I know that this has been discussed somewhere before but could not find it, and I apologize for the location as well was not sure where to place this exactly to get the best answers. I am trying to do some online unix programing classes and a few others as well through the military and the website is not compatible with OS X. Does anyone know what causes this? Or if there are any ways that I can make it work? If anyone can help I would appreciate it. Thanks in advance. Also if the moderator would know where I could get better results for answers and move it thank you, and sorry again.
