Hi, new to the forum and auto cad in general, I have been working my way through YouTube tutorials with some success. What I have found though is I don’t have the same options as is available in some of the videos, not sure if it’s because I am using Mac and the video user is Windows.

My issue is when I go to make a circle, the user in video has the option to go to command line and click on diameter, I don’t have the ability to do this, diameter is in the command line but when I pass over it I can’t select it. I also have this issue with other commands? 

Any help would be greatly appreciate, thanks!
