needed. All the buttons work, but I have found that the R button will download mp3’s, whereas the L button will play them.
that’s where you set the “primary” click - right or left.
The primary, usually the left, is your regular click operation, the other brings up context sensitive selections.
Thank you :) So, I can use my old mouse? What about my old keyboard? I think the mac ones are not very ergonomic. I have a Microsoft wireless mouse and keyboard that I’m so much more used to.
