I am new to the iMAC OS X and am having some problems that I hope someone can help me with. I do home transcription and bought a foot pedal that is compatible with the MAC and the software I downloaded. However, I cannot get the foot pedal to connect to the software so that I can use it. When I go to system preferences, click on control everything is there for the foot pedal but it just doesn't work. How do I connect this to the software? I called the place where I purchased the foot pedal but they could not help me because they do not know the MAC. Anyone here can help me? Also, I tried to download a sound file - med80_1.rm.ram - but safari cannot open it without an application. How do I open sound files? I really need this as soon as possible so I won't lose out on several jobs. I bought he iMAC because I thought it would be a lot better than the PC I had, but seems I made a mistake.....I hope not.
